AT&T Corporation

AT&T Corp., originally American Telephone and Telegraph Company, is an American telecommunications company that provides voice, video, data, and Internet telecommunications and professional services to businesses, consumers, and government agencies. During its long history, AT&T was at times the world's largest telephone company, the world's largest cable television operator, and a regulated monopoly. At its peak in the 1950s and 1960s, it employed one million people and its revenue was roughly $300 billion annually in 2006 dollars.

In 2005, AT&T was purchased by Baby Bell SBC Communications for more than $16 billion ($19 billion in present-day terms). SBC then rebranded itself as AT&T Inc. Today, AT&T Corporation continues to exist as the long distance subsidiary of AT&T Inc., and its name occasionally shows up in AT&T press releases.
