Big Tech, also known as the Tech Giants, Big Four or Big Five, is a name given to the four or five largest, most dominant companies in the information technology industry of the United States. The Big Four presently consists of Alphabet (Google), Amazon, Apple, and Meta (Facebook)—with Microsoft completing the Big Five. Broader groupings of Big Tech may also include Twitter, Netflix, and Tesla. Companies like Tencent and Alibaba Group serve as the equivalents of Big Tech in Asian regions.

The tech giants are the dominant players in their respective areas of technology, namely: e-commerce, online advertising, consumer electronics, cloud computing, computer software, media streaming, artificial intelligence, smart home, self-driving cars, and social networking. They have been among the most valuable public companies globally, each having had a maximum market capitalization ranging from around $1 trillion to above $3 trillion. They are additionally considered to be among the most prestigious and selective employers in the world, especially Google.

Big Tech companies typically offer services to millions of users, and thus can hold sway on user behavior as well as control of user data. Concerns over monopolistic practices have led to antitrust investigations from the Department of Justice and Federal Trade Commission in the United States, and the European Commission. Commentators have questioned the impact of these companies on privacy, market power, free speech, censorship, national security and law enforcement. It has been speculated that it may not be possible to live in the digital world day-to-day outside of the ecosystem created by the companies.

The concept of Big Tech is analogous to the consolidation of market dominance by a few companies in other market sectors such as "Big Oil" and "Big Media". "Big Tech" may also refer to historical versions of this concept, with the likes of Microsoft, IBM and AT&T considered to be dominant companies in this industry in the mid to late 20th century.

Origin

The idea of "big" technology companies had entered the public consciousness around 2013, as some economists saw signs of these companies gaining appreciable dominance without any regulation, and were no longer considered disruptive start-up companies following the early 2000s dot-com bubble. The term became popularized and labeled as "Big Tech" around 2017 in the wake of the investigation into possible Russian interference in the 2016 United States elections, as the roles that these technology companies has played with access to wide amounts of user data or big data and ability to influence their users came under Congressional review. The use of "Big Tech" was similar to how the largest oil companies were grouped under Big Oil following the 1970s energy crisis, or how the major cigarette producers were grouped as Big Tobacco as Congress began seeking regulation on that industry, or how, at the turn of the 21st century, the global commercial media system came to be dominated by a small number (around nine or ten) of extremely powerful and mainly U.S.-based transnational media corporations called collectively the "Big Media" or global "Media Giants".

Membership and definitions

The term Big Tech is often broken down into more specific sub-groupings, often referred to by the following names or acronyms. Alphabet Inc., the parent company of Google, may be represented as a "G" in these acronyms, while Meta Platforms, the rebranding of Facebook, Inc., may be represented by "F".

Big Four

Google (Alphabet), Amazon, Facebook (Meta), and Apple are commonly referred to as Big Four or GAMA. They have also been referred to as "The Four", "Gang of Four", and as the "Four Horsemen". The GAMA were known as GAFA before Facebook rebranded its name to Meta in 2021.

Former Google CEO Eric Schmidt, author Phil Simon, and NYU professor Scott Galloway have each grouped these four companies together, on the basis that those companies have driven major societal change via their dominance and role in online activities. This is unlike other large tech companies such as Microsoft and IBM, according to Simon and Galloway. In 2011, Eric Schmidt excluded Microsoft from the grouping, saying "Microsoft is not driving the consumer revolution in the minds of the consumers."

Big Five

A more inclusive grouping, referred to as Big Five or GAMAM defines Google, Amazon, Meta, Apple, and Microsoft as the tech giants.

Besides Saudi Aramco, the GAMAM companies were the five most valuable public corporations in the world in January 2020 as measured by market capitalization. The GAMAM were known as GAFAM before Facebook rebranded its name to Meta in 2021.

FANG, FAANG, and MAMAA

FANG was an acronym coined by Jim Cramer, the television host of CNBC's Mad Money, in 2013 to refer to Facebook, Amazon, Netflix, and Google. Cramer called these companies "totally dominant in their markets". Cramer considered that the four companies were poised "to really take a bite out of" the bear market, giving double meaning to the acronym, according to Cramer's colleague at RealMoney.com, Bob Lang.

Cramer expanded FANG to FAANG in 2017, adding Apple to the other four companies due to its revenues placing it as a potential Fortune 50 company. Following Facebook, Inc.'s name change to Meta Platforms Inc. in October 2021, Cramer suggested replacing FAANG with MAMAA; this included replacing Netflix with Microsoft among the five companies represented as Netflix's valuation had not kept up with the other companies included in his acronym; with Microsoft, these new five companies each had market caps of at least $900 billion compared to Netflix's $310 billion at the time of Meta's rebranding.

In November 2021, The Motley Fool parodied MAMAA and FAANG by coming up with the acronym MANAMANA, which includes Microsoft, Apple, Netflix, Alphabet, Meta, Amazon, Nvidia, and Adobe.

Other companies

Although smaller in market capitalization, Netflix, Twitter, Snap, and Uber are sometimes referred to as "Big Tech" due to their popular influence. Twitter being categorized as Big Tech has featured in political debates and economic commentary due to perceived political and social influence of the platform.

There were also two Chinese technology companies in the top ten most valuable publicly traded companies globally at the end of the 2010s – Alibaba and Tencent. Smyrnaios argued in 2016 that the Asian giant corporations Samsung, Alibaba, Baidu, and Tencent could or should be included in the definition. Baidu, Alibaba, Tencent and Xiaomi, collectively referred to as BATX, are often seen as the competitor companies of Big Tech in China's technology sector. ByteDance has also been considered Big Tech. Together, the combination of the Big Five, IBM, Alibaba, Baidu and Tencent has been referred to as "G-MAFIA + BAT".

