. Only three years earlier, Western Union had turned down Gardiner Hubbard's offer to sell it all rights to the telephone for $100,000 ($ in 2009 dollars). In 1880, the management of American Bell created what would become AT&T Long Lines. The project was the first of its kind to create a nationwide long-distance network with a commercially viable cost-structure. This project was formally incorporated into a separate company named American Telephone and Telegraph Company on March 3, 1885. Starting from

Monopoly

As a result of a combination of regulatory actions by government and actions by AT&T, the firm eventually gained what most regard as

regulators. To avoid antitrust action, in a deal with the government, Vail agreed to the

. G.W. Brock says in ''The Telecommunications Industry: The Dynamics Of Market Structure'', " heprovision allowed Bell and the independents to exchange telephones in order to give each other geographical monopolies. So long as only one company served a given geographical area there was little reason to expect price competition to take place." AT&T focused on purchasing companies within specific geographic areas that increased its effective control of the telephone system market, while selling its less-desirable and previously acquired companies to independent buyers. Also included in the Kingsbury Commitment was the requirement that AT&T allow competitors to connect through its phone lines, which reduced the incentive of these companies to build competing long-distance lines.

allies and partners in RCA were angered when the two companies' research on tubes began to overlap, and there were many patent disputes. Around 1917, the idea that everyone in the country should have phone service and that the government should promote that began being discussed in government. AT&T agreed, saying in a 1917 annual report: "A combination of like activities under proper control and regulation, the service to the public would be better, more progressive, efficient, and economical than competitive systems." In 1918 the federal government nationalized the entire telecommunications industry, with national security as the stated intent. Rates were regulated so that customers in large cities would pay higher rates to subsidize those in more remote areas. Vail was appointed to manage the telephone system with AT&T being paid a percentage of the telephone revenues. AT&T profited well from the nationalization arrangement which ended a year later. States then began regulating rates so that those in rural areas would not have to pay high prices, and the competition was highly regulated or prohibited in local markets. Also, potential competitors were forbidden from installing new lines to compete, with state governments wishing to avoid "duplication." The claim was that telephone service was a "

," meaning that one firm could better serve the public than two or more. Eventually, AT&T's market share amounted to what most would regard as a monopolistic share. AT&T, RCA, and their patent allies and partners finally settled their disputes in 1926 by compromise. AT&T decided to focus on the telephone business as a communications common carrier and sold its broadcasting subsidiary

In return, RCA signed a service agreement with AT&T, ensuring any radio network RCA started would have transmission connections provided by AT&T.

In 1949, the Justice Department filed an antitrust suit aimed at forcing the divestiture of Western Electric, which was settled seven years later by AT&T's agreement to confine its products and services to common carrier telecommunications and license its patents to "all interested parties." A key effect of this was to ban AT&T from selling computers despite its key role in electronics research and development. Nonetheless, technological innovation continued.

. Like most telephones of the time in the United States, Western Electric-made phones were owned not by individual customers, but by local Bell System telephone companies — all of which were in turn owned by AT&T, which also owned Western Electric itself. Each phone was leased from AT&T on a monthly basis by customers, who generally paid for their phone and its connection many times over in cumulative lease fees. This monopoly made millions of extra dollars for AT&T, which had the secondary effect of greatly limiting phone choices and styles. AT&T strictly enforced policies against buying and using phones by other manufacturers that had not first been transferred to and re-rented from the local Bell monopoly. Many phones made by Western Electric thus carried the following disclaimer permanently molded into their housings: "BELL SYSTEM PROPERTY — NOT FOR SALE." Telephones were also labeled with a sticker marking the Bell Operating Company that owned the telephone. In 1968, the

. In the 1980s, after some consumers began buying phones from other manufacturers anyway, AT&T changed its policy by selling customers the phone's housing, retaining ownership of the mechanical components — which still required paying AT&T a monthly leasing fee. For most of the 20th century, AT&T subsidiary AT&T Long Lines thus enjoyed a near-total monopoly on long-distance telephone service in the United States.

