AT&T Inc. began its history as Southwestern Bell Telephone Company, which was a subsidiary of the Bell Telephone Company founded by Alexander Graham Bell in 1880. Bell Telephone Company evolved into American Telephone and Telegraph Company in 1885 which had since rebranded to AT&T Corporation. Following the 1982 United States v. AT&T antitrust lawsuit, this resulted in the divestiture of AT&T Corp.'s ("Ma Bell") subsidiaries or Regional Bell Operating Companies ("Baby Bells"), resulting in several independent companies including Southwestern Bell Corporation. Southwestern Bell changed its name to SBC Communications Inc. in 1995. In 2005, SBC purchased former parent AT&T Corporation and took on its branding, with the merged entity naming itself AT&T Inc. and using the iconic AT&T logo and stock-trading symbol. In 2006, AT&T Inc. acquired BellSouth, the last independent Baby Bell, making their formerly joint venture Cingular Wireless (which had acquired AT&T Wireless in 2004) wholly owned and rebranding it to AT&T Mobility.
