Southwestern Bell Corporation was one of seven Regional Bell Operating Companies that were incorporated in 1983 by AT&T Corp following the break-up of the original AT&T as a result of the United States v. AT&T antitrust suit. The company changed its name in 1995 to SBC Communications Inc. and again in 2005 to AT&T Inc. after it purchased its former parent company, AT&T Corporation. The newly merged company took on the iconic AT&T logo and stock-trading symbol (NYSE: T, for "telephone").
The current AT&T reconstitutes much of the former Bell System and includes ten of the original 22 Bell Operating Companies along with one it partially owned (Southern New England Telephone), and the original long distance division. The company is headquartered in downtown Dallas, Texas
