The Federal Bureau of Investigation (FBI) is the domestic intelligence and security service of the United States, and its principal federal law enforcement agency. Operating under the jurisdiction of the United States Department of Justice, the FBI is also a member of the U.S. Intelligence Community and reports to both the Attorney General and the Director of National Intelligence. A leading U.S. counter-terrorism, counterintelligence, and criminal investigative organization, the FBI has jurisdiction over violations of more than 200 categories of federal crimes.

Although many of the FBI's functions are unique, its activities in support of national security are comparable to those of the British MI5 and the Russian FSB. Unlike the Central Intelligence Agency (CIA), which has no law enforcement authority and is focused on intelligence collection abroad, the FBI is primarily a domestic agency, maintaining 56 field offices in major cities throughout the United States, and more than 400 resident agencies in smaller cities and areas across the nation. At an FBI field office, a senior-level FBI officer concurrently serves as the representative of the Director of National Intelligence.

Despite its domestic focus, the FBI also maintains a significant international footprint, operating 60 Legal Attache (LEGAT) offices and 15 sub-offices in U.S. embassies and consulates across the globe. These foreign offices exist primarily for the purpose of coordination with foreign security services and do not usually conduct unilateral operations in the host countries. The FBI can and does at times carry out secret activities overseas, just as the CIA has a limited domestic function; these activities generally require coordination across government agencies.

The FBI was established in 1908 as the Bureau of Investigation, the BOI or BI for short. Its name was changed to the Federal Bureau of Investigation (FBI) in 1935. The FBI headquarters is the J. Edgar Hoover Building, located in Washington, D.C.

Budget, mission, and priorities

FBI Domestic Investigations and Operations Guide
 
In the fiscal year 2016, the Bureau's total budget was approximately $8.7 billion.

The FBI's main goal is to protect and defend the United States, to uphold and enforce the criminal laws of the United States, and to provide leadership and criminal justice services to federal, state, municipal, and international agencies and partners.

Currently, the FBI's top priorities are:
  • Protect the United States from terrorist attacks,
  • Protect the United States against foreign intelligence operations and espionage,
  • Protect the United States against cyber-based attacks and high-technology crimes,
  • Combat public corruption at all levels,
  • Protect civil rights,
  • Combat transnational/national criminal organizations and enterprises,
  • Combat major white-collar crime,
  • Combat significant violent crime,
  • Support federal, state, local and international partners, and
  • Upgrade technology to enable, and further, the successful performances of its missions as stated above.

History

Background

In 1896, the National Bureau of Criminal Identification was founded, which provided agencies across the country with information to identify known criminals. The 1901 assassination of President William McKinley created a perception that America was under threat from anarchists. The Departments of Justice and Labor had been keeping records on anarchists for years, but President Theodore Roosevelt wanted more power to monitor them.

The Justice Department had been tasked with the regulation of interstate commerce since 1887, though it lacked the staff to do so. It had made little effort to relieve its staff shortage until the Oregon land fraud scandal at the turn of the 20th Century. President Roosevelt instructed Attorney General Charles Bonaparte to organize an autonomous investigative service that would report only to the Attorney General.

Bonaparte reached out to other agencies, including the U.S. Secret Service, for personnel, investigators in particular. On May 27, 1908, the Congress forbade this use of Treasury employees by the Justice Department, citing fears that the new agency would serve as a secret police department. Again at Roosevelt's urging, Bonaparte moved to organize a formal Bureau of Investigation, which would then have its own staff of special agents.

Creation

The Bureau of Investigation (BOI) was created on July 26, 1908, after the Congress had adjourned for the summer. Attorney General Bonaparte, using Department of Justice expense funds, hired thirty-four people, including some veterans of the Secret Service, to work for a new investigative agency. Its first "Chief" (the title is now known as "Director") was Stanley Finch. Bonaparte notified the Congress of these actions in December 1908.

The bureau's first official task was visiting and making surveys of the houses of prostitution in preparation for enforcing the "White Slave Traffic Act," or Mann Act, passed on June 25, 1910. In 1932, the bureau was renamed the United States Bureau of Investigation. The following year it was linked to the Bureau of Prohibition and rechristened the Division of Investigation (DOI) before finally becoming an independent service within the Department of Justice in 1935. In the same year, its name was officially changed from the Division of Investigation to the present-day Federal Bureau of Investigation, or FBI.

J. Edgar Hoover as FBI Director

J. Edgar Hoover, FBI Director from 1924 to 1972
 
J. Edgar Hoover served as FBI Director from 1924 to 1972, a combined 48 years with the BOI, DOI, and FBI. He was chiefly responsible for creating the Scientific Crime Detection Laboratory, or the FBI Laboratory, which officially opened in 1932, as part of his work to professionalize investigations by the government. Hoover was substantially involved in most major cases and projects that the FBI handled during his tenure. But as detailed below, his proved to be a highly controversial tenure as Bureau Director, especially in its later years. After Hoover's death, the Congress passed legislation that limited the tenure of future FBI Directors to ten years.

Early homicide investigations of the new agency included the Osage Indian murders. During the "War on Crime" of the 1930s, FBI agents apprehended or killed a number of notorious criminals who carried out kidnappings, robberies, and murders throughout the nation, including John Dillinger, "Baby Face" Nelson, Kate "Ma" Barker, Alvin "Creepy" Karpis, and George "Machine Gun" Kelly.

Other activities of its early decades included a decisive role in reducing the scope and influence of the white supremacist group Ku Klux Klan. Additionally, through the work of Edwin Atherton, the BOI claimed to have successfully apprehended an entire army of Mexican neo-revolutionaries under the leadership of General Enrique Estrada in the mid-1920s, east of San Diego, California.

Hoover began using wiretapping in the 1920s during Prohibition to arrest bootleggers. In the 1927 case Olmstead v. United States, in which a bootlegger was caught through telephone tapping, the United States Supreme Court ruled that FBI wiretaps did not violate the Fourth Amendment as unlawful search and seizure, as long as the FBI did not break into a person's home to complete the tapping. After Prohibition's repeal, Congress passed the Communications Act of 1934, which outlawed non-consensual phone tapping, but did allow bugging. In the 1939 case Nardone v. United States, the court ruled that due to the 1934 law, evidence the FBI obtained by phone tapping was inadmissible in court. After the 1967 case Katz v. United States overturned the 1927 case that had allowed bugging, Congress passed the Omnibus Crime Control Act, allowing public authorities to tap telephones during investigations, as long as they obtained warrants beforehand.

National security

Beginning in the 1940s and continuing into the 1970s, the bureau investigated cases of espionage against the United States and its allies. Eight Nazi agents who had planned sabotage operations against American targets were arrested, and six were executed (Ex parte Quirin) under their sentences. Also during this time, a joint US/UK code-breaking effort called "The Venona Project"—with which the FBI was heavily involved—broke Soviet diplomatic and intelligence communications codes, allowing the US and British governments to read Soviet communications. This effort confirmed the existence of Americans working in the United States for Soviet intelligence. Hoover was administering this project, but he failed to notify the Central Intelligence Agency (CIA) of it until 1952. Another notable case was the arrest of Soviet spy Rudolf Abel in 1957. The discovery of Soviet spies operating in the US allowed Hoover to pursue his longstanding obsession with the threat he perceived from the American Left, ranging from Communist Party of the United States of America (CPUSA) union organizers to American liberals.

Japanese American internment

In 1939, the Bureau began compiling a custodial detention list with the names of those who would be taken into custody in the event of war with Axis nations. The majority of the names on the list belonged to Issei community leaders, as the FBI investigation built on an existing Naval Intelligence index that had focused on Japanese Americans in Hawaii and the West Coast, but many German and Italian nationals also found their way onto the secret list. Robert Shivers, head of the Honolulu office, obtained permission from Hoover to start detaining those on the list on December 7, 1941, while bombs were still falling over Pearl Harbor. Mass arrests and searches of homes (in most cases conducted without warrants) began a few hours after the attack, and over the next several weeks more than 5,500 Issei men were taken into FBI custody. On February 19, 1942, President Franklin Roosevelt issued Executive Order 9066, authorizing the removal of Japanese Americans from the West Coast. FBI Director Hoover opposed the subsequent mass removal and confinement of Japanese Americans authorized under Executive Order 9066, but Roosevelt prevailed. The vast majority went along with the subsequent exclusion orders, but in a handful of cases where Japanese Americans refused to obey the new military regulations, FBI agents handled their arrests. The Bureau continued surveillance on Japanese Americans throughout the war, conducting background checks on applicants for resettlement outside camp, and entering the camps (usually without the permission of War Relocation Authority officials) and grooming informants to monitor dissidents and "troublemakers." After the war, the FBI was assigned to protect returning Japanese Americans from attacks by hostile white communities.

