AT&T

Origin and growth (1877–1981)

AT&T was founded as Bell Telephone Company by Alexander Graham Bell, Thomas Watson and Gardiner Greene Hubbard after Bell's patenting of the telephone in 1875.^[22] By 1881, Bell Telephone Company had become the American Bell Telephone Company.^[23] One of its subsidiaries was the American Telephone and Telegraph Company (AT&T), established in 1885.^[24] On December 30, 1899, AT&T acquired the assets of its parent American Bell Telephone, becoming the new parent company.^[25] AT&T established a network of local telephone subsidiaries in the United States. AT&T and its subsidiaries held a phone service monopoly, authorized in 1913 by government authorities with the Kingsbury Commitment, throughout most of the twentieth century.^[26] This monopoly was known as the Bell System,^[27] and during this period, AT&T was also known by the nickname Ma Bell.^[28]

Breakup and reformation (1982–2004)

In 1982, U.S. regulators broke up the AT&T monopoly, requiring AT&T to divest its local subsidiaries, which it did by grouping them into seven individual companies.^[29] These new companies were known as Regional Bell Operating Companies, or more informally, Baby Bells.^[30] AT&T continued to operate long-distance services but faced increasing competition from competitors such as MCI and Sprint.^[31]

Southwestern Bell Corporation (SBC) was one of the companies created by the breakup of AT&T Corp.^[32] The company soon started a series of acquisitions, including the 1987 acquisition of Metromedia mobile business and the acquisition of several cable companies in the early 1990s.^{[citation needed]} In the latter half of the 1990s, the company acquired several other telecommunications companies, including two Baby Bells (Pacific Telesis Group and Ameritech Corporation),^[33] while selling its cable business. During this time, the company changed its name to SBC Communications Inc.^[34] In early 1997 C. Michael Armstrong was named CEO, and Armstrong appointed John Zeglis as president later in that same year. By 1998, the company was in the top 15 of the Fortune 500, and by 1999, when Zeglis assumed the positions of chairman and CEO of AT&T Wireless, AT&T was part of the Dow Jones Industrial Average (lasting through 2015).^[35][36] Zeglis ended his service as president of AT&T in 2001 and resigned from his positions in AT&T Wireless in 2004.

Purchase of former parent and acquisitions (2005–2013)

On November 18, 2005, SBC Communications purchased its former parent, AT&T Corporation for $16 billion.^[37] After this purchase, SBC adopted the better-known AT&T name and brand, with the original AT&T Corporation still existing as the long-distance landline subsidiary of the merged company.^[38] The current AT&T Inc. claims the original AT&T Corporation's history (dating to 1877) as its own,^[39] but retains SBC's pre-2005 corporate structure and stock price history. As well, all SEC filings before 2005 are under SBC, not AT&T.

AT&T made an attempt in 2011 to purchase T-Mobile for a $39 billion stock and cash offer.^[40] The bid was withdrawn after the takeover company was faced with significant regulatory and legal hurdles, along with heavy resistance from the U.S. government. As per the original acquisition agreement, T-Mobile received $3 billion in cash as well as access to $1 billion worth of AT&T-held wireless spectrum.^[41][42]

In September 2013, AT&T announced it would expand into Latin America through a collaboration with América Móvil.^[43] In December 2013, AT&T announced plans to sell its Connecticut wireline operations to Stamford-based Frontier Communications.^[44]

AT&T acquired BellSouth Corporation on December 29, 2006, following FCC approval.^[45] The transaction consolidated ownership and management of Cingular Wireless.^[46] AT&T rebranded its wireless retail stores from Cingular to AT&T in January 2007.^[47]

Recent developments (2013–present)

In late 2014, AT&T purchased Mexican cellular carrier Iusacell,^[48] and two months later, it purchased the Mexican wireless business of NII Holdings.^[49] AT&T merged the two companies to create AT&T Mexico.^[50]

In July 2015, AT&T purchased DirecTV for $48.5 billion.^[51][52][53] AT&T then announced plans to converge its existing U-verse home internet and IPTV brands with DirecTV, to create AT&T Entertainment.^[54][55][56]

On October 22, 2016, AT&T announced a deal to buy Time Warner for $108.7 billion in an effort to increase its media holdings.^{[57][58][59][60][61][62]} On November 20, 2017, Assistant Attorney General Makan Delrahim filed a lawsuit for the United States Department of Justice Antitrust Division to block the merger with Time Warner, saying it "will harm competition, result in higher bills for consumers and less innovation."^[63][64] On June 12, 2018, U.S. District Court Judge Richard J. Leon ruled that the merger could go forward.^[65] The merger closed two days afterwards, with Time Warner becoming a wholly owned subsidiary of AT&T. A day later, the company was renamed WarnerMedia.^[66][67]

