AT&T Inc
AT&T Inc. (formerly SBC Communications) was formed in 2005 when SBC bought AT&T Corp., for some $16 billion, creating the largest telecommunications outfit in the US (after the merger, SBC adopted the more familiar AT&T moniker). The new AT&T has more than 50 million switched access lines in service; its biggest markets are California, Texas, and Illinois. The company has combined its US wireless operations with those of BellSouth to form Cingular Wireless, the leading US wireless carrier with more than 50 million subscribers after its acquisition of former rival AT&T Wireless. It is also a market leader in providing DSL broadband services with some 6 million subscribers.