Sex deviates program

According to Douglas M. Charles, the FBI's "sex deviates" program began on April 10, 1950, when J. Edgar Hoover forwarded the White House, U.S. Civil Service Commission, and branches of the armed services a list of 393 alleged federal employees who were allegedly arrested in Washington, D.C., since 1947, on charges of "sexual irregularities". On June 20, 1951, Hoover expanded the program by issuing a memo establishing a "uniform policy for the handling of the increasing number of reports and allegations concerning present and past employees of the United State Government who assertedly [sic] are sex deviates." The program was expanded to include non-government jobs. According to Athan Theoharis, "In 1951 he [Hoover] had unilaterally instituted a Sex Deviates program to purge alleged homosexuals from any position in the federal government, from the lowliest clerk to the more powerful position of White house aide." On May 27, 1953, Executive Order 10450 went into effect. The program was expanded further by this executive order by making all federal employment of homosexuals illegal. On July 8, 1953, the FBI forwarded to the U.S. Civil Service Commission information from the sex deviates program. In 1977–1978, 300,000 pages, collected between 1930 to the mid-1970s, in the sex deviates program were destroyed by FBI officials.

Civil rights movement

During the 1950s and 1960s, FBI officials became increasingly concerned about the influence of civil rights leaders, whom they believed either had communist ties or were unduly influenced by communists or "fellow travelers." In 1956, for example, Hoover sent an open letter denouncing Dr. T. R. M. Howard, a civil rights leader, surgeon, and wealthy entrepreneur in Mississippi who had criticized FBI inaction in solving recent murders of George W. Lee, Emmett Till, and other blacks in the South. The FBI carried out controversial domestic surveillance in an operation it called the COINTELPRO, from "COunter-INTELligence PROgram." It was to investigate and disrupt the activities of dissident political organizations within the United States, including both militant and non-violent organizations. Among its targets was the Southern Christian Leadership Conference, a leading civil rights organization whose clergy leadership included the Rev. Dr. Martin Luther King, Jr., who is addressed in more detail below.

The "suicide letter", mailed anonymously to King by the FBI
 
The FBI frequently investigated Martin Luther King, Jr. In the mid-1960s, King began publicly criticizing the Bureau for giving insufficient attention to the use of terrorism by white supremacists. Hoover responded by publicly calling King the most "notorious liar" in the United States. In his 1991 memoir, Washington Post journalist Carl Rowan asserted that the FBI had sent at least one anonymous letter to King encouraging him to commit suicide. Historian Taylor Branch documents an anonymous November 1964 "suicide package" sent by the Bureau that combined a letter to the civil rights leader telling him "You are done. There is only one way out for you..." with audio recordings of King's sexual indiscretions.

In March 1971, the residential office of an FBI agent in Media, Pennsylvania was burgled by a group calling itself the Citizens' Commission to Investigate the FBI. Numerous files were taken and distributed to a range of newspapers, including The Harvard Crimson. The files detailed the FBI's extensive COINTELPRO program, which included investigations into lives of ordinary citizens—including a black student group at a Pennsylvania military college and the daughter of Congressman Henry Reuss of Wisconsin. The country was "jolted" by the revelations, which included assassinations of political activists, and the actions were denounced by members of the Congress, including House Majority Leader Hale Boggs. The phones of some members of the Congress, including Boggs, had allegedly been tapped.

Kennedy's assassination

When President John F. Kennedy was shot and killed, the jurisdiction fell to the local police departments until President Lyndon B. Johnson directed the FBI to take over the investigation. To ensure clarity about the responsibility for investigation of homicides of federal officials, the Congress passed a law that included investigations of such deaths of federal officials, especially by homicide, within FBI jurisdiction. This new law was passed in 1965.

Organized crime

In response to organized crime, on August 25, 1953, the FBI created the Top Hoodlum Program. The national office directed field offices to gather information on mobsters in their territories and to report it regularly to Washington for a centralized collection of intelligence on racketeers. After the Racketeer Influenced and Corrupt Organizations Act, or RICO Act, took effect, the FBI began investigating the former Prohibition-organized groups, which had become fronts for crime in major cities and small towns. All of the FBI work was done undercover and from within these organizations, using the provisions provided in the RICO Act. Gradually the agency dismantled many of the groups. Although Hoover initially denied the existence of a National Crime Syndicate in the United States, the Bureau later conducted operations against known organized crime syndicates and families, including those headed by Sam Giancana and John Gotti. The RICO Act is still used today for all organized crime and any individuals who may fall under the Act's provisions.

In 2003, a congressional committee called the FBI's organized crime informant program "one of the greatest failures in the history of federal law enforcement." The FBI allowed four innocent men to be convicted of the March 1965 gangland murder of Edward "Teddy" Deegan in order to protect Vincent Flemmi, an FBI informant. Three of the men were sentenced to death (which was later reduced to life in prison), and the fourth defendant was sentenced to life in prison. Two of the four men died in prison after serving almost 30 years, and two others were released after serving 32 and 36 years. In July 2007, U.S. District Judge Nancy Gertner in Boston found that the Bureau had helped convict the four men using false witness accounts given by mobster Joseph Barboza. The U.S. Government was ordered to pay $100 million in damages to the four defendants.

Special FBI teams

In 1982, the FBI formed an elite unit to help with problems that might arise at the 1984 Summer Olympics to be held in Los Angeles, particularly terrorism and major-crime. This was a result of the 1972 Summer Olympics in Munich, Germany, when terrorists murdered the Israeli athletes. Named the Hostage Rescue Team, or HRT, it acts as the FBI lead for a national SWAT team in related procedures and all counter-terrorism cases. Also formed in 1984 was the Computer Analysis and Response Team, or CART.

From the end of the 1980s to the early 1990s, the FBI reassigned more than 300 agents from foreign counter-intelligence duties to violent crime, and made violent crime the sixth national priority. With reduced cuts to other well-established departments, and because terrorism was no longer considered a threat after the end of the Cold War, the FBI assisted local and state police forces in tracking fugitives who had crossed state lines, which is a federal offense. The FBI Laboratory helped develop DNA testing, continuing its pioneering role in identification that began with its fingerprinting system in 1924.

Notable efforts in the 1990s

Between 1993 and 1996, the FBI increased its counter-terrorism role in the wake of the first 1993 World Trade Center bombing in New York City, New York; the 1995 Oklahoma City bombing in Oklahoma City, Oklahoma; and the arrest of the Unabomber in 1996. Technological innovation and the skills of FBI Laboratory analysts helped ensure that the three cases were successfully prosecuted. But Justice Department investigations into the FBI's roles in the Ruby Ridge and Waco incidents were found to have been obstructed by agents within the Bureau. During the 1996 Summer Olympics in Atlanta, Georgia, the FBI was criticized for its investigation of the Centennial Olympic Park bombing. It has settled a dispute with Richard Jewell, who was a private security guard at the venue, along with some media organizations, in regard to the leaking of his name during the investigation; this had briefly led to his being wrongly suspected of the bombing. 

After Congress passed the Communications Assistance for Law Enforcement Act (CALEA, 1994), the Health Insurance Portability and Accountability Act (HIPAA, 1996), and the Economic Espionage Act (EEA, 1996), the FBI followed suit and underwent a technological upgrade in 1998, just as it did with its CART team in 1991. Computer Investigations and Infrastructure Threat Assessment Center (CITAC) and the National Infrastructure Protection Center (NIPC) were created to deal with the increase in Internet-related problems, such as computer viruses, worms, and other malicious programs that threatened US operations. With these developments, the FBI increased its electronic surveillance in public safety and national security investigations, adapting to the telecommunications advancements that changed the nature of such problems.

September 11 attacks

September 11 attacks at the Pentagon
 
During the September 11, 2001, attacks on the World Trade Center, FBI agent Leonard W. Hatton Jr. was killed during the rescue effort while helping the rescue personnel evacuate the occupants of the South Tower, and he stayed when it collapsed. Within months after the attacks, FBI Director Robert Mueller, who had been sworn in a week before the attacks, called for a re-engineering of FBI structure and operations. He made countering every federal crime a top priority, including the prevention of terrorism, countering foreign intelligence operations, addressing cyber security threats, other high-tech crimes, protecting civil rights, combating public corruption, organized crime, white-collar crime, and major acts of violent crime.

In February 2001, Robert Hanssen was caught selling information to the Russian government. It was later learned that Hanssen, who had reached a high position within the FBI, had been selling intelligence since as early as 1979. He pleaded guilty to espionage and received a life sentence in 2002, but the incident led many to question the security practices employed by the FBI. There was also a claim that Hanssen might have contributed information that led to the September 11, 2001 attacks.

The 9/11 Commission's final report on July 22, 2004, stated that the FBI and Central Intelligence Agency (CIA) were both partially to blame for not pursuing intelligence reports that could have prevented the September 11 attacks. In its most damning assessment, the report concluded that the country had "not been well served" by either agency and listed numerous recommendations for changes within the FBI. While the FBI did accede to most of the recommendations, including oversight by the new Director of National Intelligence, some former members of the 9/11 Commission publicly criticized the FBI in October 2005, claiming it was resisting any meaningful changes.

On July 8, 2007, The Washington Post published excerpts from UCLA Professor Amy Zegart's book Spying Blind: The CIA, the FBI, and the Origins of 9/11. The Post reported, from Zegart's book, that government documents showed that both the CIA and the FBI had missed 23 potential chances to disrupt the terrorist attacks of September 11, 2001. The primary reasons for the failures included: agency cultures resistant to change and new ideas; inappropriate incentives for promotion; and a lack of cooperation between the FBI, CIA and the rest of the United States Intelligence Community. The book blamed the FBI's decentralized structure, which prevented effective communication and cooperation among different FBI offices. The book suggested that the FBI had not evolved into an effective counter-terrorism or counter-intelligence agency, due in large part to deeply ingrained agency cultural resistance to change. For example, FBI personnel practices continued to treat all staff other than special agents as support staff, classifying intelligence analysts alongside the FBI's auto mechanics and janitors.

