AT&T Inc., deriving its name from the original American Telephone and Telegraph Company, is a multinational telecommunications holding enterprise based in Whitacre Tower, Dallas, Texas. It stands as the third-largest global telecommunications firm by revenue and ranks third among wireless providers in the United States, following T-Mobile and Verizon. In 2023, AT&T secured the 32nd position on the Fortune 500 list with $122.4 billion in revenue.

The company's lineage dates back to the original AT&T, established in 1885. The present-day corporation resulted from the merger between SBC Corporation (initially Southwestern Bell Corporation, one of the "Baby Bells") and AT&T Corporation. SBC’s origins trace to the American District Telegraph Company, founded in 1878 in St. Louis. Through a series of mergers and growth, it evolved into Southwestern Bell Telephone Company by 1920, operating as a subsidiary under the original AT&T.

Incorporated in 1885 as a subsidiary of Bell Telephone Company—which was founded by Alexander Graham Bell in 1877—AT&T Corporation became the parent entity of the Bell System in 1899. This system maintained an almost complete monopoly over U.S. telephone service for much of the twentieth century, earning the moniker Ma Bell. The company officially adopted the name AT&T Corporation in 1994.

Following the 1982 Modification of Final Judgment, which settled antitrust proceedings, AT&T divested its local operating companies into seven Regional Bell Operating Companies (RBOCs), including Southwestern Bell Corporation (SBC). SBC rebranded to SBC Communications Inc. in 1995 and later acquired fellow Baby Bells Pacific Telesis in 1997 and Ameritech in 1999.

In 2005, SBC purchased its former parent company AT&T Corp., taking on its branding, history, and stock ticker to become AT&T Inc. The combined entity then acquired BellSouth in 2006, gaining full ownership of wireless provider Cingular Wireless, which was subsequently renamed AT&T Mobility.

AT&T entered the media sector by acquiring Time Warner in 2016 for $85 billion, rebranding it as WarnerMedia two years later. However, it divested WarnerMedia in 2022 through a merger with Discovery, Inc., creating Warner Bros. Discovery.

The current incarnation of AT&T encompasses much of the former Bell System infrastructure, including four out of seven Baby Bells and the original long-distance division via subsidiaries such as AT&T Communications and Cricket Wireless. Its strategic focus centers on delivering integrated telecommunications services across fixed-line telephony, mobile communications, broadband internet, and IoT sectors within the United States.

Origins and expansion (1877–1981)

The company began as Bell Telephone Company, founded by Alexander Graham Bell, Thomas Watson, and Gardiner Greene Hubbard following Bell’s telephone patent in 1875. By 1881, it had become known as American Bell Telephone Company. The American Telephone and Telegraph Company (AT&T) was formed in 1885 as a subsidiary tasked with constructing and operating long-distance networks. On December 30, 1899, AT&T acquired its parent company, thus becoming the controlling entity of the Bell System.

AT&T established a nationwide network of local telephone subsidiaries throughout the United States and maintained a monopoly on telephone services under the terms of the 1913 Kingsbury Commitment. This dominance defined the Bell System for much of the twentieth century and led to AT&T being commonly referred to as Ma Bell.

Breakup and reformation (1982–2004)

In 1982, U.S. regulatory authorities ordered the dissolution of the AT&T monopoly, mandating the separation of its local service units into seven distinct Regional Bell Operating Companies, commonly referred to as Baby Bells. Southwestern Bell Corporation, which later became SBC Communications Inc., was one of these newly formed companies.

Following the breakup, AT&T retained its long-distance service operations but encountered increasing rivalry from competitors such as MCI and Sprint. The company engaged in targeted acquisitions, including the purchase of Metromedia's mobile division in 1987 and several cable providers during the early 1990s. Toward the end of that decade, AT&T expanded by acquiring two Baby Bells—Pacific Telesis Group and Ameritech Corporation—while divesting its cable assets.

In 1997, C. Michael Armstrong assumed the role of CEO and appointed John Zeglis as president. By 1998, AT&T was ranked among the top 15 companies on the Fortune 500 list and was added to the Dow Jones Industrial Average in 1999, a position it held until 2015. Zeglis moved on to become chairman and CEO of AT&T Wireless in 1999, stepped down from his AT&T presidency in 2001, and eventually resigned from his leadership at AT&T Wireless in 2004.

Purchase of former parent and acquisitions (2005–2013)

On November 18, 2005, SBC Communications acquired its former parent company, AT&T Corporation, for $16 billion. Post-acquisition, SBC adopted the AT&T name and branding while maintaining SBC’s corporate framework and stock lineage; however, it claimed the heritage of the original AT&T Corporation dating back to 1877. SEC filings prior to 2005 continued under SBC’s name.