Erosion of "a natural monopoly"

For many years, AT&T had been permitted to retain its monopoly status under the assumption that it was a

decision that allowed third-party equipment to be connected to the AT&T telephone network. The rise of cheap microwave communications equipment in the 1960s and 1970s opened a window of opportunity for competitors — no longer was the acquisition of expensive rights-of-way necessary for the construction of a long-distance telephone network. In light of this, the FCC permitted MCI (Microwave Communications, Inc) to sell communication services to large businesses. This technical-economic argument against the necessity of AT&T's monopoly position would hold for a mere fifteen years until the beginning of the fiber-optics revolution sounded the end of microwave-based long distance.


Breakup

The rest of the telephone monopoly lasted until January 8, 1982, the date of settlement of '' United States v. AT&T'', a 1974

s". With the American consumer's new ability to purchase phones outright, AT&T and the Bell System lost the considerable revenues earned from phone leasing by local Bell companies. Forced to compete with other manufacturers for new phone sales, the aging Western Electric phone designs still marketed through AT&T failed to sell, and Western Electric eventually closed all of its U.S. phone manufacturing plants. AT&T, reduced in value by about 70%, continued to run all its long-distance services through AT&T Communications (the new name of AT&T Long Lines), although it lost some market share in the ensuing years to competitors MCI and Sprint.

. In 2002, it closed down the research part of the lab. Also in 1999, AT&T paid US$5 billion to purchase IBM's Global Network business, which became AT&T Global Network Services, LLC. As part of the purchase agreement, IBM granted AT&T a five-year, US$5-billion contract to handle much of IBM's networking needs, and AT&T outsourced some of its application processing and data management work to IBM. IBM also committed to billing and installation for AT&T's long-distance customers in a 10-year deal valued at US$4 billion; and assumed management of AT&T's data processing centers. With long-distance rates falling and the market for telecommunications services overall weakening, AT&T could not sustain the debt it had incurred in these ventures. Moreover, the cost of upgrading TCI's equipment to handle two-way communications proved far higher than pre-merger estimates. AT&T undertook a major reorganization in October 2000, moving its mobile phone and broadband units into separate companies, to allow each unit to raise capital independently. On July 9, 2001, it spun off

. In 2004, the U.S. government eliminated equal access regulations that allowed long-distance phone companies to access the networks owned by the regional Bell carriers at fixed rates. This ultimately caused AT&T to move away from the residential telephone business — declaring in the process that it would no longer market residential telephone service. Instead, its residential focus shifted to offering a voice service over a broadband Internet connection called AT&T CallVantage.


Rise of SBC

One of the new companies formed by the breakup of AT&T was Southwestern Bell Corporation. This company grew continuously over the years until it acquired AT&T in 2005. After this acquisition, SBC took on AT&T's name and branding, and this is the company known as AT&T today.


1984–2001: Southwestern Bell Corporation

American Telephone and Telegraph Company officially transferred full ownership of Southwestern Bell Telephone Company to Southwestern Bell Corporation on January 1, 1984. It had three other subsidiaries: Southwestern Bell Publications, Inc., a directory publisher; Southwestern Bell Mobile Systems, Inc., in the business of mobile telephone service; and Southwestern Bell Telecommunications, Inc., focusing on marketing phone equipment to business customers. The holding company's new president was Zane Edison Barnes. In 1987, SBC bought

1995–2000: Changes to the company

In 1995, Southwestern Bell Corp. became SBC Communications. They then combined the Southwestern Bell Telecom division (which made telephone equipment) into the company, due to new FCC rules. In 1996, SBC announced it would acquire Pacific Telesis Group, a

(RBOC) in California and Nevada. 1997 brought rumors of a proposed merger between AT&T Corporation (the USA's largest long-distance provider) and SBC (the USA's largest local provider). The FCC disapproved of the merger, and it came to end. Later in 1997, SBC sold its last two cable companies, exiting the cable telecom field. In January 1998, SBC announced it would take over the Southern New England Telephone Company (SNET) for $4.4 billion in stock (the FCC would approve in October 1998). SBC also won a court judgment that would make it easier for RBOCs to enter the long-distance phone service, but it was being challenged by AT&T and the FCC. In May 1998, Ameritech and SBC announced a $62 billion merger, in which SBC would take over Ameritech. After making several organizational changes (such as the sale of Ameritech Wireless to GTE) to satisfy state and federal regulators, the two merged on October 8, 1999. The FCC later fined SBC Communications $6 million for failure to comply with agreements made in order to secure approval of the merger. SBC became the largest RBOC until the