Faulty bullet analysis

For over 40 years, the FBI crime lab in Quantico had believed that lead alloys used in bullets had unique chemical signatures. It was analyzing the bullets with the goal of matching them chemically, not only to a single batch of ammunition coming out of a factory, but also to a single box of bullets. The National Academy of Sciences conducted an 18-month independent review of comparative bullet-lead analysis. In 2003, its National Research Council published a report whose conclusions called into question 30 years of FBI testimony. It found the analytic model used by the FBI for interpreting results was deeply flawed, and the conclusion, that bullet fragments could be matched to a box of ammunition, was so overstated that it was misleading under the rules of evidence. One year later, the FBI decided to stop conducting bullet lead analyses.

After a 60 Minutes/Washington Post investigation in November 2007, two years later, the Bureau agreed to identify, review, and release all pertinent cases, and notify prosecutors about cases in which faulty testimony was given.

Organization

The FBI is organized into functional branches and the Office of the Director, which contains most administrative offices. An executive assistant director manages each branch. Each branch is then divided into offices and divisions, each headed by an assistant director. The various divisions are further divided into sub-branches, led by deputy assistant directors. Within these sub-branches there are various sections headed by section chiefs. Section chiefs are ranked analogous to special agents in charge. 

Four of the branches report to the deputy director while two report to the associate director. The functional branches of the FBI are:
The Office of the Director serves as the central administrative organ of the FBI. The office provides staff support functions (such as finance and facilities management) to the five function branches and the various field divisions. The office is managed by the FBI associate director, who also oversees the operations of both the Information and Technology and Human Resources Branches.

Legal authority

The FBI's mandate is established in Title 28 of the United States Code (U.S. Code), Section 533, which authorizes the Attorney General to "appoint officials to detect and prosecute crimes against the United States." Other federal statutes give the FBI the authority and responsibility to investigate specific crimes. 

The FBI's chief tool against organized crime is the Racketeer Influenced and Corrupt Organizations (RICO) Act. The FBI is also charged with the responsibility of enforcing compliance of the United States Civil Rights Act of 1964 and investigating violations of the act in addition to prosecuting such violations with the United States Department of Justice (DOJ). The FBI also shares concurrent jurisdiction with the Drug Enforcement Administration (DEA) in the enforcement of the Controlled Substances Act of 1970. 

The USA PATRIOT Act increased the powers allotted to the FBI, especially in wiretapping and monitoring of Internet activity. One of the most controversial provisions of the act is the so-called sneak and peek provision, granting the FBI powers to search a house while the residents are away, and not requiring them to notify the residents for several weeks afterwards. Under the PATRIOT Act's provisions, the FBI also resumed inquiring into the library records of those who are suspected of terrorism (something it had supposedly not done since the 1970s). 

In the early 1980s, Senate hearings were held to examine FBI undercover operations in the wake of the Abscam controversy, which had allegations of entrapment of elected officials. As a result, in following years a number of guidelines were issued to constrain FBI activities. 

A March 2007 report by the inspector general of the Justice Department described the FBI's "widespread and serious misuse" of national security letters, a form of administrative subpoena used to demand records and data pertaining to individuals. The report said that between 2003 and 2005, the FBI had issued more than 140,000 national security letters, many involving people with no obvious connections to terrorism.

Information obtained through an FBI investigation is presented to the appropriate U.S. Attorney or Department of Justice official, who decides if prosecution or other action is warranted.

The FBI often works in conjunction with other federal agencies, including the U.S. Coast Guard (USCG) and U.S. Customs and Border Protection (CBP) in seaport and airport security, and the National Transportation Safety Board in investigating airplane crashes and other critical incidents. Immigration and Customs Enforcement Homeland Security Investigations (ICE-HSI) has nearly the same amount of investigative manpower as the FBI, and investigates the largest range of crimes. In the wake of the September 11 attacks, then–Attorney General Ashcroft assigned the FBI as the designated lead organization in terrorism investigations after the creation of the U.S. Department of Homeland Security. ICE-HSI and the FBI are both integral members of the Joint Terrorism Task Force.

Indian reservations

 
The federal government has the primary responsibility for investigating and prosecuting serious crime on Indian reservations.
There are 565 federally recognized American Indian Tribes in the United States, and the FBI has federal law enforcement responsibility on nearly 200 Indian reservations. This federal jurisdiction is shared concurrently with the Bureau of Indian Affairs, Office of Justice Services (BIA-OJS).
Located within the FBI's Criminal Investigative Division, the Indian Country Crimes Unit (ICCU) is responsible for developing and implementing strategies, programs, and policies to address identified crime problems in Indian Country (IC) for which the FBI has responsibility.

— Overview, Indian Country Crime
The FBI does not specifically list crimes in Native American land as one of its priorities. Often serious crimes have been either poorly investigated or prosecution has been declined. Tribal courts can impose sentences of up to three years, under certain restrictions.

Infrastructure

The J. Edgar Hoover Building, FBI Headquarters

The FBI is headquartered at the J. Edgar Hoover Building in Washington, D.C., with 56 field offices in major cities across the United States. The FBI also maintains over 400 resident agencies across the United States, as well as over 50 legal attachés at United States embassies and consulates. Many specialized FBI functions are located at facilities in Quantico, Virginia, as well as a "data campus" in Clarksburg, West Virginia, where 96 million sets of fingerprints "from across the United States are stored, along with others collected by American authorities from prisoners in Saudi Arabia and Yemen, Iraq and Afghanistan." The FBI is in process of moving its Records Management Division, which processes Freedom of Information Act (FOIA) requests, to Winchester, Virginia.

According to The Washington Post, the FBI "is building a vast repository controlled by people who work in a top-secret vault on the fourth floor of the J. Edgar Hoover Building in Washington. This one stores the profiles of tens of thousands of Americans and legal residents who are not accused of any crime. What they have done is appear to be acting suspiciously to a town sheriff, a traffic cop or even a neighbor."

The FBI Laboratory, established with the formation of the BOI, did not appear in the J. Edgar Hoover Building until its completion in 1974. The lab serves as the primary lab for most DNA, biological, and physical work. Public tours of FBI headquarters ran through the FBI laboratory workspace before the move to the J. Edgar Hoover Building. The services the lab conducts include Chemistry, Combined DNA Index System (CODIS), Computer Analysis and Response, DNA Analysis, Evidence Response, Explosives, Firearms and Tool marks, Forensic Audio, Forensic Video, Image Analysis, Forensic Science Research, Forensic Science Training, Hazardous Materials Response, Investigative and Prospective Graphics, Latent Prints, Materials Analysis, Questioned Documents, Racketeering Records, Special Photographic Analysis, Structural Design, and Trace Evidence. The services of the FBI Laboratory are used by many state, local, and international agencies free of charge. The lab also maintains a second lab at the FBI Academy.

The FBI Academy, located in Quantico, Virginia, is home to the communications and computer laboratory the FBI utilizes. It is also where new agents are sent for training to become FBI Special Agents. Going through the 21-week course is required for every Special Agent. First opened for use in 1972, the facility located on 385 acres (1.6 km2) of woodland. The Academy trains state and local law enforcement agencies, which are invited to the law enforcement training center. The FBI units that reside at Quantico are the Field and Police Training Unit, Firearms Training Unit, Forensic Science Research and Training Center, Technology Services Unit (TSU), Investigative Training Unit, Law Enforcement Communication Unit, Leadership and Management Science Units (LSMU), Physical Training Unit, New Agents' Training Unit (NATU), Practical Applications Unit (PAU), the Investigative Computer Training Unit and the "College of Analytical Studies."

 
In 2000, the FBI began the Trilogy project to upgrade its outdated information technology (IT) infrastructure. This project, originally scheduled to take three years and cost around $380 million, ended up over budget and behind schedule. Efforts to deploy modern computers and networking equipment were generally successful, but attempts to develop new investigation software, outsourced to Science Applications International Corporation (SAIC), were not. Virtual Case File, or VCF, as the software was known, was plagued by poorly defined goals, and repeated changes in management. In January 2005, more than two years after the software was originally planned for completion, the FBI officially abandoned the project. At least $100 million (and much more by some estimates) was spent on the project, which never became operational. The FBI has been forced to continue using its decade-old Automated Case Support system, which IT experts consider woefully inadequate. In March 2005, the FBI announced it was beginning a new, more ambitious software project, code-named Sentinel, which they expected to complete by 2009.

Carnivore was an electronic eavesdropping software system implemented by the FBI during the Clinton administration; it was designed to monitor email and electronic communications. After prolonged negative coverage in the press, the FBI changed the name of its system from "Carnivore" to "DCS1000." DCS is reported to stand for "Digital Collection System"; the system has the same functions as before. The Associated Press reported in mid-January 2005 that the FBI essentially abandoned the use of Carnivore in 2001, in favor of commercially available software, such as NarusInsight. 