Tesla

Automaker Tesla has frequently been deemed one of the Big Tech companies, though its inclusion is subject to wide debate. Opponents to its designation as a tech company include Stephen Wilmot, a correspondent for The Wall Street Journal, who raises concerns regarding the supply chain, especially raw materials, semiconductor shortages, and the price of electric vehicle batteries. Business Insider concurs, stating that because Tesla makes more cars, it should be classified as an automaker and should aspire to be more like Honda. In support of the designation include Al Root of Barron's, who argues while Tesla isn't a good tech company due to factors of the car market, but regardless still a tech company. Fortune also designated Tesla as a tech company when reporting Big Tech's 2022 Q1 earnings, and The Washington Post argues that Tesla's vehicles are comparable to Apple's iPhone and its walled garden ecosystem.

Market dominance

The 10 largest corporations by market capitalization

The tech giants have replaced the energy giants such as ExxonMobil, BP, Gazprom, PetroChina, Chevron, and Shell ("Big Oil") from the first decade of the 21st century at the top of the NASDAQ stock index. They have also outpaced the traditional big media companies such as Disney, Warner Bros. Discovery, and Comcast by a factor of 10. In 2017, the five biggest American IT companies had a combined valuation of over $3.3 trillion, and made up more than 40 percent of the value of the Nasdaq 100. It has been observed that the companies remain popular by providing some of their services to consumers for free.

Alphabet (Google)

Google is the leader in online search (Google Search), online video sharing (YouTube), email services (Gmail), web browsing (Google Chrome) and online mapping-based navigation (Google Maps and Waze), mobile operating systems (Android) and online storage (Google Drive) as well as a variety of other popular tech services. Google Cloud is the third largest player in the cloud computing market after Amazon and Microsoft. Google and Facebook hold a duopoly over the digital advertising market. Google's advertising business makes up 82% of its revenues and most of its profit.

Alphabet has emerged among tech firms as the global leader in AI/ML, autonomous vehicles, and quantum computing. Waymo, Alphabet's self-driving car subsidiary, is considered to be the leader in autonomous vehicle technology and was the first self-driving company to offer a publicly available robo-taxi service in 2021. With its Sycamore processor, Google is seen as the leader in quantum computing and in 2019, it claimed Sycamore had achieved quantum supremacy.

Amazon

By 2017, Amazon was the dominant market leader in e-commerce with 40.4% market share; cloud computing, with nearly 32% market share, and live-streaming with Twitch owning 75.6% market share. With Amazon Alexa and Echo, Amazon is additionally the market leader in the area of artificial intelligence-based personal digital assistants and smart speakers (Amazon Echo) with 69% market share followed by Google (Google Nest) at 25% market share.

Amazon Web Services made up 59% of the Amazon's profit in 2020, and more than half of the company's profit every year since 2014. Following the development of EC2 by Amazon in 2006, Google and Microsoft followed in 2008 with Google App Engine (expanded to Google Cloud Platform since 2011) and Windows Azure (Microsoft Azure since 2010).

Apple

Apple sells high-margin smartphones and other consumer electronics devices, sharing a duopoly with Google in the field of mobile operating systems: 27% of the market share belonging to Apple (iOS) and 72% to Google (Android).

Meta (Facebook)

Meta Platforms, formerly Facebook, Inc. until its rebranding in October 2021, is the parent company of the Facebook social network, as well as owner of the Instagram online image sharing service and WhatsApp online messaging service.

Facebook had acquired Oculus in 2014, entering the virtual reality market.

Microsoft

Microsoft continues to dominate in desktop operating system market share (Microsoft Windows) and in office productivity software (Microsoft Office). Microsoft is also the second biggest company in the cloud computing industry (Microsoft Azure), after Amazon, and is also one of the biggest players in the video game industry (Xbox). Microsoft is also the dominant player in enterprise software (Microsoft 365, also available for consumers), and business collaboration suite (Microsoft Teams).

Causes

Smyrnaios argued in 2016 that four characteristics were key in the emergence of GAMA: the theory of media and information technology convergence, financialization, economic deregulation and globalization. He argued that the promotion of technology convergence by people such as Nicholas Negroponte made it appear credible and desirable for the Internet to evolve into an oligopoly. Autoregulation and the difficulty of politicians to understand software issues made governmental intervention against monopolies ineffective. Financial deregulation led to GAFA's big profit margins (all four except for Amazon had about 20–25 percent profit margins in 2014 according to Smyrnaios).

Innovation

A major contributing factor towards the growth of Big Tech is Section 230 of the Communications Decency Act, passed into law in 1996. Section 230 removed the liability for online services from hosting user-generated content that is deemed illegal, providing them safe harbor as long as they acted on such material when discovered in good faith. This allowed service providers in the early days of the Internet to expand offerings without having to invest heavily into content moderation. For this reason, Section 230 is often called "The twenty-six words that created the Internet", as it helped to fuel innovation in online services over the years that allowed Big Tech companies to grow and flourish.

