AT&T Inc. is the largest provider of both local and long distance telephone services, DSL Internet access and wireless service in the United States with 71.4 million wireless customers and more than 150 million total customers

In 2005, "Baby Bell" SBC Communications Inc. purchased former "Ma Bell" AT&T Corporation and then changed the name of the company after the merger to the more iconic AT&T moniker and the T stock-trading symbol (for "telephone").

The current AT&T includes eleven of the original Bell Operating Companies, and the original long distance division. While it reconstitutes much of the former Bell System, AT&T Inc. lacks the vertical integration of the historic AT&T Corp. which prompted the antitrust suit and breakup in 1984.

The company was honored at the 2008 Technology & Engineering Emmy Awards for development of coaxial cable technology.
