AT&T Inc. (NYSE: T) is the largest provider of both local and long distance telephone services, wireless service, and DSL Internet access in the United States. The current AT&T, which is based in San Antonio, Texas, United States, is the rechristened SBC Communications, following the purchase of its former parent company, American Telephone & Telegraph. As a part of the merger, SBC shed its name and took on the iconic AT&T moniker and the T stock-trading symbol (for "telephone"). The corporation is considered SBC renamed.

Since the break-up of American Telephone and Telegraph Company in 1984, most of its major components have merged into three major US telecommunications groups: Verizon, Qwest, and AT&T Inc. Most of these companies are made up primarily of former components of American Telephone and Telegraph Company. For AT&T Inc, these include many Bell Operating Companies and the long distance division.

AT&T Inc. was founded in 1983 as Southwestern Bell Corporation, headquartered in St. Louis, Missouri. It was one of the seven original Regional Bell Operating Companies, or "Baby Bells." The company — a holding company for Southwestern Bell Telephone Company — was created as a result of U.S. antitrust action against American Telephone & Telegraph in 1983. It took full control of Southwestern Bell Telephone on January 1, 1984.

In 1993 Southwestern Bell Corp. moved its headquarters to San Antonio, Texas, and, during its annual meeting of stockholders in 1995, the company announced that its name would be changed to SBC Communications, Inc. The name change was an effort to reinforce the company's national and global reach and the company not only stated that "SBC" wasn't an acronym for Southwestern Bell Corporation, but that it did not stand for anything at all.

SBC then proceeded (as permitted by the Telecommunications Act of 1996) to acquire fellow Baby Bell Pacific Telesis, the Regional Bell operating company serving Nevada and California, in 1997 and the former independent Bell System franchise SNET (Southern New England Telephone).

SBC then announced plans to acquire Ameritech, the Regional Bell operating company serving Illinois, Indiana, Michigan, Ohio, and Wisconsin, and told the FCC that it would allow competitors access to local markets where it had had a monopoly if the FCC would allow them to acquire Ameritech. The FCC agreed and in May 1998, SBC and Ameritech announced the merger would move forward. 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.

In 2002, SBC ended marketing its operating companies under different names, and simply opted to give its companies different doing business as names based on the state (a practice already in use by Ameritech since 1993), and it gave the holding companies it had purchased d/b/a names based on their general region.