"For decades, whole regions, nations even, have tried to model themselves on a particular ideal of innovation, the lifeblood of the modern economy. From Apple to Facebook, Silicon Valley’s freewheeling ecosystem of new, nimble corporations created massive wealth and retilted the world’s economic axis." The tech giants began as small engineering-focused firms building new products when their larger competitors were less innovative (such as Xerox when Apple was founded in 1976). The companies engaged in timely investment in rising technologies of the personal computer era, dotcom era, e-commerce, rise of mobile devices, social media, and cloud computing. The characteristics of these technologies allowed the companies to expand quickly with market adoption. According to Alexis Madrigal, the style of innovation that initially drove Silicon Valley firms to grow is being lost, shifting to a form of growing through acquisitions. Additionally, large companies tend to focus on process improvements rather than new products. However, the Big Tech firms all rank near the top on the list of companies by research and development spending.

"Cloud wars" between the tech giants have been observed as a major factor over the years, as the companies have competed on developing more efficient cloud computing services.

Among those who believe that acquisitions will weaken an original innovative atmosphere is scholar Tim Wu, Wu pointed out that when Meta acquired Instagram, it simply eliminated a competitive threat that may have presented a fresher competitor had it remained independent. He also states however that when Microsoft first emerged, with its innovations in personal computing and operating systems, it created platforms for new innovations by others. Wu formulated the idea of oligopoly "kill zones" created by acquiring competitors that approach their market. Big Tech operating in digital markets and being inherently focused on technology mean that Big Tech is more likely to focus on innovation than other groups of large industry dominating corporations before them. According to a report by the think tank ITIF, acquisitions being possible supports innovation, arguing the larger firm is less likely to simply copy the process of the smaller firm.

Globalization

According to Smyrnaios, globalization has allowed GAMAM to minimize its global taxation load and pay international workers much lower wages than would be required in the United States.

Oligopoly maintenance

Smyrnaios argued in 2016 that GAMA combines six vertical levels of power, data centers, internet connectivity, computer hardware including smartphones, operating systems, Web browsers and other user-level software, and online services. He also discussed horizontal concentration of power, in which diverse services such as email, instant messaging, online searching, downloading and streaming are combined internally within any of the GAMA members. For example, Google and Microsoft pay to have their web search engines appear as first and second in Apple's iPhone.

According to The Economist, "Network and scale effects mean that size begets size, while data can act as a barrier to entry."

Capitalism

The 2020 American docudrama film The Social Dilemma argues that capitalism is the root cause of Big Tech's harmful practices.

Antitrust legislation and investigations

United States

In the United States, antitrust scrutiny and investigations of members of Big Tech began in the late 1990s and early 2000s, leading to the first major American antitrust law case against a member of Big Tech in 2001 when the U.S. government accused Microsoft of illegally maintaining its monopoly position in the personal computer (PC) market primarily through the legal and technical restrictions it put on the abilities of PC manufacturers (OEMs) and users to uninstall Internet Explorer and use other programs such as Netscape and Java. At trial, the district court ruled that Microsoft's actions constituted unlawful monopolization under Section 2 of the Sherman Antitrust Act of 1890, and the U.S. Court of Appeals for the D.C. Circuit affirmed most of the district court's judgments. The DOJ later announced on September 6, 2001, that it was no longer seeking to break up Microsoft and would instead seek a lesser antitrust penalty in exchange for a settlement by Microsoft in which Microsoft agreed to share its application programming interfaces with third-party companies and appoint a panel of three people who would have full access to Microsoft's systems, records, and source code for five years in order to ensure compliance. On November 1, 2002, Judge Kollar-Kotelly released a judgment accepting most of the proposed DOJ settlement and on June 30, 2004, the U.S. appeals court unanimously approved the settlement with the Justice Department.

In the late 2010s and early 2020s the Big Tech industry again became the center of antitrust attention from the United States Department of Justice and the United States Federal Trade Commission that included requests to provide information about prior acquisitions and potentially anticompetitive practices. Some Democratic candidates running for president proposed plans to break up Big Tech companies and regulate them as utilities. "The role of technology in the economy and in our lives grows more important every day," said FTC Chairman Joseph Simons. "As I’ve noted in the past, it makes sense for us to closely examine technology markets to ensure consumers benefit from free and fair competition."

The United States House Judiciary Subcommittee on Antitrust, Commercial and Administrative Law began investigating Big Tech on an antitrust basis in June 2020, and published a report in January 2021 concluding that Apple, Amazon, Meta, and Google each operating in antitrust manners that requires some type of corrective action that either could be implemented through Congressional action or through legal actions taken by the Department of Justice, including the option of splitting up these companies.

On June 24, 2021 the United States House Judiciary Subcommittee on Antitrust, Commercial and Administrative Law held hearings on earlier introduced bills which would limit the scope of Big Tech. Among those bills was HR 3825, Ending Platform Monopolies Act introduced by Representative Pramila Jayapal which passed through the committee. The specific purpose of the bill is to prohibit platform holders to also compete in those same platforms. For example, Amazon attempted to purchase Diapers.com and when they resisted and refused to sell, Amazon started selling diaper related products at a loss which Diapers.com could not sustain. Amazon being the platform owner as well a player in the platform could easily sustain continued loss. The point came when Diapers.com could not sustain and they eventually, without any other choice ended up selling to Amazon out of fear even though Walmart was willing to pay more.

The issue of consumer welfare arose in the subcommittee but was voted down and rejected as the majority held the opinion that the reason we have these monopolies today is mainly because of the consumer welfare standard. This doctrine was introduced over 100 years ago and the committee would not adopt the consumer welfare standard in HR 3825.

The consumer welfare doctrine is an ideology which states that if the consumer enjoys lower pricing as a result of corporate mergers or decision making then those actions are not generally antitrust, no matter if there has been any damage done to the market or society. The newly appointed chair to the FTC, Lina Khan has held different views as outlined in her publication Amazon's Antitrust Paradox.

