AT&T

AT&T Inc. is an American multinational conglomerate holding company headquartered at Whitacre Tower in Downtown Dallas, Texas. It is the world's largest telecommunications company, the largest provider of mobile telephone services, and the largest provider of fixed telephone services in the United States through AT&T Communications. Since June 14, 2016, it is also the parent company of mass media conglomerate WarnerMedia, making it the world's largest media and entertainment company in terms of revenue. , AT&T is ranked #9 on the Fortune 500 rankings of the largest United States corporations by total revenue.

AT&T began its history as Southwestern Bell Telephone Company, a subsidiary of the Bell Telephone Company, founded by Alexander Graham Bell in 1877. The Bell Telephone Company became the American Telephone and Telegraph Company in 1885 and was later rebranded as AT&T Corporation. The 1982 United States v. AT&T antitrust lawsuit resulted in the divestiture of AT&T Corporation's ("Ma Bell") subsidiaries or Regional Bell Operating Companies (RBOCs), commonly referred to as "Baby Bells", resulting in several independent companies, including Southwestern Bell Corporation; the latter changed its name to SBC Communications Inc. in 1995. In 2005, SBC purchased its former parent AT&T Corporation and took on its branding, with the merged entity naming itself AT&T Inc. and using its iconic logo and stock-trading symbol. In 2006, AT&T Inc. acquired BellSouth, the last independent Baby Bell company, making their formerly joint venture Cingular Wireless (which had acquired AT&T Wireless in 2004) wholly owned and rebranding it as AT&T Mobility.

The current AT&T reconstitutes much of the former Bell System, and includes ten of the original 22 Bell Operating Companies along with the original long distance division.

Origin and growth (1885–1981)
AT&T traces its origins to the Bell Telephone Company, founded by Alexander Graham Bell, Gardiner Greene Hubbard, and Thomas Sanders after Bell's patenting of the telephone. which acquired the Bell Company on December 31, 1899, for legal reasons, leaving AT&T as the main company. AT&T established a network of subsidiaries in the United States and Canada that held a phone service monopoly, authorized by government authorities with the Kingsbury Commitment, throughout most of the twentieth century. This monopoly was known as the Bell System, and during this period, AT&T was also known by the nickname Ma Bell. For periods of time, the former AT&T was the world's largest phone company.

Breakup and reformation (1982–2004)
In 1982, U.S. regulators broke up the AT&T monopoly, requiring AT&T to divest its regional subsidiaries and turning them each into individual companies. These new companies were known as Regional Bell Operating Companies, or more informally, Baby Bells. AT&T continued to operate long distance services, but as a result of this breakup, faced competition from new competitors such as MCI and Sprint.

Southwestern Bell was one of the companies created by the breakup of AT&T Corp. The architect of divestiture for Southwestern Bell was Robert G. Pope. The company soon started a series of acquisitions. This includes the 1987 acquisition of Metromedia mobile business and the acquisition of several cable companies in the early 1990s. In the latter half of the 1990s, the company acquired several other telecommunications companies, including some Baby Bells, while selling its cable business. During this time, the company changed its name to SBC Communications. By 1998, the company was in the top 15 of the Fortune 500, and by 1999 the company was part of the Dow Jones Industrial Average (lasting through 2015).

Purchase of former parent and acquisitions (2005–2014)
In 2005, SBC purchased AT&T for $16 billion. After this purchase, SBC adopted the better-known AT&T name and brand, with the original AT&T Corp. still existing as the long-distance landline subsidiary of the merged company. The current AT&T claims the original AT&T Corp.'s history (dating to 1885) as its own. However, it retains SBC's 1983-2005 corporate structure. It also retains SBC's pre-2005 stock price history, and all regulatory filings prior to 2005 are for Southwestern Bell/SBC, not AT&T Corp.

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

Recent developments (2014–present)
AT&T purchased the Mexican carrier Iusacell in late 2014, and two months later purchased the Mexican wireless business of NII Holdings, merging the two companies to create AT&T Mexico.

AT&T also owns approximately a 2% stake in Canadian-domiciled entertainment company Lionsgate.