Three months after completing the acquisition, AT&T reorganized into four main units: Communications, including consumer and business wireline telephony, AT&T Mobility, and consumer entertainment video services; WarnerMedia, including Turner cable television networks, Warner Bros. film and television production, and HBO; AT&T Latin America, consisting of wireless service in Mexico and video in Latin America and the Caribbean under the Vrio brand; and Advertising and Analytics, since renamed Xandr.^[68][69]

On July 13, 2017, it was reported that AT&T would introduce a cloud-based DVR streaming service. It hoped to create a unified platform across DirecTV and its DirecTV Now streaming service, with U-verse to be added shortly afterward.^[70][71][72] The service, named HBO Max, launched in May 2020.^[73]

On September 12, 2017, it was reported that AT&T planned to launch a new cable TV-like service for delivery over-the-top over its own or a competitor's broadband network sometime the following year.^[74]

On March 7, 2018, the company prepared to sell a minority stake of DirecTV Latin America through an IPO, creating a new holding company for those assets named Vrio Corp.^[75][76] On April 18, just a day before the public debut of Vrio, AT&T canceled the IPO due to market conditions.^[77][78]

As of 2019,^[update] AT&T is the world's largest telecommunications company.^[79] AT&T is also the largest provider of mobile telephone^[80][81] services and the largest provider of fixed telephone (landline) services in the United States.^[82]

In September 2019, activist investor Elliott Management revealed that it had purchased $3.2 billion of AT&T stock (a 1.2% equity interest), and had pushed for the company to divest assets to improve its share value.^[83]

On March 4, 2020, AT&T announced its intent to perform major cost-cutting moves, including cuts to capital investment, and plans to promote AT&T TV (which officially launched nationally on March 2) as its primary pay television service offering. AT&T stated it would still primarily promote DirecTV "where cable broadband is not prevalent", and as a specialty option.^[84]

On April 24, 2020, AT&T announced that effective July 1, 2020, company COO John Stankey would replace Randall L. Stephenson as CEO of AT&T.^[85] It was also acknowledged that AT&T's acquisitions of DirecTV and Time Warner had by this point resulted in a massive debt burden of $200 billion for the company.^[85]

As a result of planned cost cutting programs, the sale of Warner Bros. Interactive Entertainment was proposed, but ultimately abandoned due to COVID-19 pandemic-related growth in the video gaming industry, as well as a positive reception to upcoming DC Comics, Lego Star Wars, and Harry Potter titles from fans and critics.^[86]

Crunchyroll was sold to Sony's Funimation for US$1.175 billion in December 2020, with the acquisition closing in August 2021.^[87][88]

On February 25, 2021, AT&T announced that it would spin-off DirecTV, U-Verse TV, and DirecTV Stream into a separate entity, selling a 30% stake to TPG Capital (owners of Astound Broadband cable), while retaining a 70% stake in the new standalone company. The deal was closed on August 2, 2021.^[89][90]

On May 17, 2021, AT&T announced plans to relinquish its equity interest in WarnerMedia, and have it merge with Discovery, Inc. in a US$43 billion deal to establish a new media company.^[91]

Electronic Arts, which was a bidder in the proposed sale of Warner Bros Interactive Entertainment, purchased the mobile gaming studio Playdemic from WBIE for US$1.4 billion in June 2021.^[92]

In September 2021, Fox Corporation acquired TMZ from WarnerMedia in a deal worth about $50 million with TMZ being operated under the Fox Entertainment division.^[93]

On December 21, 2021, AT&T announced that they had agreed to sell Xandr (and AppNexus) to Microsoft for an undisclosed price.^[94] The deal was completed in June 2022.^[95]

On April 8, 2022, the spinoff of WarnerMedia and its subsequent merger with Discovery, Inc. to form Warner Bros. Discovery was completed.^[96] As a result of this merger, HBO Max and other video services were dropped from AT&T's unlimited plan offering.^[97]

AT&T was one of several clients of Snowflake Inc. that had data stolen in a 2024 breach.^[98] Phone and text logs from May 1, 2022 to October 31, 2022 of "nearly all" AT&T customers were exposed as part of the breach.^[99] AT&T was also reported to have been affected by a 2024 attack from the Salt Typhoon advanced persistent threat linked to the Chinese government.^[100]

Decline of rural landlines

Of the Baby Bells, Ameritech sold some of its Wisconsin landlines to CenturyTel, in 1998; BellSouth sold some of its lines to MebTel, during the 2000s; US West sold many historically Bell landlines to Lynch Communications and Pacific Telecom, in the 1990s; Verizon sold many of its New England lines to FairPoint in 2008, and its West Virginia operations to Frontier Communications in 2010.