The recently introduced bills show that we will eventually drop or diminish the consumer welfare standard and move towards a marketplace welfare standard which promotes competition and levels the playing field for startups and businesses which have not fully grown.

There has been opposition from Big Tech regarding these bills and any legislation to trim them. Mark Zuckerberg of Meta implied that his company's success is important to the national security of the United States. Tim Cook, CEO of Apple spoke to House Speaker, Nancy Pelosi in an attempt to slow down the bills.

The spirit of the antitrust law is to protect consumers from the anticompetitive behavior of businesses that have either monopoly power in their market or companies that have banded together to exert cartel market behavior. Monopoly or cartel collusion creates market disadvantages for consumers. However, the antitrust law clearly distinguishes between purposeful monopolies and businesses that found themselves in a monopoly position purely as the result of business success. The purpose of the antitrust law is to stop businesses from deliberately creating monopoly power.

Consumer welfare, not assumptions that large firms are automatically harmful to competition, should be the core consideration of any antitrust action. The consumer welfare standard serves as the "good reason" in antitrust enforcement as it appropriately looks at the impact on consumers and economic efficiency. So far, it is not apparent that there has been a harm to consumer welfare and many technology companies continue to innovate and are bringing real benefits to consumers. At the same time, some Big Tech companies engage in "per se" uncompetitive conduct, such as Amazon Marketplace and Amazon Home Services, via scaled agreements that restrain free trade in violation of, inter alia, 18 U.S.C. § 1343; 15 U.S.C. § 1; 15 U.S.C. § 45. When agreements that restrain trade are scaled on the Internet, such acts can be reasonably prosecuted with criminal charges of multiple counts of wire fraud as an illegal activity that crosses interstate borders.

On July 9, 2021, President Joe Biden signed Executive Order 14036, "Promoting Competition in the American Economy", a sweeping array of initiatives across the executive branch. Related to Big Tech, the order established an executive branch-wide policy to more thoroughly scrutinize mergers involving Big Tech companies, with focus on the acquisition of new, potentially disruptive technology from smaller firms by the larger companies. The order also instructed the FTC to establish rules related to data collection and its use by Big Tech companies in promoting their own service.

European Union

The European Commission, which has imposed sanctions on several of the high tech giants.

In June 2020, the European Union opened two new antitrust investigations into practices by Apple. The first investigation focuses on issues including whether Apple is using its dominant position in the market to stifle competition using its music and book streaming services. The second investigation focuses on Apple Pay, which allows payment by Apple devices to brick and mortar vendors. Apple limits the ability of banks and other financial institutions to use the iPhones' near field radio frequency technology.

Fines are insufficient to deter anti-competitive practices by high tech giants, according to European Commissioner for Competition Margrethe Vestager. Commissioner Vestager explained, "fines are not doing the trick. And fines are not enough because fines are a punishment for illegal behaviour in the past. What is also in our decision is that you have to change for the future. You have to stop what you're doing."

In September 2021, the United States and European Union began discussions of a joint approach to Big Tech regulation. The European Parliament reached an agreement to implement the Digital Markets Act in March 2022, which once it has been implemented by member states, would restrict what data Big Tech companies could collect from European users, require interoperability of social media messaging applications, and allow alternate app stores and payment systems for systems like Apple and Google. The EU also reached agreement to implement the Digital Services Act in April 2022, which would require tech companies to take steps to remove illegal content from their services, such as hate speech and child sexual abuse, and eliminate targeting of ads based on gender, race or religion as well as targeting ads at children. Both the Digital Markets Act and Digital Services Act were enacted by the EU in July 2022.

Opposition

Scott Galloway has criticized the companies for "avoid[ing] taxes, invad[ing] privacy, and destroy[ing] jobs", while Smyrnaios has described the group as an oligopoly, coming to dominate the online market through anti-competitive practices, ever-increasing financial power, and intellectual property law. He has argued that the current situation is the result of economic deregulation, globalization, and the failure of politicians to understand and respond to developments in technology.

Smyrnaios recommended developing academic analysis of the political economy of the Internet in order to understand the methods of domination and to criticize these methods in order to encourage opposition to that domination.

Use of externally generated content

On May 9, 2019, the Parliament of France passed a law intended to force GAMA to pay for related rights (the reuse of substantial amounts of text, photos or videos), to the publishers and news agencies of the original materials. The law is aimed at implementing Article 15 of the Directive on Copyright in the Digital Single Market of the European Union.

Political debates

According to The Globe and Mail, criticism of Big Tech has come from both the left (progressives) and the right (conservatives). The Left has criticized Big Tech for "runaway profit-taking and concentration of wealth", while the Right has criticized Big Tech for having a "liberal bias". According to The New York Times, "The left generally argues that companies like Facebook and Twitter aren't doing enough to root out misinformation, extremism and hate on their platforms, while the right insists that tech companies are going so overboard in their content decisions that they're suppressing conservative political views." According to The Hill, libertarians are against government regulation of Big Tech due to their support for laissez-faire economics.

Accusations of inaction towards misinformation

Following Russian interference in the 2016 US election, Facebook was criticized for not doing enough to curb misinformation, and accused of downplaying its role in allowing misinformation to spread. Part of the controversy involved the Cambridge Analytica scandal and political data collection. In 2019, a Senate Intelligence Committee report criticized tech giants more generally for not responding strongly enough to misinformation, most Senate Intelligence reports regarding the subject focused on Meta and Twitter's role. 'Big tech' social media networks improved their response to fake accounts and influence operation trolls, and these initiatives received some praise compared to 2016.