The Criminal Justice Information Services (CJIS) Division is located in Clarksburg, West Virginia. Organized beginning in 1991, the office opened in 1995 as the youngest agency division. The complex is the length of three football fields. It provides a main repository for information in various data systems. Under the roof of the CJIS are the programs for the National Crime Information Center (NCIC), Uniform Crime Reporting (UCR), Fingerprint Identification, Integrated Automated Fingerprint Identification System (IAFIS), NCIC 2000, and the National Incident-Based Reporting System (NIBRS). Many state and local agencies use these data systems as a source for their own investigations and contribute to the database using secure communications. FBI provides these tools of sophisticated identification and information services to local, state, federal, and international law enforcement agencies.

FBI is in charge of National Virtual Translation Center, which provides "timely and accurate translations of foreign intelligence for all elements of the Intelligence Community."

As of 31 December 2009, the FBI had a total of 33,852 employees. That includes 13,412 special agents and 20,420 support professionals, such as intelligence analysts, language specialists, scientists, information technology specialists, and other professionals.

The Officer Down Memorial Page provides the biographies of 69 FBI agents who have died in the line of duty from 1925 to July 2017.

Hiring process

To apply to become an FBI agent, one must be between the ages of 23 and 37. Due to the decision in Robert P. Isabella v. Department of State and Office of Personnel Management, 2008 M.S.P.B. 146, preference-eligible veterans may apply after age 37. In 2009, the Office of Personnel Management issued implementation guidance on the Isabella decision. The applicant must also hold U.S. citizenship, be of high moral character, have a clean record, and hold at least a four-year bachelor's degree. At least three years of professional work experience prior to application is also required. All FBI employees require a Top Secret (TS) security clearance, and in many instances, employees need a TS/SCI (Top Secret/Sensitive Compartmented Information) clearance. To obtain a security clearance, all potential FBI personnel must pass a series of Single Scope Background Investigations (SSBI), which are conducted by the Office of Personnel Management. Special agent candidates also have to pass a Physical Fitness Test (PFT), which includes a 300-meter run, one-minute sit-ups, maximum push-ups, and a 1.5-mile (2.4 km) run. Personnel must pass a polygraph test with questions including possible drug use. Applicants who fail polygraphs may not gain employment with the FBI. Up until 1975, the FBI had a minimum height requirement of 5 feet 7 inches (170 cm).

BOI and FBI directors

FBI Directors are appointed (nominated) by the President of the United States and must be confirmed by the United States Senate to serve a term of office of ten years, subject to resignation or removal by the President at his/her discretion before their term ends. Additional terms are allowed following the same procedure.

J. Edgar Hoover, appointed by President Calvin Coolidge in 1924, was by far the longest-serving director, serving until his death in 1972. In 1968, Congress passed legislation, as part of the Omnibus Crime Control and Safe Streets Act of 1968, requiring Senate confirmation of appointments of future Directors. As the incumbent, this legislation did not apply to Hoover. The last FBI Director was James B. Comey, who was appointed in 2013 by President Barack Obama. In 2017, he was fired by President Donald Trump.

The FBI director is responsible for the day-to-day operations at the FBI. Along with the Deputy Director, the director makes sure cases and operations are handled correctly. The director also is in charge of making sure the leadership in any one of the FBI field offices is manned with qualified agents. Before the Intelligence Reform and Terrorism Prevention Act was passed in the wake of the September 11 attacks, the FBI director would directly brief the President of the United States on any issues that arise from within the FBI. Since then, the director now reports to the Director of National Intelligence (DNI), who in turn reports to the President.

Firearms

A Glock 22 pistol in .40 S&W caliber
 
Upon qualification, an FBI special agent is issued a full-size Glock 22 or compact Glock 23 semi-automatic pistol, both of which are chambered in the .40 S&W cartridge. In May 1997, the FBI officially adopted the Glock, in .40 S&W, for general agent use, and first issued it to New Agent Class 98-1 in October 1997. At present, the Glock 23 "FG&R" (finger groove and rail; either 3rd generation or "Gen4") is the issue sidearm. New agents are issued firearms, on which they must qualify, on successful completion of their training at the FBI Academy. The Glock 26 (subcompact 9mm Parabellum), Glock 23 and Glock 27 (.40 S&W compact and subcompact, respectively) are authorized as secondary weapons. Special agents are also authorized to purchase and qualify with the Glock 21 in .45 ACP.

Special agents of the FBI Hostage Rescue Team (HRT) and regional SWAT teams are issued the Springfield Armory Professional Model 1911 pistol in .45 ACP.

In June 2016, the FBI awarded Glock a contract for new handguns. Unlike the currently issued .40 S&W chambered Glock pistols, the new Glocks will be chambered for 9mm Parabellum. The contract is for the full-size Glock 17M and the compact Glock 19M. The "M" means the Glocks have been modified to meet government standards specified by a 2015 government request for proposal.

Publications

The FBI Law Enforcement Bulletin is published monthly by the FBI Law Enforcement Communication Unit, with articles of interest to state and local law enforcement personnel. First published in 1932 as Fugitives Wanted by Police, the FBI Law Bulletin covers topics including law enforcement technology and issues, such as crime mapping and use of force, as well as recent criminal justice research, and Vi-CAP alerts, on wanted suspects and key cases.

The FBI also publishes some reports for both law enforcement personnel as well as regular citizens covering topics including law enforcement, terrorism, cybercrime, white-collar crime, violent crime, and statistics. However, the vast majority of federal government publications covering these topics are published by the Office of Justice Programs agencies of the United States Department of Justice, and disseminated through the National Criminal Justice Reference Service.

Crime statistics

In the 1920s, the FBI began issuing crime reports by gathering numbers from local police departments. Due to limitations of this system found during the 1960s and 1970s—victims often simply did not report crimes to the police in the first place—the Department of Justice developed an alternative method of tallying crime, the victimization survey.

Uniform Crime Reports

The Uniform Crime Reports (UCR) compile data from over 17,000 law enforcement agencies across the country. They provide detailed data regarding the volume of crimes to include arrest, clearance (or closing a case), and law enforcement officer information. The UCR focuses its data collection on violent crimes, hate crimes, and property crimes. Created in the 1920s, the UCR system has not proven to be as uniform as its name implies. The UCR data only reflect the most serious offense in the case of connected crimes and has a very restrictive definition of rape. Since about 93% of the data submitted to the FBI is in this format, the UCR stands out as the publication of choice as most states require law enforcement agencies to submit this data. 

Preliminary Annual Uniform Crime Report for 2006 was released on June 4, 2006. The report shows violent crime offenses rose 1.3%, but the number of property crime offenses decreased 2.9% compared to 2005.

National Incident-Based Reporting System

The National Incident-Based Reporting System (NIBRS) crime statistics system aims to address limitations inherent in UCR data. The system is used by law enforcement agencies in the United States for collecting and reporting data on crimes. Local, state, and federal agencies generate NIBRS data from their records management systems. Data is collected on every incident and arrest in the Group A offense category. The Group A offenses are 46 specific crimes grouped in 22 offense categories. Specific facts about these offenses are gathered and reported in the NIBRS system. In addition to the Group A offenses, eleven Group B offenses are reported with only the arrest information. The NIBRS system is in greater detail than the summary-based UCR system. As of 2004, 5,271 law enforcement agencies submitted NIBRS data. That amount represents 20% of the United States population and 16% of the crime statistics data collected by the FBI.

eGuardian

eGuardian is the name of an FBI system, launched in January 2009, to share tips about possible terror threats with local police agencies. The program aims to get law enforcement at all levels sharing data quickly about suspicious activity and people.

eGuardian enables near real-time sharing and tracking of terror information and suspicious activities with local, state, tribal, and federal agencies. The eGuardian system is a spin-off of a similar but classified tool called Guardian that has been used inside the FBI, and shared with vetted partners since 2005.

Media portrayal

The popular TV series The X-Files depicts the fictional FBI Special Agents Dana Scully (Gillian Anderson) and Fox Mulder (David Duchovny) who investigate paranormal phenomena.
 
The FBI has been frequently depicted in popular media since the 1930s. The bureau has participated to varying degrees, which has ranged from direct involvement in the creative process of film or TV series development, to providing consultation on operations and closed cases. A few of the notable portrayals of the FBI on television are the series The X-Files, which started in 1993 and concluded its eleventh season in early 2018, and concerned investigations into paranormal phenomena by five fictional Special Agents, and the fictional Counter Terrorist Unit (CTU) agency in the TV drama 24, which is patterned after the FBI Counterterrorism Division. The 1991 movie Point Break depicts an undercover FBI agent who infiltrated a gang of bank robbers. The 1997 movie Donnie Brasco is based on the true story of undercover FBI agent Joseph D. Pistone infiltrating the Mafia. The 2015 TV series Quantico, titled after the location of the Bureau's training facility, deals with Probationary and Special Agents, not all of whom, within the show's format, may be fully reliable or even trustworthy.

History of radio

From Wikipedia, the free encyclopedia

The early history of radio is the history of technology that produces and uses radio instruments that use radio waves. Within the timeline of radio, many people contributed theory and inventions in what became radio. Radio development began as "wireless telegraphy". Later radio history increasingly involves matters of broadcasting.

