Overview
Ameritech was created as a holding company that owned five former Bell System companies in the Midwest. Under its umbrella were:
- Illinois Bell Telephone Company
- Indiana Bell Telephone Company, Inc.
- Michigan Bell Telephone Company
- Ohio Bell Telephone Company
- Wisconsin Bell, Inc.
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".

SBC and Ameritech officially merged on October 8, 1999. Prior to the merger, Ameritech's Chairman and CEO was Richard Notebaert, who later (in 2002) became CEO of competitor Qwest.
The end of the Ameritech name
On January 15, 2003, SBC Communications changed its d.b.a. names, changed the legal name of Ameritech Corp. to SBC Teleholdings, Inc., which began doing business as SBC Midwest. On January 15, 2006, d.b.a names were again changed to align with SBC's assumption of the AT&T brand identity following its acquisition of AT&T Corp. the previous year, and Ameritech was again renamed, becoming AT&T Teleholdings, Inc.[4] 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".
In 2006, the holding companies