In 2020 and 2021, social media giants have been frequently criticized for allowing COVID-19 misinformation to spread. According to Representatives Frank Pallone, Mike Doyle, and Jan Schakowsky, "Industry self-regulation has failed. We must begin the work of changing incentives driving social media companies to allow and even promote misinformation and disinformation." President Joe Biden criticized Facebook for allowing anti-vaccine propaganda to spread. Multiple social media platforms introduced more stringent moderation of health-related misinformation.

Human Rights Watch criticized Big Tech, primarily Meta's Facebook, for capturing the information market in developing countries where misinformation would rapidly spread to new internet users.

Accusations of censorship and election interference

The practice of banning of what is known as "hate speech" has also received public criticism as many of the targets tend to be conservatives. In July 2020, United States House Judiciary Subcommittee on Antitrust, Commercial and Administrative Law held a congressional hearing of CEOs of Alphabet, Amazon, Apple and Facebook, where some members of the subcommittee raised concerns about alleged bias against conservatives on social media. U.S. Representative for Florida's 1st congressional district Matt Gaetz suggested that the CEO of Amazon Jeff Bezos should "divorce from the SPLC," due to the practice of forbidding donations to organizations which are designated as hate groups by the SPLC.

On November 5, 2020, U. S. President Donald Trump claimed "historic election interference from big money, big media and big tech" and labeled the Democratic Party as "party of the big donors, the big media, the big tech". Conservative paper Washington Times criticized Trump's claim of election fraud as without evidence. On January 6, 2021, during his speech before the crowd of protesters stormed the United States Capitol, Trump accused "Big Tech" of rigging elections and shadow banning conservatives, while promising to hold them accountable and work to "get rid of" Section 230. On January 11, after Trump's Twitter account was suspended, German Chancellor Angela Merkel's chief spokesman Steffen Seibert noted that Merkel found Twitter's halt of Trump's account "problematic", adding that legislators, not private companies, should decide on any necessary curbs to free expression if speech incites to violence.

According to a New York University report in February 2021, conservative claims of social media censorship could be a form of disinformation, since an analysis of available data indicated that the claims that right-wing views were censored was false. Nonetheless, the same report also recommended that social media platforms could be more transparent to assuage concerns of ideological censorship, even if those concerns are overblown. However, conservatives have argued that Facebook and Twitter limiting the spread of the Hunter Biden laptop controversy on their platforms that later turned out to be accurate "proves Big Tech's bias". There is also a fear of over-censoring. One example is the ban of the channel Right Wing Watch by YouTube, which was banned for showing far-right content with the explicit goal of exposing and warning about those views (the channel was later restored after a backlash). Separately, Human Rights Watch stated that, particularly on Facebook, excessive content removals meant the loss of important information such as the documentation of human rights abuses needed as evidence to serve justice.

Facebook is also accused of censoring progressive voices, like deleting political ads by Democratic senator Elizabeth Warren who called for increased regulation of Big Tech monopolists and for breaking up Facebook because of its monopoly and abuse of power. Warren accused the company of having the "ability to shut down a debate" and called for "a social media marketplace that isn't dominated by a single censor".

Russian opposition figure Alexei Navalny criticized tech giants (specifically Apple and Google) for cooperating with a Russian government order to ban the Smart Voting app. In India, Facebook and Twitter were criticized for censoring social media in favour of the Indian government during the 2020–2021 Indian farmers' protest. The Wall Street Journal pointed out how Facebook regularly restricted content critical of the Indian government, but never any content by government supporters, no matter how false their claims.

Censorship against tech giants

The largest tech platforms have faced censorship themselves. Google have been banned in China since 2010, when they decided to leave the country after the Communist Party demanded censorship of search results. although an attempt at establishing Google China was made. Meta and Twitter have been banned in China since 2009. Microsoft's LinkedIn has been blocked in Russia since 2016. Russia also blocked access to Facebook and Twitter because of "disinformation" and "fake news" in 2022.

On March 21, 2022, Russia recognized Meta as an extremist organization, making Meta the first public company to be recognized as extremist in Russia.

Alternatives

Alt-tech is a group of websites, social media platforms, and Internet service providers that consider themselves alternatives to more mainstream offerings. In the 2010s and 2020s, some conservatives who were banned from other social media platforms, and their supporters, began to move toward alt-tech platforms. Alt-tech platforms have been criticized by researchers and journalists for providing a cover for far-right userbases and antisemitism.

Distributed social networks such as the fediverse, for microblogging based on the ActivityPub protocol, are decentralised networks, typically based on free and open-source software (FOSS) that aim at community moderation of content. In 2018, the fediverse was "a loose family of sites that promote unfettered interaction across servers or even services", intended to provide an alternative to the "walled gardens" of Big Tech social networks.

Industrial gas

From Wikipedia, the free encyclopedia
 
A gas regulator attached to a nitrogen cylinder.

Industrial gases are the gaseous materials that are manufactured for use in industry. The principal gases provided are nitrogen, oxygen, carbon dioxide, argon, hydrogen, helium and acetylene, although many other gases and mixtures are also available in gas cylinders. The industry producing these gases is also known as industrial gas, which is seen as also encompassing the supply of equipment and technology to produce and use the gases. Their production is a part of the wider chemical Industry (where industrial gases are often seen as "specialty chemicals").