On October 25, 2014, Frontier Communications took over control of the AT&T landline network in Connecticut after being approved by state utility regulators. The deal was worth about $2 billion, and included Frontier inheriting about 2,500 of AT&T's employees and many of AT&T's buildings.^[105]

Facilities and regions

This section needs expansion. You can help by adding to it. (November 2016)

The company is headquartered at Whitacre Tower in downtown Dallas, Texas.^[5] On June 27, 2008, AT&T announced that it would move its corporate headquarters from downtown San Antonio to One AT&T Plaza in downtown Dallas.^[5][106] The company said that it moved to gain better access to its customers and operations throughout the world, and to the key technology partners, suppliers, innovation and human resources needed as it continues to grow, domestically and internationally.^[107] AT&T Inc. previously relocated its corporate headquarters to San Antonio from St. Louis, Missouri, in 1992, when it was then named Southwestern Bell Corporation. The company's Telecom Operations group, which serves residential and regional business customers in 22 U.S. states, remains in San Antonio.^[108][109] Atlanta, Georgia, continues to be the headquarters for AT&T Mobility, with significant offices in Redmond, Washington, the former home of AT&T Wireless. Bedminster, New Jersey, is the headquarters for the company's Global Business Services group and AT&T Labs and is where the original AT&T Corp. remains located. St. Louis continues as home to the company's Directory operations, AT&T Advertising Solutions.^[110]

AT&T also offers services in many locations throughout the Asia Pacific; its regional headquarters is located in Hong Kong.^[111] The company is also active in Mexico, and on November 7, 2014, it was announced that Mexican carrier Iusacell would be acquired by AT&T.^[48] The acquisition was approved in January 2015.^[112][113] On April 30, 2015, AT&T acquired wireless operations Nextel Mexico from NII Holdings (now AT&T Mexico).^[114]

Hemisphere database

The company maintains a database of call detail records of all telephone calls that have passed through its network since 1987. AT&T employees work at High Intensity Drug Trafficking Area offices (operated by the Office of National Drug Control Policy) in Los Angeles, Atlanta, and Houston so data can be quickly turned over to law enforcement agencies. Records are requested via an administrative subpoena, without the involvement of a court or grand jury.

Censorship

In September 2007, AT&T changed its legal policy to state that "AT&T may immediately terminate or suspend all or a portion of your Service, any Member ID, electronic mail address, IP address, Universal Resource Locator or domain name used by you, without notice for conduct that AT&T believes ... (c) tends to damage the name or reputation of AT&T, or its parents, affiliates and subsidiaries."^[161] By October 10, 2007, AT&T had altered the terms and conditions for its Internet service to explicitly support freedom of expression by its subscribers, after an outcry claiming the company had given itself the right to censor its subscribers' transmissions.^[162]

Privacy controversy

In 2006, the Electronic Frontier Foundation lodged the class action lawsuit Hepting v. AT&T, which alleged that AT&T had allowed agents of the National Security Agency (NSA) to monitor phone and Internet communications of AT&T customers without warrants. If true, this would violate the Foreign Intelligence Surveillance Act of 1978 and the First and Fourth Amendments of the U.S. Constitution. AT&T has yet to confirm or deny that monitoring by the NSA is occurring. In April 2006, retired former AT&T technician Mark Klein lodged an affidavit supporting this allegation.^[164][165] The US Department of Justice stated it would intervene in this lawsuit by means of State Secrets Privilege.^[166]

In July 2006, the United States District Court for the Northern District of California – in which the suit was filed – rejected a federal government motion to dismiss the case. The motion to dismiss, which invoked the State Secrets Privilege, had argued that any court review of the alleged partnership between the federal government and AT&T would harm national security. The case was immediately appealed to the Ninth Circuit. It was dismissed on June 3, 2009, citing retroactive legislation in the Foreign Intelligence Surveillance Act.^[167][168]

In May 2006, USA Today reported that all international and domestic calling records had been handed over to the National Security Agency by AT&T, Verizon, SBC, and BellSouth for the purpose of creating a massive calling database.^[169] The portions of the new AT&T that had been part of SBC Communications before November 18, 2005, were not mentioned.