2007–2008: restructuring


Transition to new media

In June 2007, AT&T's new chairman and CEO, Randall Stephenson, discussed how wireless services are the core of "The New AT&T". With declining sales of traditional home phone lines, AT&T plans to roll out various new media such as Video Share,

Interwise was a leading global provider of voice, Web and video conferencing services to businesses. On October 9, 2007, AT&T purchased 12 MHz of spectrum in the prime 700 MHz spectrum band from privately held Aloha Partners for nearly $2.5 billion; the deal was approved by the FCC on February 4, 2008.

for $39 billion from Deutsche Telekom. The deal would have seen the addition of 33.7 million subscribers, making AT&T Mobility the largest mobile phone company in the United States. AT&T Mobility would have had a 43% market share of mobile phones in the U.S. making AT&T Mobility significantly larger than any of its competitors. Regulators questioned the effects such a deal would have had on both competitors and consumers. AT&T CEO Randall Stephenson however stated that the merger would increase network quality and would lead to large savings for the company. AT&T stated it may have had to sell some assets to gain approval from regulators, but claimed to have done their "homework" on regulations. Reaction to the announced merger generated both support as well as opposition among various groups and communities. The merger gained support from a wide number of civil rights, environmental, and business organizations. These include the

also voiced support for the merger. These organizations pointed to AT&T's commitment to labor, social, and environmental standards. Many of these organizations also cited how the merger is likely to accelerate 4G wireless deployment, thus helping underserved communities such as rural areas and disadvantaged urban communities. According to the NAACP, the merger would have "advance increased access to affordable and sustainable wireless broadband services and in turn stimulate job creation and civic engagement throughout our country." By August 2, 2011, the governors of 26 states had written letters supporting the merger. On July 27 the attorneys general of Utah, Alabama, Arkansas, Georgia, Kentucky, Michigan, Mississippi, North Dakota, South Dakota, West Virginia, and Wyoming sent a joint letter of support to the FCC. By August 2011 state regulatory agencies in Arizona and Louisiana approved the acquisition. A diverse group of industry and public-interest organizations opposed AT&T's merger with T-Mobile.

and members of Congress. These organizations feared that the merger will raise prices and stifle innovation by consolidating so much of the wireless industry in one company. Free Press and Public Knowledge started letter-writing campaigns against the deal. Internet companies were generally skeptical of the merger because it leaves them with fewer counter-parties to negotiate with for getting their content and applications to customers.

among its members, opposed the merger. "A deal like this, if not blocked on antitrust grounds, is of deep concern to all the innovative businesses that build everything from apps to handsets. It would be hypocritical for our nation to talk about unleashing innovation on one hand and then stand by as threats to innovation like this are proposed," said Ed Black, head of CCIA. On April 21, 2011, AT&T defended its proposed acquisition of T-Mobile USA before a U.S. Senate committee, saying the combined company would deliver high-speed wireless services to 97 percent of Americans and provide consumer benefits such as fewer dropped calls. As part of the original negotiations, if AT&T's acquisition of T-Mobile USA were to be rejected by federal regulators, AT&T would need to pay $6 billion, including $3 billion in cash, to T-Mobile USA's parent company Deutsche Telekom. On August 31, 2011, the Department of Justice officially filed a lawsuit in the United States District Court for the District of Columbia seeking to block the acquisition. On November 30, 2011, the FCC allowed AT&T to withdraw their merger, saving both carriers from divulging documentation about internal operations. The FCC cited job loss and higher consumer prices as reasons to deny the merger. On December 19, 2011, AT&T announced that it would permanently end its merger bid after a "thorough review of its options". As per the original acquisition agreement, T-Mobile will receive $3 billion in cash as well as access to $1 billion worth of AT&T-held wireless spectrum.