Summary

Invention

The idea of wireless communication predates the discovery of "radio" with experiments in "wireless telegraphy" via inductive and capacitive induction and transmission through the ground, water, and even train tracks from the 1830s on. James Clerk Maxwell showed in theoretical and mathematical form in 1864 that electromagnetic waves could propagate through free space. It is likely that the first intentional transmission of a signal by means of electromagnetic waves was performed in an experiment by David Edward Hughes around 1880, although this was considered to be induction at the time. In 1888 Heinrich Rudolf Hertz was able to conclusively prove transmitted airborne electromagnetic waves in an experiment confirming Maxwell's theory of electromagnetism.

After the discovery of these "Hertzian waves" (it would take almost 20 years for the term "radio" to be universally adopted for this type of electromagnetic radiation) many scientists and inventors experimented with wireless transmission, some trying to develop a system of communication, some intentionally using these new Hertzian waves, some not. Maxwell's theory showing that light and Hertzian electromagnetic waves were the same phenomenon at different wavelengths led "Maxwellian" scientist such as John Perry, Frederick Thomas Trouton and Alexander Trotter to assume they would be analogous to optical signaling and the Serbian American engineer Nikola Tesla to consider them relatively useless for communication since "light" could not transmit further than line of sight. In 1892 the physicist William Crookes wrote on the possibilities of wireless telegraphy based on Hertzian waves and in 1893 Tesla proposed a system for transmitting intelligence and wireless power using the earth as the medium. Others, such as Amos Dolbear, Sir Oliver Lodge, Reginald Fessenden, and Alexander Popov were involved in the development of components and theory involved with the transmission and reception of airborne electromagnetic waves for their own theoretical work or as a potential means of communication.

Over several years starting in 1894 the Italian inventor Guglielmo Marconi built the first complete, commercially successful wireless telegraphy system based on airborne Hertzian waves (radio transmission). Marconi demonstrated the application of radio in military and marine communications and started a company for the development and propagation of radio communication services and equipment.

19th century

The meaning and usage of the word "radio" has developed in parallel with developments within the field of communications and can be seen to have three distinct phases: electromagnetic waves and experimentation; wireless communication and technical development; and radio broadcasting and commercialization. In an 1864 presentation, published in 1865, James Clerk Maxwell proposed his theories and mathematical proofs on electromagnetism that showed that light and other phenomena were all types of electromagnetic waves propagating through free space. In 1886–88 Heinrich Rudolf Hertz conducted a series of experiments that proved the existence of Maxwell's electromagnetic waves, using a frequency in what would later be called the radio spectrum. Many individuals—inventors, engineers, developers and businessmen—constructed systems based on their own understanding of these and other phenomena, some predating Maxwell and Hertz's discoveries. Thus "wireless telegraphy" and radio wave-based systems can be attributed to multiple "inventors". Development from a laboratory demonstration to a commercial entity spanned several decades and required the efforts of many practitioners.

In 1878, David E. Hughes noticed that sparks could be heard in a telephone receiver when experimenting with his carbon microphone. He developed this carbon-based detector further and eventually could detect signals over a few hundred yards. He demonstrated his discovery to the Royal Society in 1880, but was told it was merely induction, and therefore abandoned further research. Thomas Edison came across the electromagnetic phenomenon while experimenting with a telegraph at Menlo Park. He noted an unexplained transmission effect while experimenting with a telegraph. He referred to this as etheric force in an announcement on November 28, 1875. Elihu Thomson published his findings on Edison's new "force", again attributing it to induction, an explanation that Edison accepted. Edison would go on the next year to take out U.S. Patent 465,971 on a system of electrical wireless communication between ships based on electrostatic coupling using the water and elevated terminals. Although this was not a radio system the Marconi Company would purchase the rights in 1903 to protect them legally from lawsuits.

Hertzian waves

Between 1886 and 1888 Heinrich Rudolf Hertz published the results of his experiments wherein he was able to transmit electromagnetic waves (radio waves) through the air, proving Maxwell's electromagnetic theory. Thus, given Hertz comprehensive discoveries, radio waves were referred to as "Hertzian waves". Between 1890 and 1892 physicists such as John Perry, Frederick Thomas Trouton and William Crookes proposed electromagnetic or Hertzian waves as a navigation aid or means of communication, with Crookes writing on the possibilities of wireless telegraphy based on Hertzian waves in 1892.

After learning of Hertz' demonstrations of wireless transmission, inventor Nikola Tesla began developing his own systems based on Hertz' and Maxwell's ideas, primarily working toward a means of wireless lighting, and power distribution. Tesla, concluding that Hertz had not demonstrated airborne electromagnetic waves (radio transmission), went on to develop a system based on what he thought was the primary conductor, the earth. In 1893 demonstrations of his ideas, in St. Louis, Missouri and at the Franklin Institute in Philadelphia, Tesla proposed this wireless power technology could also incorporate a system for the telecommunication of information.

In a lecture on the work of Hertz, shortly after his death, Professors Oliver Lodge and Alexander Muirhead demonstrated wireless signaling using Hertzian (radio) waves in the lecture theater of the Oxford University Museum of Natural History on August 14, 1894. During the demonstration radio waves were sent from the neighboring Clarendon Laboratory building, and received by apparatus in the lecture theater.

Building on the work of Lodge, the Bengali Indian physicist Jagadish Chandra Bose ignited gunpowder and rang a bell at a distance, using millimeter-range-wavelength microwaves, in a November 1894 public demonstration at the Town Hall of Kolkata, India. Bose wrote in a Bengali essay, "Adrisya Alok" ("Invisible Light"), "The invisible light can easily pass through brick walls, buildings etc. Therefore, messages can be transmitted by means of it without the mediation of wires." Bose's first scientific paper, "On polarisation of electric rays by double-refracting crystals" was communicated to the Asiatic Society of Bengal in May 1895.

Following that, Bose produced a series of articles in English, one after another. His second paper was communicated to the Royal Society of London by Lord Rayleigh in October 1895. In December 1895, the London journal The Electrician (Vol. 36) published Bose's paper, "On a new electro-polariscope". At that time, the word 'coherer', coined by Lodge, was used in the English-speaking world to mean Hertzian wave receivers or detectors. The Electrician (December 1895) readily commented on Bose's coherer. The Englishman (18 January 1896) quoted from The Electrician and commented as follows: "Should Professor Bose succeed in perfecting and patenting his ‘Coherer’, we may in time see the whole system of coast lighting throughout the navigable world revolutionised by an Indian Bengali scientist working single handed[ly] in our Presidency College Laboratory." Bose planned to "perfect his coherer", but never thought of patenting it.

In 1895, conducting experiments along the lines of Hertz's research, Alexander Stepanovich Popov built his first radio receiver, which contained a coherer. Popover further refined his invention as a lightning detector and presented to the Russian Physical and Chemical Society on May 7, 1895. A depiction of the lightning detector was printed in the Journal of the Russian Physical and Chemical Society the same year (publication of the minutes 15/201 of this session – December issue of the journal RPCS). An earlier description of the device was given by Dmitry Aleksandrovich Lachinov in July 1895 in the second edition of his course "Fundamentals of Meteorology and Climatology", which was the first such course in Russia. Popov's receiver was created on the improved basis of Lodge's receiver, and originally intended for reproduction of its experiments.

Marconi

British Post Office engineers inspect Guglielmo Marconi's wireless telegraphy (radio) equipment in 1897.
 
In 1894 the young Italian inventor Guglielmo Marconi began working on the idea of building a commercial wireless telegraphy system based on the use of Hertzian waves (radio waves), a line of inquiry that he noted other inventors did not seem to be pursuing. Marconi read through the literature and used the ideas of others who were experimenting with radio waves but did a great deal to develop devices such as portable transmitters and receiver systems that could work over long distances, turning what was essentially a laboratory experiment into a useful communication system. By August 1895 Marconi was field testing his system but even with improvements he was only able to transmit signals up to one-half mile, a distance Oliver Lodge had predicted in 1894 as the maximum transmission distance for radio waves. Marconi raised the height of his antenna and hit upon the idea of grounding his transmitter and receiver. With these improvements the system was capable of transmitting signals up to 2 miles (3.2 km) and over hills. Marconi's experimental apparatus proved to be the first engineering-complete, commercially successful radio transmission system. Marconi's apparatus is also credited with saving the 700 people who survived the tragic Titanic disaster.

In 1896, Marconi was awarded British patent 12039, Improvements in transmitting electrical impulses and signals and in apparatus there-for, the first patent ever issued for a Hertzian wave (radio wave) base wireless telegraphic system. In 1897, he established a radio station on the Isle of Wight, England. Marconi opened his "wireless" factory in the former silk-works at Hall Street, Chelmsford, England in 1898, employing around 60 people. Shortly after the 1900s, Marconi held the patent rights for radio. Marconi would go on to win the Nobel Prize in Physics in 1909 and be more successful than any other inventor in his ability to commercialize radio and its associated equipment into a global business. In the US some of his subsequent patented refinements (but not his original radio patent) would be overturned in a 1935 court case (upheld by the US Supreme Court in 1943).

20th century

In 1900, Brazilian priest Roberto Landell de Moura transmitted the human voice wirelessly. According to the newspaper Jornal do Comercio (June 10, 1900), he conducted his first public experiment on June 3, 1900, in front of journalists and the General Consul of Great Britain, C.P. Lupton, in São Paulo, Brazil, for a distance of approximately 5.0 miles (8 km). The points of transmission and reception were Alto de Santana and Paulista Avenue.

