The AT&T; logo rises once again on Monday when the Cingular brand goes the way of SBC in a marketing campaign with an undisclosed budget (an estimated $1 billion was spent on SBC’s changeover to AT&T; last year). In 2004, AT&T; Wireless (originally McCaw, bought and then spun off by the original AT&T;) was bought by Cingular, owned by SBC and BellSouth. Then SBC merged with AT&T; and bought BellSouth. SBC took the name AT&T; and then completed its BellSouth acquisition on December 29th, becoming the full owner of Cingular which is now taking the AT&T; name too. Confused? Don’t bother figuring it all out; it’s too complicated to turn up as a trivia question anywhere. (NY Times, Seattle Times)
