AT&T Worldnet ISP

In 2004, AT&T announced it would no longer seek traditional customers for landline local & long distance services, and upon the heels of the announcement, AT&T introduced AT&T CallVantage service, a VoIP telephone service, and a new DSL internet service. AT&T Worldnet, upon introduction of the new services, began to lose speed in customer growth, since AT&T DSL was more heavily promoted.

In 2005, SBC Communications purchased AT&T and changed its name to AT&T, Inc.; AT&T Worldnet continued to be provided by AT&T Corp., as a division of AT&T Inc until April 2008 when it was merged into AT&T Yahoo! DSL (formerly SBC Yahoo! DSL), AT&T's central internet service to its local telephone customers.