On June 21, 2006, the San Francisco Chronicle reported that AT&T had rewritten rules on its privacy policy. The policy, which took effect June 23, 2006, says that "AT&T – not customers – owns customers' confidential info and can use it 'to protect its legitimate business interests, safeguard others, or respond to legal process.'"^[170]

On August 22, 2007, National Intelligence Director Mike McConnell confirmed that AT&T was one of the telecommunications companies that assisted with the government's warrantless wire-tapping program on calls between foreign and domestic sources.^[171]

On November 8, 2007, Mark Klein, a former AT&T technician, told Keith Olbermann of MSNBC that all Internet traffic passing over AT&T lines was copied into a locked room at the company's San Francisco office – to which only employees with National Security Agency clearance had access.^[172]

AT&T keeps for five to seven years a record of who text messages whom and the date and time, but not the content of the messages.^[173]

AT&T has a one star privacy rating from the Electronic Frontier Foundation.^[174]

Copyright enforcement

In January 2008, reports emerged that the company planned to begin filtering all Internet traffic which passed through its network for intellectual property violations.^[175] Media commentators speculated that if this plan was implemented, it would have led to a mass exodus of subscribers from AT&T,^[176] although Internet traffic of non-subscribers may have gone through the company's network anyway.^[175] Internet freedom proponents used these developments as justification for government-mandated network neutrality.

Under AT&T's current copyright enforcement program, content owners may notify AT&T when they allege unlawful sharing of material. The program is based on IP addresses visible to content owners in peer-to-peer networks, not on filtering. AT&T has terminated the broadband service of some customers accused of copyright infringement.^[177]

Discrimination against local public-access television channels

In 2009 AT&T was accused by community media groups of discriminating against local public, educational, and government access (PEG) cable TV channels, by "impictions that will severely restrict the audience".^[178]

According to Barbara Popovic, executive director of the Chicago public-access service CAN-TV, the new AT&T U-verse system forced all Public-access television into a special menu system, denying normal functionality such as channel numbers, access to the standard program guide, and DVR recording.^[178] The Ratepayer Advocates division of the California Public Utilities Commission reported: "Instead of putting the stations on individual channels, AT&T has bundled community stations into a generic channel that can only be navigated through a complex and lengthy process."^[178]

Sue Buske (president of telecommunications consulting firm the Buske Group and a former head of the National Federation of Local Cable Programmers/Alliance for Community Media) argue that this is "an overall attack [...] on public access across the [United States], the place in the dial around cities and communities where people can make their own media in their own communities".^[178]

Information security

In June 2010, a hacker group known as Goatse Security discovered a vulnerability within AT&T that could allow anyone to uncover email addresses belonging to customers of AT&T 3G service for the Apple iPad.^[179] These email addresses could be accessed without a protective password.^[180] Using a script, Goatse Security collected thousands of email addresses from AT&T.^[179] Goatse Security informed AT&T about the security flaw through a third party.^[181] Goatse Security then disclosed around 114,000 of these emails to Gawker Media, which published an article about the security flaw and disclosure in Valleywag.^[179][181] Praetorian Security Group criticized the web application that Goatse Security exploited as "poorly designed".^[179]

In April 2015, AT&T was fined $25 million over data security breaches, marking the largest ever fine issued by the Federal Communications Commission (FCC) for breaking data privacy laws. The investigation revealed the theft of details of approximately 280,000 people from call centers in Mexico, Colombia and the Philippines.^[182][183]

In March 2024, AT&T confirmed the 2021 leak of contact information for over 7.6 million current users, as well as 65 million former ones. The leaked records may contain "full name, email address, mailing address, phone number, social security number, date of birth, AT&T account number and passcode".^[184] Multiple class-action lawsuits have been filed as a result of this.^[185][186]

In July 2024, the company stated it experienced a new breach, the largest to date. The company is expected to notify around 110 million customers who were affected.^[187]

Accusations of enabling fraud

In March 2012, the United States federal government announced a lawsuit against AT&T. The specific accusations state that AT&T "violated the False Claims Act by facilitating and seeking federal payment for IP Relay calls by international callers who were ineligible for the service and sought to use it for fraudulent purposes. The complaint alleges that, out of fears that fraudulent call volume would drop after the registration deadline, AT&T knowingly adopted a non-compliant registration system that did not verify whether the user was located within the United States. The complaint further contends that AT&T continued to employ this system even with the knowledge that it facilitated the use of IP Relay by fraudulent foreign callers, which accounted for up to 95 percent of AT&T's call volume. The government's complaint alleges that AT&T improperly billed the TRS Fund for reimbursement of these calls and received millions of dollars in federal payments as a result."^[188] In 2013, AT&T entered into a consent decree with the FCC and paid a total of $21.75 million.^[189]