Industrial gases are used in a wide range of industries, which include oil and gas, petrochemicals, chemicals, power, mining, steelmaking, metals, environmental protection, medicine, pharmaceuticals, biotechnology, food, water, fertilizers, nuclear power, electronics and aerospace. Industrial gas is sold to other industrial enterprises; typically comprising large orders to corporate industrial clients, covering a size range from building a process facility or pipeline down to cylinder gas supply.

Some trade scale business is done, typically through tied local agents who are supplied wholesale. This business covers the sale or hire of gas cylinders and associated equipment to tradesmen and occasionally the general public. This includes products such as balloon helium, dispensing gases for beer kegs, welding gases and welding equipment, LPG and medical oxygen.

Retail sales of small scale gas supply are not confined to just the industrial gas companies or their agents. A wide variety of hand-carried small gas containers, which may be called cylinders, bottles, cartridges, capsules or canisters are available to supply LPG, butane, propane, carbon dioxide or nitrous oxide. Examples are Whipped-cream chargers, powerlets, campingaz and sodastream.

Early history of gases

Blowing air at a spark

The first gas from the natural environment used by humans was almost certainly air when it was discovered that blowing on or fanning a fire made it burn brighter. Humans also used the warm gases from a fire to smoke foods and steam from boiling water to cook foods.

Bubbles of carbon dioxide form a froth on fermenting liquids such as beer

Carbon dioxide has been known from ancient times as the byproduct of fermentation, particularly for beverages, which was first documented dating from 7000–6600 B.C. in Jiahu, China. Natural gas was used by the Chinese in about 500 B.C. when they discovered the potential to transport gas seeping from the ground in crude pipelines of bamboo to where it was used to boil sea water. Sulfur dioxide was used by the Romans in winemaking as it had been discovered that burning candles made of sulfur inside empty wine vessels would keep them fresh and prevent them gaining a vinegar smell.

Early understanding consisted of empirical evidence and the protoscience of alchemy; however with the advent of scientific method and the science of chemistry, these gases became positively identified and understood.

The history of chemistry tells us that a number of gases were identified and either discovered or first made in relatively pure form during the Industrial Revolution of the 18th and 19th centuries by notable chemists in their laboratories. The timeline of attributed discovery for various gases are carbon dioxide (1754), hydrogen (1766), nitrogen (1772), nitrous oxide (1772), oxygen (1773), ammonia (1774), chlorine (1774), methane (1776), hydrogen sulfide (1777), carbon monoxide (1800), hydrogen chloride (1810), acetylene (1836), helium (1868) fluorine (1886), argon (1894), krypton, neon and xenon (1898)  and radon (1899).

Carbon dioxide, hydrogen, nitrous oxide, oxygen, ammonia, chlorine, sulfur dioxide and manufactured fuel gas were already being used during the 19th century, and mainly had uses in food, refrigeration, medicine, and for fuel and gas lighting. For example, carbonated water was being made from 1772 and commercially from 1783, chlorine was first used to bleach textiles in 1785 and nitrous oxide was first used for dentistry anaesthesia in 1844. At this time gases were often generated for immediate use by chemical reactions. A notable example of a generator is Kipps apparatus which was invented in 1844  and could be used to generate gases such as hydrogen, hydrogen sulfide, chlorine, acetylene and carbon dioxide by simple gas evolution reactions. Acetylene was manufactured commercially from 1893 and acetylene generators were used from about 1898 to produce gas for gas cooking and gas lighting, however electricity took over as more practical for lighting and once LPG was produced commercially from 1912, the use of acetylene for cooking declined.

Late Victorian Gasogene for producing carbonated water

Once gases had been discovered and produced in modest quantities, the process of industrialisation spurred on innovation and invention of technology to produce larger quantities of these gases. Notable developments in the industrial production of gases include the electrolysis of water to produce hydrogen (in 1869) and oxygen (from 1888), the Brin process for oxygen production which was invented in the 1884, the chloralkali process to produce chlorine in 1892 and the Haber Process to produce ammonia in 1908.

The development of uses in refrigeration also enabled advances in air conditioning and the liquefaction of gases. Carbon dioxide was first liquefied in 1823. The first Vapor-compression refrigeration cycle using ether was invented by Jacob Perkins in 1834 and a similar cycle using ammonia was invented in 1873 and another with sulfur dioxide in 1876. Liquid oxygen and Liquid nitrogen were both first made in 1883; Liquid hydrogen was first made in 1898 and liquid helium in 1908. LPG was first made in 1910. A patent for LNG was filed in 1914 with the first commercial production in 1917.

Although no one event marks the beginning of the industrial gas industry, many would take it to be the 1880s with the construction of the first high pressure gas cylinders. Initially cylinders were mostly used for carbon dioxide in carbonation or dispensing of beverages. In 1895 refrigeration compression cycles were further developed to enable the liquefaction of air, most notably by Carl von Linde allowing larger quantities of oxygen production and in 1896 the discovery that large quantities of acetylene could be dissolved in acetone and rendered nonexplosive allowed the safe bottling of acetylene.

A particularly important use was the development of welding and metal cutting done with oxygen and acetylene from the early 1900s. As production processes for other gases were developed many more gases came to be sold in cylinders without the need for a gas generator.

Gas production technology

Air separation plants refine air in a separation process and so allow the bulk production of nitrogen and argon in addition to oxygen - these three are often also produced as cryogenic liquid. To achieve the required low distillation temperatures, an Air Separation Unit (ASU) uses a refrigeration cycle that operates by means of the Joule–Thomson effect. In addition to the main air gases, air separation is also the only practical source for production of the rare noble gases neon, krypton and xenon.