One year after that experiment, de Moura received his first patent from the Brazilian government. It was described as "equipment for the purpose of phonetic transmissions through space, land and water elements at a distance with or without the use of wires." Four months later, knowing that his invention had real value, he left Brazil for the United States with the intent of patenting the machine at the U.S. Patent Office in Washington, D.C.
 
Having few resources, he had to rely on friends to push his project. Despite great difficulty, three patents were awarded: "The Wave Transmitter" (October 11, 1904), which is the precursor of today's radio transceiver; "The Wireless Telephone" and the "Wireless Telegraph", both dated November 22, 1904. 

"The Wireless Telephone", U.S. Patent Office in Washington, D.C.
 
The next advancement was the vacuum tube detector, invented by Westinghouse engineers. On Christmas Eve 1906, Reginald Fessenden used a synchronous rotary-spark transmitter for the first radio program broadcast, from Ocean Bluff-Brant Rock, Massachusetts. Ships at sea heard a broadcast that included Fessenden playing O Holy Night on the violin and reading a passage from the Bible. This was, for all intents and purposes, the first transmission of what is now known as amplitude modulation or AM radio.

In June 1912 Marconi opened the world's first purpose-built radio factory at New Street Works in Chelmsford, England. 

The first radio news program was broadcast August 31, 1920 by station 8MK in Detroit, Michigan, which survives today as all-news format station WWJ under ownership of the CBS network. The first college radio station began broadcasting on October 14, 1920 from Union College, Schenectady, New York under the personal call letters of Wendell King, an African-American student at the school.

That month 2ADD (renamed WRUC in 1947), aired what is believed to be the first public entertainment broadcast in the United States, a series of Thursday night concerts initially heard within a 100-mile (160 km) radius and later for a 1,000-mile (1,600 km) radius. In November 1920, it aired the first broadcast of a sporting event. At 9 pm on August 27, 1920, Sociedad Radio Argentina aired a live performance of Richard Wagner's opera Parsifal from the Coliseo Theater in downtown Buenos Aires. Only about twenty homes in the city had receivers to tune in this radio program. Meanwhile, regular entertainment broadcasts commenced in 1922 from the Marconi Research Centre at Writtle, England. 

Sports broadcasting began at this time as well, including the college football on radio broadcast of a 1921 West Virginia vs. Pittsburgh football game.

One of the first developments in the early 20th century was that aircraft used commercial AM radio stations for navigation. This continued until the early 1960s when VOR systems became widespread. In the early 1930s, single sideband and frequency modulation were invented by amateur radio operators. By the end of the decade, they were established commercial modes. Radio was used to transmit pictures visible as television as early as the 1920s. Commercial television transmissions started in North America and Europe in the 1940s. 

In 1947 AT&T commercialized the Mobile Telephone Service. From its start in St. Louis in 1946, AT&T then introduced Mobile Telephone Service to one hundred towns and highway corridors by 1948. Mobile Telephone Service was a rarity with only 5,000 customers placing about 30,000 calls each week. Because only three radio channels were available, only three customers in any given city could make mobile telephone calls at one time. Mobile Telephone Service was expensive, costing US$15 per month, plus $0.30–0.40 per local call, equivalent to (in 2012 US dollars) about $176 per month and $3.50–4.75 per call. The Advanced Mobile Phone System analog mobile cell phone system, developed by Bell Labs, was introduced in the Americas in 1978, gave much more capacity. It was the primary analog mobile phone system in North America (and other locales) through the 1980s and into the 2000s.

The Regency TR-1, which used Texas Instruments' NPN transistors, was the world's first commercially produced transistor radio.
 
In 1954, the Regency company introduced a pocket transistor radio, the TR-1, powered by a "standard 22.5 V Battery." In 1955, the newly formed Sony company introduced its first transistorized radio. It was small enough to fit in a vest pocket, powered by a small battery. It was durable, because it had no vacuum tubes to burn out. Over the next 20 years, transistors replaced tubes almost completely except for high-power transmitters.

By 1963, color television was being broadcast commercially (though not all broadcasts or programs were in color), and the first (radio) communication satellite, Telstar, was launched. In the late 1960s, the U.S. long-distance telephone network began to convert to a digital network, employing digital radios for many of its links. In the 1970s, LORAN became the premier radio navigation system. 

Soon, the U.S. Navy experimented with satellite navigation, culminating in the launch of the Global Positioning System (GPS) constellation in 1987. In the early 1990s, amateur radio experimenters began to use personal computers with audio cards to process radio signals. In 1994, the U.S. Army and DARPA launched an aggressive, successful project to construct a software-defined radio that can be programmed to be virtually any radio by changing its software program. Digital transmissions began to be applied to broadcasting in the late 1990s.

Start of the 20th century

Around the start of the 20th century, the Slaby-Arco wireless system was developed by Adolf Slaby and Georg von Arco. In 1900, Reginald Fessenden made a weak transmission of voice over the airwaves. In 1901, Marconi conducted the first successful transatlantic experimental radio communications. In 1904, The U.S. Patent Office reversed its decision, awarding Marconi a patent for the invention of radio, possibly influenced by Marconi's financial backers in the States, who included Thomas Edison and Andrew Carnegie. This also allowed the U.S. government (among others) to avoid having to pay the royalties that were being claimed by Tesla for use of his patents. For more information see Marconi's radio work. In 1907, Marconi established the first commercial transatlantic radio communications service, between Clifden, Ireland and Glace Bay, Newfoundland.

Julio Cervera Baviera

Julio Cervera Baviera
 
Julio Cervera Baviera developed radio in Spain around 1902. Cervera Baviera obtained patents in England, Germany, Belgium, and Spain. In May–June 1899, Cervera had, with the blessing of the Spanish Army, visited Marconi's radiotelegraphic installations on the English Channel, and worked to develop his own system. He began collaborating with Marconi on resolving the problem of a wireless communication system, obtaining some patents by the end of 1899. Cervera, who had worked with Marconi and his assistant George Kemp in 1899, resolved the difficulties of wireless telegraph and obtained his first patents prior to the end of that year. On March 22, 1902, Cervera founded the Spanish Wireless Telegraph and Telephone Corporation and brought to his corporation the patents he had obtained in Spain, Belgium, Germany and England. He established the second and third regular radiotelegraph service in the history of the world in 1901 and 1902 by maintaining regular transmissions between Tarifa and Ceuta (across the Straits of Gibraltar) for three consecutive months, and between Javea (Cabo de la Nao) and Ibiza (Cabo Pelado). This is after Marconi established the radiotelegraphic service between the Isle of Wight and Bournemouth in 1898. In 1906, Domenico Mazzotto wrote: "In Spain the Minister of War has applied the system perfected by the commander of military engineering, Julio Cervera Baviera (English patent No. 20084 (1899))." Cervera thus achieved some success in this field, but his radiotelegraphic activities ceased suddenly, the reasons for which are unclear to this day.

British Marconi

Using various patents, the British Marconi company was established in 1897 and began communication between coast radio stations and ships at sea. This company, along with its subsidiaries Canadian Marconi and American Marconi, had a stranglehold on ship-to-shore communication. It operated much the way American Telephone and Telegraph operated until 1983, owning all of its equipment and refusing to communicate with non-Marconi equipped ships. In June 1912, after the RMS Titanic disaster, due to increased production Marconi opened the world's first purpose-built radio factory at New Street Works in Chelmsford, and in 1932 the Marconi Research Laboratory. Many inventions improved the quality of radio, and amateurs experimented with uses of radio, thus planting the first seeds of broadcasting.

Telefunken

The company Telefunken was founded on May 27, 1903, as "Telefunken society for wireless telefon" of Siemens & Halske (S & H) and the Allgemeine Elektrizitäts-Gesellschaft (General Electricity Company) as joint undertakings for radio engineering in Berlin. It continued as a joint venture of AEG and Siemens AG, until Siemens left in 1941. In 1911, Kaiser Wilhelm II sent Telefunken engineers to West Sayville, New York to erect three 600-foot (180-m) radio towers there. Nikola Tesla assisted in the construction. A similar station was erected in Nauen, creating the only wireless communication between North America and Europe.

Reginald Fessenden

The invention of amplitude-modulated (AM) radio, so that more than one station can send signals (as opposed to spark-gap radio, where one transmitter covers the entire bandwidth of the spectrum) is attributed to Reginald Fessenden and Lee de Forest. On Christmas Eve 1906, Reginald Fessenden used an Alexanderson alternator and rotary spark-gap transmitter to make the first radio audio broadcast, from Brant Rock, Massachusetts. Ships at sea heard a broadcast that included Fessenden playing O Holy Night on the violin and reading a passage from the Bible.

Ferdinand Braun

In 1909, Marconi and Karl Ferdinand Braun were awarded the Nobel Prize in Physics for "contributions to the development of wireless telegraphy".