In 2011, AT&T attempted to acquire T-Mobile USA for $39 billion but withdrew due to regulatory challenges and government opposition. As part of the agreement's resolution, T-Mobile received $3 billion in cash along with access to $1 billion worth of wireless spectrum owned by AT&T.

Expanding its footprint into Latin America in 2013, AT&T partnered with América Móvil. That year also saw the company announce the sale of its Connecticut wireline operations to Frontier Communications for $2 billion.

A significant strategic acquisition occurred in December 2006 when AT&T purchased BellSouth Corporation for $85.8 billion, consolidating control over Cingular Wireless and substantially growing its customer base. After receiving regulatory clearance, AT&T rebranded all Cingular wireless retail outlets to AT&T in January 2007 to unify its brand presence and capitalize on marketing efficiencies that promised considerable reductions in operating expenses.

Recent developments (2013–present)

Toward the end of 2014, AT&T expanded its North American presence by acquiring Mexican carriers Iusacell and NII Holdings’ wireless business, integrating them into AT&T Mexico. In July 2015, it completed a $48.5 billion acquisition of DirecTV, merging it with U-verse internet and IPTV services under the banner of AT&T Entertainment.

In October 2016, AT&T announced its intention to acquire Time Warner for $108.7 billion to enhance its media assets. Despite facing a Department of Justice lawsuit aimed at blocking the merger on antitrust grounds, a federal judge approved the deal in June 2018; Time Warner was subsequently renamed WarnerMedia. Following this acquisition, AT&T reorganized into four divisions: Communications (covering mobility and video), WarnerMedia (content creation and networks), AT&T Latin America (wireless and video services), and Advertising and Analytics (later rebranded as Xandr).

AT&T introduced cloud-based DVR streaming services culminating in HBO Max's launch in May 2020. The company also planned an over-the-top service resembling cable for wider broadband delivery.

In 2018, AT&T filed for an initial public offering of a minority stake in DirecTV Latin America under Vrio Corp., but canceled these plans due to unfavorable market conditions. By 2019, AT&T held the largest market share within U.S. telecommunications, leading both mobile and fixed-line telephone services.

Activist investor Elliott Management acquired a 1.2% stake in 2019 and advocated for divestitures aimed at increasing shareholder value. In response, AT&T announced substantial cost reductions in 2020 while shifting its pay-TV focus toward promoting AT&T TV as its primary offering; DirecTV continued mainly where broadband access was limited.

John Stankey replaced Randall Stephenson as CEO in July 2020 amidst a heavy debt load approaching $200 billion resulting from previous acquisitions. Plans to sell Warner Bros. Interactive Entertainment were abandoned due to pandemic-driven growth in gaming alongside strong upcoming titles.

Crunchyroll was sold to Sony’s Funimation for $1.175 billion in December 2020 with the transaction closing in August 2021. In February 2021, AT&T spun off DirecTV, U-Verse TV, and DirecTV Stream into a separate company with TPG Capital acquiring a 30% stake; this deal finalized in August 2021.

In May 2021, AT&T announced a plan to spin off WarnerMedia and merge it with Discovery, Inc., completing a $43 billion transaction in April 2022 that formed Warner Bros. Discovery. This restructuring led to HBO Max being removed from AT&T’s unlimited plans.

Electronic Arts purchased Playdemic, a mobile gaming studio previously part of Warner Bros Interactive Entertainment, for $1.4 billion in June 2021. Fox Corporation acquired TMZ from WarnerMedia for roughly $50 million in September that year.

AT&T completed the sale of its advertising platform Xandr to Microsoft by June 2022.

On July 2, 2025, AT&T and TPG Capital concluded the sale of their remaining combined 70% interest in DirecTV, marking the completion of AT&T’s exit from the satellite television business.

2024 Snowflake Data Compromise

In 2024, AT&T was among multiple Snowflake Inc. customers impacted by a significant data breach that revealed phone and text records belonging to nearly all AT&T subscribers during the period from May to October 2022. This event was notable as it represented the inaugural occasion when the Justice Department sought to postpone SEC disclosure due to concerns over national security.

Moreover, AT&T experienced a cyberattack in 2024 attributed to the China-supported Salt Typhoon advanced persistent threat group, which affected U.S. wiretap infrastructures.

