During the Bell System's 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 ranged between US$3 billion in 1950 ($41.3 billion in present-day terms) and $12 billion in 1966 ($117 billion in present-day terms).
In 2005, AT&T was acquired by "Baby Bell" and former subsidiary SBC Communications for more than $16 billion ($25 billion in present-day terms). SBC then changed its name to AT&T Inc., with AT&T Corporation continuing to exist as the long distance subsidiary.