Charles David Herrold

In April 1909 Charles David Herrold, an electronics instructor in San Jose, California constructed a broadcasting station. It used spark gap technology, but modulated the carrier frequency with the human voice, and later music. The station "San Jose Calling" (there were no call letters), continued to eventually become today's KCBS in San Francisco. Herrold, the son of a Santa Clara Valley farmer, coined the terms "narrowcasting" and "broadcasting", respectively to identify transmissions destined for a single receiver such as that on board a ship, and those transmissions destined for a general audience. (The term "broadcasting" had been used in farming to define the tossing of seed in all directions.) Charles Herrold did not claim to be the first to transmit the human voice, but he claimed to be the first to conduct "broadcasting". To help the radio signal to spread in all directions, he designed some omnidirectional antennas, which he mounted on the rooftops of various buildings in San Jose. Herrold also claims to be the first broadcaster to accept advertising (he exchanged publicity for a local record store for records to play on his station), though this dubious honour usually is foisted on WEAF (1922). 

RMS Titanic (April 2, 1912).
 
In 1912, the RMS Titanic sank in the northern Atlantic Ocean. After this, wireless telegraphy using spark-gap transmitters quickly became universal on large ships. In 1913, the International Convention for the Safety of Life at Sea was convened and produced a treaty requiring shipboard radio stations to be manned 24 hours a day. A typical high-power spark gap was a rotating commutator with six to twelve contacts per wheel, nine inches (229 mm) to a foot wide, driven by about 2,000 volts DC. As the gaps made and broke contact, the radio wave was audible as a tone in a magnetic detector at a remote location. The telegraph key often directly made and broke the 2,000 volt supply. One side of the spark gap was directly connected to the antenna. Receivers with thermionic valves became commonplace before spark-gap transmitters were replaced by continuous wave transmitters.

Harold J. Power

On March 8, 1916, Harold Power with his radio company American Radio and Research Company (AMRAD), broadcast the first continuous broadcast in the world from Tufts University under the call sign 1XE (it lasted 3 hours). The company later became the first to broadcast on a daily schedule, and the first to broadcast radio dance programs, university professor lectures, the weather, and bedtime stories.

Edwin Armstrong

Inventor Edwin Howard Armstrong is credited with developing many of the features of radio as it is known today. Armstrong patented three important inventions that made today's radio possible. Regeneration, the superheterodyne circuit and wide-band frequency modulation or FM. Regeneration or the use of positive feedback greatly increased the amplitude of received radio signals to the point where they could be heard without headphones. The superhet simplified radio receivers by doing away with the need for several tuning controls. It made radios more sensitive and selective as well. FM gave listeners a static-free experience with better sound quality and fidelity than AM.

Wavelength (meters) vs. frequency (kilocycles, kilohertz)

In early radio, and to a limited extent much later, the transmission signal of the radio station was specified in meters, referring to the wavelength, the length of the radio wave. This is the origin of the terms long wave, medium wave, and short wave radio. Portions of the radio spectrum reserved for specific purposes were often referred to by wavelength: the 40-meter band, used for amateur radio, for example. The relation between wavelength and frequency is reciprocal: the higher the frequency, the shorter the wave, and vice versa.

As equipment progressed, precise frequency control became possible; early stations often did not have a precise frequency, as it was affected by the temperature of the equipment, among other factors. Identifying a radio signal by its frequency rather than its length proved much more practical and useful, and starting in the 1920s this became the usual method of identifying a signal, especially in the United States. Frequencies specified in number of cycles per second (kilocycles, megacycles) were replaced by the more precise designation of hertz (cycles per second) about 1965.

Audio broadcasting (1919 to 1950s)

Crystal sets

In the 1920s, the United States government publication, "Construction and Operation of a Simple Homemade Radio Receiving Outfit", showed how almost any person handy with simple tools could a build an effective crystal radio receiver.
 
The most common type of receiver before vacuum tubes was the crystal set, although some early radios used some type of amplification through electric current or battery. Inventions of the triode amplifier, motor-generator, and detector enabled audio radio. The use of amplitude modulation (AM), with which more than one station can simultaneously send signals (as opposed to spark-gap radio, where one transmitter covers the entire bandwidth of spectra) was pioneered by Fessenden and Lee de Forest

The art and science of crystal sets is still pursued as a hobby in the form of simple un-amplified radios that 'runs on nothing, forever'. They are used as a teaching tool by groups such as the Boy Scouts of America to introduce youngsters to electronics and radio. As the only energy available is that gathered by the antenna system, loudness is necessarily limited.

The first vacuum tubes

During the mid-1920s, amplifying vacuum tubes (or thermionic valves in the UK) revolutionized radio receivers and transmitters. John Ambrose Fleming developed a vacuum tube diode. Lee de Forest placed a screen, added a "grid" electrode, creating the triode. The Dutch company Nederlandsche Radio-Industrie and its owner engineer, Hanso Idzerda, made the first regular wireless broadcast for entertainment from its workshop in The Hague on 6 November 1919. The company manufactured both transmitters and receivers. Its popular program was broadcast four nights per week on AM 670 meters, until 1924 when the company ran into financial troubles.

On 27 August 1920, regular wireless broadcasts for entertainment began in Argentina, pioneered by the group around Enrique Telémaco Susini, and spark gap telegraphy stopped. On 31 August 1920 the first known radio news program was broadcast by station 8MK, the unlicensed predecessor of WWJ (AM) in Detroit, Michigan. In 1922 regular wireless broadcasts for entertainment began in the UK from the Marconi Research Centre 2MT at Writtle near Chelmsford, England. Early radios ran the entire power of the transmitter through a carbon microphone. In the 1920s, the Westinghouse company bought Lee de Forest's and Edwin Armstrong's patent. During the mid-1920s, Amplifying vacuum tubes (US)/thermionic valves (UK) revolutionized radio receivers and transmitters. Westinghouse engineers developed a more modern vacuum tube.

Political interest in the United Kingdom

The British government and the state-owned postal services found themselves under massive pressure from the wireless industry (including telegraphy) and early radio adopters to open up to the new medium. In an internal confidential report from February 25, 1924, the Imperial Wireless Telegraphy Committee stated:
We have been asked 'to consider and advise on the policy to be adopted as regards the Imperial Wireless Services so as to protect and facilitate public interest.' It was impressed upon us that the question was urgent. We did not feel called upon to explore the past or to comment on the delays which have occurred in the building of the Empire Wireless Chain. We concentrated our attention on essential matters, examining and considering the facts and circumstances which have a direct bearing on policy and the condition which safeguard public interests.

Licensing of radio stations in the U.S.

  • Under the Radio Act of 1912, licensing was the authority of the United States Department of Commerce and Labor (after 1913, the Department of Commerce). There is no known comprehensive record of the stations licensed under this act. The department had no authority to withhold a license from anyone who requested one, and did not regulate frequencies or power.
  • Beginning in 1926, the Federal Radio Commission regulated radio use in the United States.
  • The Radio Act of 1927 gave the Federal Radio Commission the power to grant and deny licenses, and to assign frequencies and power levels for each licensee. In 1928 it began requiring licenses of existing stations and setting controls on who could broadcast from where on what frequency and at what power. Some stations could not obtain a license and ceased operations. There was no control of the content being broadcast.
  • The Communications Act of 1934 abolished the Federal Radio Commission and replaced it with the Federal Communications Commission, giving it authority over broadcast television, then the subject of experiments, and the new radio networks (and famously contributing to the breakup of the NBC Network for anti-trust reasons).

Licensed commercial public radio stations

The question of the 'first' publicly targeted licensed radio station in the U.S. has more than one answer and depends on semantics. Settlement of this 'first' question may hang largely upon what constitutes 'regular' programming.
  • It is commonly attributed to KDKA in Pittsburgh, Pennsylvania, which in October 1920 received its license and went on the air as the first US licensed commercial broadcasting station on November 2, 1920 with the presidential election results as its inaugural show, but was not broadcasting daily until 1921. (Their engineer Frank Conrad had been broadcasting from on the two call sign signals of 8XK and 8YK since 1916.) Technically, KDKA was the first of several already-extant stations to receive a 'limited commercial' license.
  • On February 17, 1919, station 9XM at the University of Wisconsin in Madison broadcast human speech to the public at large. 9XM was first experimentally licensed in 1914, began regular Morse code transmissions in 1916, and its first music broadcast in 1917. Regularly scheduled broadcasts of voice and music began in January 1921. That station is still on the air today as WHA.
  • On August 20, 1920 8MK, began broadcasting daily and was later claimed by famed inventor Lee De Forest as the first commercial station. 8MK was licensed to a teenager, Michael DeLisle Lyons, and financed by E. W. Scripps. In 1921 8MK changed to WBL and then to WWJ in 1922, in Detroit. It has carried a regular schedule of programming to the present and also broadcast the 1920 presidential election returns just as KDKA did. Inventor Lee DeForest claims to have been present during 8MK's earliest broadcasts, since the station was using a transmitter sold by his company.
  • The first station to receive a commercial license was WBZ, then in Springfield, Massachusetts. Lists provided to the Boston Globe by the U.S. Department of Commerce showed that WBZ received its commercial license on 15 September 1921; another Westinghouse station, WJZ, then in Newark, New Jersey, received its commercial license on November 7, the same day as KDKA did. What separates WJZ and WBZ from KDKA is the fact that neither of the former stations remain in their original city of license, whereas KDKA has remained in Pittsburgh for its entire existence.
  • 2XG: Launched by Lee De Forest in the Highbridge section of New York City, that station began daily broadcasts in 1916. Like most experimental radio stations, however, it had to go off the air when the U.S. entered World War I in 1917, and did not return to the air.
  • 1XE: Launched by Harold J. Power in Medford, Massachusetts, 1XE was an experimental station that started broadcasting in 1917. It had to go off the air during World War I, but started up again after the war, and began regular voice and music broadcasts in 1919. However, the station did not receive its commercial license, becoming WGI, until 1922.
  • 2XN, broadcasting from the City College of New York
  • 2ZK, broadcasting in New Rochelle, New York
  • WWV, the U.S. Government time service, which was believed to have started 6 months before KDKA in Washington, D.C. but in 1966 was transferred to Ft. Collins, Colorado.
  • WRUC, located on Union College in Schenectady, New York; was launched as W2XQ
  • WHA (AM), located at the University of Wisconsin–Madison, Madison, Wisconsin; was launched as 9XM.
  • KQV, one of Pittsburgh's five original AM stations, signed on as amateur station "8ZAE" on November 19, 1919, but did not receive a commercial license until January 9, 1922.
Outside the United States there are also claims for the first radio stations:
  • XWA, Marconi's broadcast station in Montreal, Canada, since 1919 (was CFCF, later CINW and shut down in February 2010)
  • On August 27, 1920 the Argentina Station started the first transmission from Coliseo Theatre at Buenos Aires, Argentina. Later that station received the name LOR Radio Argentina, and finally LR2 Radio Argentina. That station was in service until 31 December 1997 at 1110 kHz.
Broadcasting was not yet supported by advertising or listener sponsorship. The stations owned by manufacturers and department stores were established to sell radios and those owned by newspapers to sell newspapers and express the opinions of the owners. In the 1920s, radio was first used to transmit pictures visible as television. During the early 1930s, single sideband (SSB) and frequency modulation (FM) were invented by amateur radio operators. By 1940, they were established commercial modes. 