Landline Operating Entities

Out of the original eight Bell System companies, five have been integrated into AT&T's corporate framework:

• Ameritech, acquired by SBC in 1999
• AT&T Corp., absorbed by SBC in 2005
• BellSouth, acquired by AT&T in 2006
• Pacific Telesis, acquired by SBC in 1997
• Southwestern Bell, renamed SBC Communications in 1995

Present-Day States

AT&T’s wireline segment provides services across 22 states, including Alabama, Arizona, California, Florida, Georgia, Illinois, Michigan, Texas, and Wisconsin.

Previously Held Companies

Several entities formerly under SBC/AT&T have been divested or merged:

• Woodbury Telephone combined with Southern New England Telephone in 2007.
• Southern New England Telephone was transferred to Frontier Communications in 2014.

Rural Landline Reductions

Over time, multiple Baby Bells divested rural landline assets: Ameritech sold its Wisconsin lines to CenturyTel in 1998; BellSouth transferred certain lines to MebTel during the 2000s; US West sold rural lines to Lynch Communications and Pacific Telecom throughout the 1990s; Verizon sold its New England landlines to FairPoint in 2008 and its West Virginia operations to Frontier in 2010.

In 2014, Frontier Communications purchased AT&T’s landline network in Connecticut for approximately $2 billion, including around 2,500 employees and several operational facilities.

Offices and Geographic Divisions

AT&T’s corporate headquarters are located at Whitacre Tower in downtown Dallas, Texas. On June 27, 2008, the company announced relocating its main office from San Antonio to One AT&T Plaza in Dallas to improve proximity to customers, global operations, technology collaborators, suppliers, and human resources critical for corporate expansion. Prior to that move, the headquarters shifted from St. Louis to San Antonio in 1992 when operating as Southwestern Bell Corporation. The Telecom Operations division serving residential and regional business clients across 22 states remains based in San Antonio.

The headquarters for AT&T Mobility is situated in Atlanta, Georgia, with significant offices also maintained in Redmond, Washington—previously the headquarters of AT&T Wireless Services. Bedminster, New Jersey hosts the Global Business Services division and AT&T Labs, which encompasses the original AT&T Corp. St. Louis continues as the hub for Directory operations and AT&T Advertising Solutions.

For its Asia Pacific activities, AT&T operates a regional headquarters out of Hong Kong and maintains a presence in Mexico. In 2014, AT&T announced its acquisition of Mexican carrier Iusacell, finalized in January 2015. Following this, on April 30, 2015, AT&T completed the purchase of wireless operator Nextel Mexico from NII Holdings, further solidifying its position within the Mexican telecommunications market.

As of March 2024, the board of directors at AT&T comprises the following members:

The executive leadership team as of March 2024 consists of:

• John Stankey – Chief Executive Officer
• Thaddeus Arroyo – Chief Strategy and Development Officer
• Pascal Desroches – Senior Executive Vice President and Chief Financial Officer
• Ed Gillespie – Senior Executive Vice President for External and Legislative Affairs

Political involvement

Between 1989 and 2019, AT&T ranked as the fourteenth-largest contributor to federal political campaigns in the United States, donating over , with approximately 42% directed to Republican candidates and 58% to Democrats. In 2005, the company was among the leading supporters of President George W. Bush’s second inauguration. Bill Leahy serves as AT&T’s representative on the Private Enterprise Board of the American Legislative Exchange Council (ALEC), an organization responsible for developing model legislation at the state level.

From 1998 through 2019, AT&T invested in lobbying efforts totaling , primarily advocating for broadband internet access rights and backing federal legislation such as the Federal Communications Commission Process Reform Act of 2013, which seeks to enhance transparency within the FCC. Tim McKone, Executive Vice President of Federal Relations, highlighted the bill’s importance in updating regulatory frameworks.

In 2017, AT&T made monthly payments of $600,000 to Essential Consultants, a firm owned by Michael Cohen, who was President Donald Trump’s attorney. These payments were related to counsel on its $85 billion acquisition of Time Warner and advice regarding tax reform and net neutrality issues. These transactions commenced shortly after President Trump took office. AT&T acknowledged these disclosures and cooperated with Special Counsel Robert Mueller’s investigation.

In early 2019, the Democratic-controlled House Judiciary Committee requested documents from the White House concerning the AT&T-Time Warner merger.

While publicly advocating for LGBTQ rights, AT&T has also contributed financially to entities that back anti-transgender legislation in several predominantly Republican states such as Arkansas, Tennessee, North Carolina, Texas, and Florida.