Cryogenic technologies also allow the liquefaction of natural gas, hydrogen and helium. In natural-gas processing, cryogenic technologies are used to remove nitrogen from natural gas in a Nitrogen Rejection Unit; a process that can also be used to produce helium from natural gas where natural gas fields contain sufficient helium to make this economic. The larger industrial gas companies have often invested in extensive patent libraries in all fields of their business, but particularly in cryogenics.

Gasification

The other principal production technology in the industry is Reforming. Steam reforming is a chemical process used to convert natural gas and steam into a syngas containing hydrogen and carbon monoxide with carbon dioxide as a byproduct. Partial oxidation and autothermal reforming are similar processes but these also require oxygen from an ASU. Synthesis gas is often a precursor to the chemical synthesis of ammonia or methanol. The carbon dioxide produced is an acid gas and is most commonly removed by amine treating. This separated carbon dioxide can potentially be sequestrated to a carbon capture reservoir or used for Enhanced oil recovery.

Air Separation and hydrogen reforming technologies are the cornerstone of the industrial gases industry and also form part of the technologies required for many fuel gasification ( including IGCC), cogeneration and Fischer-Tropsch gas to liquids schemes. Hydrogen has many production methods and may be almost a carbon neutral alternative fuel if produced by water electrolysis (assuming the electricity is produced in nuclear or other low carbon footprint power plant instead of reforming natural gas which is by far dominant method). One example of displacing the use of hydrocarbons is Orkney; see hydrogen economy for more information on hydrogen's uses. liquid hydrogen is used by NASA in the Space Shuttle as a rocket fuel.

Simpler gas separation technologies, such as membranes or molecular sieves used in pressure swing adsorption or vacuum swing adsorption are also used to produce low purity air gases in nitrogen generators and oxygen plants. Other examples producing smaller amounts of gas are chemical oxygen generators or oxygen concentrators.

In addition to the major gases produced by air separation and syngas reforming, the industry provides many other gases. Some gases are simply byproducts from other industries and others are sometimes bought from other larger chemical producers, refined and repackaged; although a few have their own production processes. Examples are hydrogen chloride produced by burning hydrogen in chlorine, nitrous oxide produced by thermal decomposition of ammonium nitrate when gently heated, electrolysis for the production of fluorine, chlorine and hydrogen, and electrical corona discharge to produce ozone from air or oxygen.

Related services and technology can be supplied such as vacuum, which is often provided in hospital gas systems; purified compressed air; or refrigeration. Another unusual system is the inert gas generator. Some industrial gas companies may also supply related chemicals, particularly liquids such as bromine and ethylene oxide.

Gas distribution

Mode of gas supply

Compressed hydrogen tube trailer

Most materials that are gaseous at ambient temperature and pressure are supplied as compressed gas. A gas compressor is used to compress the gas into storage pressure vessels (such as gas canisters, gas cylinders or tube trailers) through piping systems. Gas cylinders are by far the most common gas storage  and large numbers are produced at a "cylinder fill" facility.

However not all industrial gases are supplied in the gaseous phase. A few gases are vapors that can be liquefied at ambient temperature under pressure alone, so they can also be supplied as a liquid in an appropriate container. This phase change also makes these gases useful as ambient refrigerants and the most significant industrial gases with this property are ammonia (R717), propane (R290), butane (R600), and sulfur dioxide (R764). Chlorine also has this property but is too toxic, corrosive and reactive to ever have been used as a refrigerant. Some other gases exhibit this phase change if the ambient temperature is low enough; this includes ethylene (R1150), carbon dioxide (R744), ethane (R170), nitrous oxide (R744A), and sulfur hexafluoride; however, these can only be liquefied under pressure if kept below their critical temperatures which are 9 °C for C2H4 ; 31 °C for CO2 ; 32 °C for C2H6 ; 36 °C for N2O ; 45 °C for SF6. All of these substances are also provided as a gas (not a vapor) at the 200 bar pressure in a gas cylinder because that pressure is above their critical pressure.

Permanent gases (those with a critical temperature below ambient) can only be supplied as liquid if they are also cooled. All gases can potentially be used as a refrigerant around the temperatures at which they are liquid; for example nitrogen (R728) and methane (R50) are used as refrigerant at cryogenic temperatures.

Exceptionally carbon dioxide can be produced as a cold solid known as dry ice, which sublimes as it warms in ambient conditions, the properties of carbon dioxide are such that it cannot be liquid at a pressure below its triple point of 5.1 bar.

Acetylene is also supplied differently. Since it is so unstable and explosive, this is supplied as a gas dissolved in acetone within a packing mass in a cylinder. Acetylene is also the only other common industrial gas that sublimes at atmospheric pressure.

Gas delivery

Photos gas cabinet inventory

The major industrial gases can be produced in bulk and delivered to customers by pipeline, but can also be packaged and transported.

Most gases are sold in gas cylinders and some sold as liquid in appropriate containers (e.g. Dewars) or as bulk liquid delivered by truck. The industry originally supplied gases in cylinders to avoid the need for local gas generation; but for large customers such as steelworks or oil refineries, a large gas production plant may be built nearby (typically called an "on-site" facility) to avoid using large numbers of cylinders manifolded together. Alternatively, an industrial gas company may supply the plant and equipment to produce the gas rather than the gas itself. An industrial gas company may also offer to act as plant operator under an operations and maintenance contract for a gases facility for a customer, since it usually has the experience of running such facilities for the production or handling of gases for itself.