Aaron Slator controversy

On April 28, 2015, AT&T announced that it had fired Aaron Slator, President of Content and Advertising Sales, for sending text messages critics described as racist.^[190] African-American employee Knoyme King filed a $100 million defamation lawsuit against Slator.^[191] The day before that, protesters arrived at AT&T's headquarters in Dallas and its satellite offices in Los Angeles as well as at the home of CEO Randall Stephenson to protest alleged systemic racial policies. According to accounts, the protesters demanded that AT&T begin working with 100% black-owned media companies.^[192]

On January 24, 2017, Slator sued AT&T in the Los Angeles Superior Court, accusing the company of defamation and wrongful termination. Slator had been involved in organizing AT&T's planned $48.5 billion acquisition of DirecTV since 2014, and he claimed that when news headlines speculated that his text messages could prevent the acquisition from going through, he was fired as a "scapegoat" by company executives. He also claimed that the executives had known about the text messages since at least late 2013, and had promised him at the time that he would not be fired for them.^[193][194] The company stood by its decision to terminate Slator.^[195]

Overcharging government agencies

In 2020 AT&T paid out $48 million to settle a lawsuit with 30 government entities. The suit (under the California False Claims Act) related to contractual undertakings to provide services at "the lowest cost available". AT&T denied any wrongdoing in the matter.^[196]

One America News Network

An investigative report by Reuters in 2021 revealed that AT&T played a key role in creating, funding and sustaining One America News Network (OAN), a far-right TV network known for promoting conspiracy theories.^[197] According to 2020 sworn testimony by an OAN accountant, 90% of OAN's revenue came from AT&T. According to OAN founder Robert Herring Sr., AT&T wanted to create a conservative network to compete with Fox News. Court documents showed OAN promised to "cast a positive light" on AT&T during newscasts. AT&T denied the allegations.^[198][199] Comedian John Oliver criticized AT&T in his weekly show for funding OAN.^[200]

Leaking data to Wall Street

In March 2021 the U.S. Securities and Exchange Commission (SEC) filed suit against AT&T and three of its executives for violating the Fair Disclosure Rule against making selective disclosures of "material nonpublic information" to analysts and others. The SEC alleged that beginning in early 2016 these executives leaked key information to Wall Street analysts in order to manipulate revenue forecasts for the company.^[201]

In December 2022, without acknowledging any guilt, AT&T agreed to pay $6.25 million in fines to settle the lawsuit. The individual executives were also on the hook for $25,000 each.^[201][202]

Bribery to influence legislation

In October 2022, AT&T agreed to pay a $23 million fine to resolve a federal criminal investigation into the company's efforts to unlawfully influence former Illinois Speaker of the House Michael J. Madigan.^[203] Under a deferred prosecution with the US Department of Justice, AT&T admitted that it arranged for payments to an ally of Madigan in order to influence Madigan's vote in 2017 on legislation that would eliminate AT&T's so-called "Carrier of Last Resort" obligation to provide landline telephone service to all Illinois residents, which was expected to save the company millions of dollars.^[203] Madigan also helped to defeat an amendment to a bill that became law in 2018 regarding fees for small cell tower attachments that would have been harmful to AT&T's interests.^[204] Former AT&T Illinois President Paul La Schiazza, who is set to go on trial in September 2024 for the alleged bribery scheme, described AT&T's quid pro quo relationship with Madigan in an email to an AT&T employee as "the friends and family plan."^[204]

2024 outage

On February 22, 2024, cellular service was disrupted across the United States with "millions" unable to connect to the cellular network.^[205] Municipalities reported that AT&T customers were unable to place calls to emergency services, even when using their phone's SOS capability.^[206] The blackout prompted the FBI and Department of Homeland Security to launch investigations into the possibility of a cyber attack being the cause of the blackout.^[207] AT&T later claimed that the cause was instead a poorly timed server update.^[208] Users were later compensated credit as a result of the outage.^[209] In March, the FCC opened an investigation into the outage.^[205]

2024 Data Breach Fine

On September 18, 2024, AT&T was fined $13 million by the Federal Trade Commission (FTC) following a major data breach that exposed millions of customers' personal information. The FTC found that AT&T failed to implement adequate cybersecurity measures and did not promptly notify affected individuals. As part of the settlement, AT&T is required to enhance its data protection practices and provide identity theft protection to those impacted.^[210]