Carbon footprint

For the year ending December 31, 2020, AT&T reported combined direct and indirect CO2e emissions totaling 5,788 kilotonnes, marking an annual decrease of 11.3%. The company has set a goal to reduce its emissions by 63% by the year 2030 compared to levels recorded in 2015, in line with the Paris Agreement objective to limit global temperature rise to 1.5 °C above pre-industrial levels. This commitment forms a key component of AT&T's sustainability initiatives and bolsters its corporate responsibility standing.

Dec. 2015	Dec. 2017	Dec. 2018	Dec. 2019	Dec. 2020
8,829	7,801	7,749	6,525	5,788

Hemisphere database

Since 1987, the company has maintained a comprehensive database containing call detail records for all telephone communications routed through its network. To facilitate law enforcement access, AT&T personnel are stationed at High Intensity Drug Trafficking Area offices located in Los Angeles, Atlanta, and Houston, processing data requests submitted via administrative subpoenas without requiring court authorization.

Censorship

In September of 2007, AT&T amended its legal terms to permit immediate termination of services if a customer's behavior was deemed harmful to the company's reputation or interests; however, after public criticism surfaced, the policy was revised by October of the same year to explicitly affirm subscribers' rights to free expression online.

Privacy controversy

The Electronic Frontier Foundation initiated Hepting v. AT&T in 2006, accusing the company of facilitating warrantless surveillance by the NSA on customer communications, potentially infringing upon constitutional protections and the Foreign Intelligence Surveillance Act provisions in the United States legal framework; affidavits supporting these claims were provided by former technician Mark Klein, while the Department of Justice invoked State Secrets Privilege during proceedings leading to dismissal in 2009 following retroactive amendments to FISA.

Additional reports revealed that AT&T cooperated with other telecommunications providers in supplying extensive call metadata to the NSA for inclusion in a large-scale surveillance database; subsequently, in June of that year, AT&T updated its privacy policy asserting ownership over customer data to safeguard corporate interests and comply with legal demands.

In August of the following year, National Intelligence Director Mike McConnell publicly acknowledged AT&T's involvement in warrantless wiretapping operations; Mark Klein disclosed that internet traffic was duplicated into a secure facility accessible solely by NSA-cleared personnel.

AT&T retains metadata concerning senders and recipients of text messages for a period ranging from five to seven years but does not store the actual message content itself; due to these practices, the Electronic Frontier Foundation has assigned the company a one-star rating regarding privacy protections.

Copyright enforcement

In early 2008, it was reported that the company intended to implement filtering of all Internet traffic on its network to detect intellectual property infringements. Industry analysts cautioned that this approach might provoke a significant loss of subscribers, although traffic from non-subscribers could still traverse the network unfiltered. These plans intensified debates advocating for government-enforced network neutrality protections.

Currently, AT&T’s method of enforcing copyright relies on content owners alerting the company to suspected illegal sharing by identifying IP addresses involved in peer-to-peer networks, rather than actively filtering data streams. The company has discontinued broadband service for certain customers accused of repeated copyright violations after educational warnings failed to curb such activities.

Discrimination against local public-access television channels

In 2009, community media organizations accused AT&T of unfairly limiting the reach of local public, educational, and government access (PEG) cable channels. Barbara Popovic, executive director of Chicago Access Network Television (CAN-TV), reported that AT&T’s U-verse platform placed PEG channels within a separate menu, stripping away standard functionalities such as channel numbering, program guides, and DVR capabilities. The Ratepayer Advocates division of the California Public Utilities Commission observed that AT&T grouped community stations into a generic channel requiring complicated navigation. Sue Buske, president of the Buske Group and former leader of the National Federation of Local Cable Programmers, characterized this practice as a nationwide assault on public access media.

Information security

In June 2010, the hacker collective Goatse Security revealed a security flaw in AT&T’s infrastructure that permitted unauthorized retrieval of email addresses belonging to Apple iPad 3G users without needing passwords. Utilizing an automated script, they harvested thousands of email addresses and shared approximately 114,000 with Gawker Media to expose weaknesses in the web application design. Goatse Security notified AT&T through an intermediary prior to public disclosure.

In April 2015, the Federal Communications Commission (FCC) imposed a $25 million penalty on AT&T due to data security lapses resulting in theft of nearly 280,000 customer records from call centers located in Mexico, Colombia, and the Philippines—marking the FCC’s largest fine for privacy violations at that time.

By March 2024, AT&T acknowledged a data breach dating back to 2021 that compromised contact details for over 7.6 million active users and 65 million former customers. The exposed information included sensitive identifiers such as social security numbers and account specifics. This incident has triggered multiple class-action lawsuits.