Some materials are dangerous to use as a gas; for example, fluorine is highly reactive and industrial chemistry requiring fluorine often uses hydrogen fluoride (or hydrofluoric acid) instead. Another approach to overcoming gas reactivity is to generate the gas as and when required, which is done, for example, with ozone.

The delivery options are therefore local gas generation, pipelines, bulk transport (truck, rail, ship), and packaged gases in gas cylinders or other containers.

Bulk liquid gases are often transferred to end user storage tanks. Gas cylinders (and liquid gas containing vessels) are often used by end users for their own small scale distribution systems. Toxic or flammable gas cylinders are often stored by end users in gas cabinets for protection from external fire or from any leak.

What defines an industrial gas

Industrial gas is a group of materials that are specifically manufactured for use in industry and are also gaseous at ambient temperature and pressure. They are chemicals which can be an elemental gas or a chemical compound that is either organic or inorganic, and tend to be low molecular weight molecules. They could also be a mixture of individual gases. They have value as a chemical; whether as a feedstock, in process enhancement, as a useful end product, or for a particular use; as opposed to having value as a "simple" fuel.

The term “industrial gases” is sometimes narrowly defined as just the major gases sold, which are: nitrogen, oxygen, carbon dioxide, argon, hydrogen, acetylene and helium. Many names are given to gases outside of this main list by the different industrial gas companies, but generally the gases fall into the categories "specialty gases", “medical gases”, “fuel gases” or “refrigerant gases”. However gases can also be known by their uses or industries that they serve, hence "welding gases" or "breathing gases", etc.; or by their source, as in "air gases"; or by their mode of supply as in "packaged gases". The major gases might also be termed "bulk gases" or "tonnage gases".

In principle any gas or gas mixture sold by the "industrial gases industry" probably has some industrial use and might be termed an "industrial gas". In practice, "industrial gases" are likely to be a pure compound or a mixture of precise chemical composition, packaged or in small quantities, but with high purity or tailored to a specific use (e.g. oxyacetylene). Lists of the more significant gases are listed in "The Gases" below.

There are cases when a gas is not usually termed an "industrial gas"; principally where the gas is processed for later use of its energy rather than manufactured for use as a chemical substance or preparation.

The oil and gas industry is seen as distinct. So, whilst it is true that natural gas is a "gas" used in "industry" - often as a fuel, sometimes as a feedstock, and in this generic sense is an "industrial gas"; this term is not generally used by industrial enterprises for hydrocarbons produced by the petroleum industry directly from natural resources or in an oil refinery. Materials such as LPG and LNG are complex mixtures often without precise chemical composition that often also changes whilst stored.

The petrochemical industry is also seen as distinct. So petrochemicals (chemicals derived from petroleum) such as ethylene are also generally not described as "industrial gases".

Sometimes the chemical industry is thought of as distinct from industrial gases; so materials such as ammonia and chlorine might be considered "chemicals" (especially if supplied as a liquid) instead of or sometimes as well as "industrial gases".

Small scale gas supply of hand-carried containers is sometimes not considered to be industrial gas as the use is considered personal rather than industrial; and suppliers are not always gas specialists.

These demarcations are based on perceived boundaries of these industries (although in practice there is some overlap), and an exact scientific definition is difficult. To illustrate "overlap" between industries:

Manufactured fuel gas (such as town gas) would historically have been considered an industrial gas. Syngas is often considered to be a petrochemical; although its production is a core industrial gases technology. Similarly, projects harnessing Landfill gas or biogas, Waste-to-energy schemes, as well as Hydrogen Production all exhibit overlapping technologies.

Helium is an industrial gas, even though its source is from natural gas processing.

Any gas is likely to be considered an industrial gas if it is put in a gas cylinder (except perhaps if it is used as a fuel)

Propane would be considered an industrial gas when used as a refrigerant, but not when used as a refrigerant in LNG production, even though this is an overlapping technology.

The known chemical elements which are, or can be obtained from natural resources (without transmutation) and which are gaseous are hydrogen, nitrogen, oxygen, fluorine, chlorine, plus the noble gases; and are collectively referred to by chemists as the "elemental gases". These elements are all primordial apart from the noble gas radon which is a trace radioisotope which occurs naturally since all isotopes are radiogenic nuclides from radioactive decay. These elements are all nonmetals.

(Synthetic elements have no relevance to the industrial gas industry; however for scientific completeness, note that it has been suggested, but not scientifically proven, that metallic elements 112 (Copernicium) and 114 (Flerovium) are gases.)

The elements which are stable two atom homonuclear molecules at standard temperature and pressure (STP), are hydrogen (H2), nitrogen (N2) and oxygen (O2), plus the halogens fluorine (F2) and chlorine (Cl2). The noble gases are all monatomic.

In the industrial gases industry the term "elemental gases" (or sometimes less accurately "molecular gases") is used to distinguish these gases from molecules that are also chemical compounds.

Radon is chemically stable, but it is radioactive and does not have a stable isotope. Its most stable isotope, 222Rn, has a half-life of 3.8 days. Its uses are due to its radioactivity rather than its chemistry and it requires specialist handling outside of industrial gas industry norms. It can however be produced as a by-product of uraniferous ores processing. Radon is a trace naturally occurring radioactive material (NORM) encountered in the air processed in an ASU.

Chlorine is the only elemental gas that is technically a vapor since STP is below its critical temperature; whilst bromine and mercury are liquid at STP, and so their vapor exists in equilibrium with their liquid at STP.
