AT&T

This article is about the current AT&T. For the 1885-2005 company, see American Telephone & Telegraph. For the wireless provider subsidiary, see AT&T Mobility. For the 1910s British airline, see Aircraft Transport and Travel.
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. AT&T is based in San Antonio, Texas, United States. Formerly SBC Communications, Inc., the company shed its name and took on the iconic AT&T moniker and the T stock-trading symbol (for "telephone") after its acquisition of AT&T Corporation.
Since the break-up of American Telephone and Telegraph Company in 1984, most of the companies spun off from it (the "Baby Bells") 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 the new AT&T, these include many Bell Operating Companies and the long distance division.