Westinghouse was brought into the patent allies group, which included General Electric, American Telephone and Telegraph, and Radio Corporation of America, and became a part owner of RCA. All radios manufactured by GE and Westinghouse were sold under the RCA name, 60% GE and 40% Westinghouse. ATT's Western Electric would build radio transmitters. The patent allies attempted to set up a monopoly, but they failed due to successful competition. Much to the dismay of the patent allies, several of the contracts for inventor's patents held clauses protecting "amateurs" and allowing them to use the patents. Whether the competing manufacturers were really amateurs was ignored by these competitors. 

These features arose:

FM and television start

In 1933, FM radio was patented by inventor Edwin H. Armstrong. FM uses frequency modulation of the radio wave to reduce static and interference from electrical equipment and the atmosphere. In 1937, W1XOJ, the first experimental FM radio station, was granted a construction permit by the US Federal Communications Commission (FCC). In the 1930s, regular analog television broadcasting began in some parts of Europe and North America. By the end of the decade there were roughly 25,000 all-electronic television receivers in existence worldwide, the majority of them in the UK. In the US, Armstrong's FM system was designated by the FCC to transmit and receive television sound.

FM in Europe

After World War II, FM radio broadcasting was introduced in Germany. At a meeting in Copenhagen in 1948, a new wavelength plan was set up for Europe. Because of the recent war, Germany (which did not exist as a state and so was not invited) was only given a small number of medium-wave frequencies, which were not very good for broadcasting. For this reason Germany began broadcasting on UKW ("Ultrakurzwelle", i.e. ultra short wave, nowadays called VHF) which was not covered by the Copenhagen plan. After some amplitude modulation experience with VHF, it was realized that FM radio was a much better alternative for VHF radio than AM. Because of this history FM Radio is still referred to as "UKW Radio" in Germany. Other European nations followed a bit later, when the superior sound quality of FM and the ability to run many more local stations because of the more limited range of VHF broadcasts were realized.

Later 20th century developments

In 1954 Regency introduced a pocket transistor radio, the TR-1, powered by a "standard 22.5V Battery". In 1960 Sony introduced their first transistorized radio, small enough to fit in a vest pocket, and able to be powered by a small battery. It was durable, because there were no tubes to burn out. Over the next twenty years, transistors displaced tubes almost completely except for picture tubes and very high power or very high frequency uses. 

In the early 1960s, VOR systems finally became widespread for aircraft navigation; before that, aircraft used commercial AM radio stations for navigation. (AM stations are still marked on U.S. aviation charts).

Color television and digital

  • 1953: NTSC compatible color television introduced in the US.
  • 1962: Telstar 1, the first communications satellite, relayed the first publicly available live transatlantic television signal.
  • Late 1960s: The US long-distance telephone network began to convert to a digital network, employing digital radios for many of its links.
  • 1970s: LORAN became the premier radio navigation system. Soon, the US Navy experimented with satellite navigation.
  • 1987: The GPS constellation of satellites was launched.
  • Early 1990s: Amateur radio experimenters began to use personal computers with audio cards to process radio signals.
  • 1994: The US Army and DARPA launched an aggressive successful project to construct a software radio that could become a different radio on the fly by changing software.
  • Late 1990s: Digital transmissions began to be applied to broadcasting.
  • 2015: The first all-digital radio transmitter, called Pizzicato, was introduced.

Telex on radio

Telegraphy did not go away on radio. Instead, the degree of automation increased. On land-lines in the 1930s, teletypewriters automated encoding, and were adapted to pulse-code dialing to automate routing, a service called telex. For thirty years, telex was the cheapest form of long-distance communication, because up to 25 telex channels could occupy the same bandwidth as one voice channel. For business and government, it was an advantage that telex directly produced written documents.

Telex systems were adapted to short-wave radio by sending tones over single sideband. CCITT R.44 (the most advanced pure-telex standard) incorporated character-level error detection and retransmission as well as automated encoding and routing. For many years, telex-on-radio (TOR) was the only reliable way to reach some third-world countries. TOR remains reliable, though less-expensive forms of e-mail are displacing it. Many national telecom companies historically ran nearly pure telex networks for their governments, and they ran many of these links over short wave radio.

Documents including maps and photographs went by radiofax, or wireless photoradiogram, invented in 1924 by Richard H. Ranger of Radio Corporation of America (RCA). This method prospered in the mid-20th century and faded late in the century.

Mobile phones

In 1947 AT&T commercialized the Mobile Telephone Service. From its start in St. Louis in 1946, AT&T then introduced Mobile Telephone Service to one hundred towns and highway corridors by 1948. Mobile Telephone Service was a rarity with only 5,000 customers placing about 30,000 calls each week. Because only three radio channels were available, only three customers in any given city could make mobile telephone calls at one time. Mobile Telephone Service was expensive, costing US$15 per month, plus $0.30–0.40 per local call, equivalent to (in 2012 US dollars) about $176 per month and $3.50–4.75 per call. The Advanced Mobile Phone System analog mobile cell phone system, developed by Bell Labs, was introduced in the Americas in 1978, gave much more capacity. It was the primary analog mobile phone system in North America (and other locales) through the 1980s and into the 2000s.

Broadcast and copyright

When radio was introduced in the early 1920s, many predicted it would kill the phonograph record industry. Radio was a free medium for the public to hear music for which they would normally pay. While some companies saw radio as a new avenue for promotion, others feared it would cut into profits from record sales and live performances. Many record companies would not license their records to be played over the radio, and had their major stars sign agreements that they would not perform on radio broadcasts.

Indeed, the music recording industry had a severe drop in profits after the introduction of the radio. For a while, it appeared as though radio was a definite threat to the record industry. Radio ownership grew from two out of five homes in 1931 to four out of five homes in 1938. Meanwhile, record sales fell from $75 million in 1929 to $26 million in 1938 (with a low point of $5 million in 1933), though the economics of the situation were also affected by the Great Depression.

The copyright owners were concerned that they would see no gain from the popularity of radio and the ‘free’ music it provided. Luckily, what they needed to make this new medium work for them already existed in previous copyright law. The copyright holder for a song had control over all public performances ‘for profit.’ The problem now was proving that the radio industry, which was just figuring out for itself how to make money from advertising and currently offered free music to anyone with a receiver, was making a profit from the songs. 

The test case was against Bamberger's Department Store in Newark, New Jersey in 1922. The store was broadcasting music throughout its store on the radio station WOR. No advertisements were heard, except at the beginning of the broadcast which announced "L. Bamberger and Co., One of America's Great Stores, Newark, New Jersey." It was determined through this and previous cases (such as the lawsuit against Shanley's Restaurant) that Bamberger was using the songs for commercial gain, thus making it a public performance for profit, which meant the copyright owners were due payment.

With this ruling the American Society of Composers, Authors and Publishers (ASCAP) began collecting licensing fees from radio stations in 1923. The beginning sum was $250 for all music protected under ASCAP, but for larger stations the price soon ballooned to $5,000. Edward Samuels reports in his book The Illustrated Story of Copyright that "radio and TV licensing represents the single greatest source of revenue for ASCAP and its composers […] and [a]n average member of ASCAP gets about $150–$200 per work per year, or about $5,000-$6,000 for all of a member's compositions." Not long after the Bamberger ruling, ASCAP had to once again defend their right to charge fees, in 1924. The Dill Radio Bill would have allowed radio stations to play music without paying and licensing fees to ASCAP or any other music-licensing corporations. The bill did not pass.