On July 13, 2017, it was reported that AT&T would introduce a cloud-based DVR streaming service as part of its effort to create a unified platform across DirecTV and its DirecTV Now streaming service, with U-verse to be added soon. In October 2018, it was announced that the service would launch in 2019.

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 next year.

, AT&T is the world's largest telecommunications company. AT&T is also the largest provider of mobile telephone services and the largest provider of fixed telephone services in the United States.

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. However, on April 18, just a day before the public debut of Vrio, AT&T canceled the IPO due to market conditions.

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, which holds the media assets it acquired in 2016; 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.

By 2019, AT&T had developed partnerships with health care providers to develop mobile health-related connectivity devices that aid in patient care. Key products include a telemetry device that monitors patient metrics, while toggling between WIFI and cellular connectivity.

In September 2019, Elliott Management published a letter outlining its proposal for a "value-creation opportunity" at AT&T. The activist investor announces that it owns $3.2 billion of AT&T stock (a 1.2% equity interest), and asserts that the company could increase its share value through divestiture of some assets.

AT&T Latin America
AT&T Latin America (formerly AT&T International, Inc.) is a wholly owned division of AT&T which operates in Mexico and 11 countries in Latin America and the Caribbean.

In 2017, AT&T announced a new AT&T International corporate division housing AT&T Mexico, DirecTV Latin America and their stakes of SKY Brazil and Sky Mexico, though the Sky stakes were sold to Comcast in 2018. On September 21, 2018, AT&T reclassified it four principal divisions which includes AT&T International which now have some assets moved out like the RSNs, an also merging Consumer Mobility, Technology and Business Mobility and renamed the company as AT&T Latin America.

Landline operating companies
Of the eight companies that were part of the Breakup of the Bell System, these five are a part of the current AT&T:
 * Ameritech, acquired by SBC in 1999
 * AT&T Corp., acquired by SBC in 2005
 * BellSouth, acquired by AT&T in 2006
 * Pacific Telesis, acquired by SBC in 1997
 * Southwestern Bell, rebranded as SBC Communications in 1995

Former operating companies
The following companies have become defunct or were sold under SBC/AT&T ownership:
 * Southern New England Telephone: sold to Frontier Communications in 2014
 * Woodbury Telephone: merged into Southern New England Telephone on June 1, 2007.

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; U S 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.

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 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." 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. Section 5.1 of AT&T's new terms of service now reads "AT&T respects freedom of expression and believes it is a foundation of our free society to express differing points of view. AT&T will not terminate, disconnect or suspend service because of the views you or we express on public policy matters, political issues or political campaigns."

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. The Department of Justice has stated it will intervene in this lawsuit by means of State Secrets Privilege.

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.

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. 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.'"

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.=

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.

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.

AT&T has a one star privacy rating from the Electronic Frontier Foundation.

Intellectual property filtering
In January 2008, the company reported plans to begin filtering all Internet traffic which passes through its network for intellectual property violations. Commentators in the media have speculated that if this plan is implemented, it would lead to a mass exodus of subscribers leaving AT&T, although this is misleading as Internet traffic may go through the company's network anyway. Internet freedom proponents used these developments as justification for government-mandated network neutrality.

Discrimination against local Public-access television channels
AT&T has been 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".

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. 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."

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".

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. These email addresses could be accessed without a protective password. Using a script, Goatse Security collected thousands of email addresses from AT&T. Goatse Security informed AT&T about the security flaw through a third party. 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. Praetorian Security Group criticized the web application that Goatse Security exploited as "poorly designed".

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 centres in Mexico, Colombia and the Philippines.

Trademark violation
In June 2016, Citigroup sued AT&T for trademark infringement, false designation of origin, and unfair competition. The company had recently established a loyalty program under the brand AT&T Thanks, which Citigroup claims would cause consumer confusion as an infringement of its "ThankYou" and "Citi ThankYou" marks due to similar wording and visual design. Citi, which also provides a co-branded credit card for AT&T that links with its ThankYou rewards program, sought unspecified damages and the expungement of AT&T's trademark registration.

The suit was dismissed in August 2016, with a judge ruling that there was a low likelihood of confusion between the two marks because the companies fall within different industries, and that consumers who use loyalty programs would be able to "clearly take into account the attributes associated with the products they purchase" and, thus, be able to distinguish them.
