WISCONSIN BELL

'Wisconsin Bell, Inc.' (known as 'Wisconsin Telephone Co.' before 1984) is the name of the Bell Operating Company serving Wisconsin. They were a wholly owned subsidiary of 'AT&T Inc.'.
Their headquarters is at 722 North Broadway, Milwaukee, WI. After the 1984 Bell System Divestiture, Wisconsin Bell became a part of Ameritech, one of the 7 original Bell Regional Holding Companies. The Wisconsin Bell name continued to be used until January, 1993, when they dropped all of their individual Bell Operating Company names in favor of using their corporate name, Ameritech, for marketing purposes.
In 1998, Ameritech sold 19 Wisconsin Bell exchanges, primarily located in central and northern Wisconsin, to CenturyTel.
After being held by AT&T (pre-1984), Ameritech, and SBC, as of 2005, they are now part of the "new" AT&T.
