AT&T Teleholdings, Inc.
Type Private (subsidiary of AT&T Inc.)
Founded 1983
Headquarters Chicago, IL, USA
Industry Telecommunications
Products Telephone, Internet, Television
Parent SBC Communications/AT&T Inc. (1999-present)

AT&T Teleholdings, Inc., formerly Ameritech Corporation (and before that American Information Technologies Corporation) is a U.S. telecommunications company that arose out of the 1984 AT&T divestiture. Ameritech was one of seven Regional Bell Operating Companies divested.

Ameritech was created as a holding company; under its umbrella were:

For Ameritech's first nine years, it maintained these Bell brands inherited from the Bell System—though public displays of the Bell companies' names were often captioned "An Ameritech Company". In January 1993, Ameritech officially retired the Bell brands and marketed itself with solely the Ameritech name across all five states in its territory. It added "d/b/a Ameritech (state)" to the names of its Bells to communicate brand unity.

Ameritech also owned Ameritech Cellular, a wireless company that operated cellular networks in many of the major cities of these states. Ameritech Cellular was previously called Ameritech Mobile Communications.

Prior to its merger with SBC Communications, Ameritech's corporate headquarters were in a leased space above the Chicago Mercantile Exchange on floors 34 through 39 of 30 S Wacker Dr, Chicago IL. Further corporate offices were located at 225 W Randolph St, Chicago IL (formerly "The Illinois Bell Building") and 2000 W. Ameritech Center Drive, Hoffman Estates, IL ("The Ameritech Center"). It was traded on the NYSE under the "AIT" symbol.

Merger with SBC Communications

In May 1998, Ameritech announced its intent to merge with SBC Communications. This brought great concern to Federal and state regulators, who in turn didn't approve the merger until SBC and Ameritech agreed to several conditions [1] to ensure adequate competition. Most notably, regulators required:

  • that the merged company offer local phone service in thirty markets outside of its home territory within thirty months of the merger (i.e. by April 2002) or pay a $1.18B penalty
  • and that Ameritech Cellular assets in Chicago be sold to GTE. Since SBC already had a majority stake in a large mobile provider (Cingular), the merged company, if it were to operate Ameritech Cellular and Cingular both, would have wielded too much market power.

SBC and Ameritech officially merged on 1999-10-08. Prior to the merger, Ameritech's Chairman and CEO was Richard Notebaert, who later (in 2002) became CEO of competitor Qwest.

The end of Ameritech

On January 15, 2003, SBC Communications changed its d/b/a names, and then changed the legal name of Ameritech Corp. to SBC Teleholdings, Inc., and would begin doing business as SBC Midwest. On January 15, 2006, AT&T changed its d/b/a names, and Ameritech was again renamed, becoming AT&T Teleholdings, Inc.[1] and began doing business as AT&T Midwest.

Several Ameritech subsidiaries remain legally named "Ameritech", such as Ameritech Advanced Services; however, they do business as "AT&T Advanced Solutions".