In July 2024, AT&T reported another significant breach—the largest recorded—affecting close to 110 million customers with stolen phone records. The company is currently engaged in notifying those impacted following this major cybersecurity event.

Accusations of enabling fraud

In March 2012, the U.S. federal government filed a lawsuit against AT&T alleging violations of the False Claims Act by facilitating and billing for IP Relay calls made by unauthorized international users exploiting the service fraudulently. The suit asserted that AT&T knowingly employed a registration system lacking proper verification of U.S.-based users’ locations, which allowed up to 95% of call traffic to originate from fraudulent foreign callers. The company was charged with improper billing to the TRS Fund and receiving millions in federal reimbursements. In 2013, AT&T reached a settlement with the FCC by paying $21.75 million.

Aaron Slator dispute

On April 28, 2015, AT&T dismissed Aaron Slator, then-President of Content and Advertising Sales, following the circulation of racially offensive text messages. Subsequently, an African-American staff member initiated a $100 million defamation lawsuit against Slator. Demonstrations erupted at AT&T's Dallas headquarters, regional offices, and the residence of CEO Randall Stephenson, demanding partnerships with media outlets that are entirely black-owned.

In January 2017, Slator filed a lawsuit against AT&T alleging defamation and wrongful termination, contending he was unfairly scapegoated to shield the corporation’s $48.5 billion DirecTV acquisition. He asserted that company leadership had been aware of the messages since 2013 and had assured him that no dismissal would occur. AT&T upheld its termination decision, reaffirming its dedication to diversity and inclusion initiatives.

Government agency overbilling

In 2020, AT&T resolved a lawsuit involving 30 governmental bodies by agreeing to pay $48 million under the California False Claims Act. The case centered on allegations that AT&T breached contractual obligations to deliver services at "the lowest cost available." The company denied any misconduct.

One America News Network involvement

A Reuters investigation in 2021 exposed AT&T’s substantial role in establishing, financing, and supporting One America News Network (OAN), a far-right television channel known for disseminating conspiracy narratives. Testimony under oath revealed that approximately 90% of OAN's income was derived from AT&T. Robert Herring Sr., OAN’s founder, indicated that AT&T sought to launch a conservative alternative to Fox News. Legal documents disclosed that OAN consented to portray AT&T favorably during its programming. AT&T refuted these claims. The company’s association with OAN attracted criticism from NAACP president Derrick Johnson and comedian John Oliver.

Unauthorized disclosure of information to Wall Street

In March 2021, the U.S. Securities and Exchange Commission (SEC) filed suit against AT&T and three executives for breaching the Fair Disclosure Rule by selectively providing "material nonpublic information" to Wall Street analysts. These disclosures reportedly began in early 2016 and were intended to influence AT&T’s revenue projections.

By December 2022, AT&T consented to a $6.25 million settlement without admitting wrongdoing. Each implicated executive was penalized with a $25,000 fine.

Illegal lobbying practices

In October 2022, AT&T agreed to pay a $23 million penalty to settle a federal criminal investigation related to illicit attempts to sway former Illinois House Speaker Michael J. Madigan. Under a deferred prosecution agreement with the United States Department of Justice, AT&T acknowledged orchestrating payments to an associate of Madigan in exchange for his support in passing legislation during 2017 that eliminated AT&T’s expensive "Carrier of Last Resort" landline service requirement in Illinois.

Madigan also played a role in blocking a 2018 amendment concerning fees for small cell tower attachments that would have negatively impacted AT&T’s business interests. Paul La Schiazza, former president of AT&T Illinois and scheduled for trial in September 2024 regarding the bribery case, referred internally to this arrangement with Madigan as "the friends and family plan."

2024 outage

On February 22, 2024, a major disruption affected AT&T's cellular network throughout the United States, rendering service unavailable to "millions" of users. Numerous customers reported an inability to contact emergency responders, even when utilizing SOS functions. While the FBI and Department of Homeland Security investigated the possibility of a cyberattack, AT&T attributed the outage to an improperly timed server update. In response, the company provided affected subscribers with credits as compensation. Subsequently, in March, the Federal Communications Commission (FCC) initiated an official inquiry into the event.

2024 Data Breach Penalty

On September 18, 2024, the Federal Trade Commission (FTC) imposed a $13 million penalty on AT&T following a substantial data breach that compromised personal details of millions of customers. The FTC determined that AT&T's cybersecurity protocols were insufficient and criticized the company for delaying notification to those impacted. The settlement mandates enhancements to AT&T’s data security practices and requires offering identity theft protection services to affected individuals.
