What is "mediaone"

Comcast MO Group, Inc., formerly MediaOne Group, Inc. and originally US WEST, Inc., was a cable company that was founded in 1983 as one of the original Regional Bell Operating Companies. Founded under the Modification of Final Judgement (United States v. Western Electric Co., Inc. 552 Fed. Supp. 131), a case related to the antitrust breakup of AT&T, it began expansion into the cable television field and later spun off U S WEST Communications and US WEST Dex into a "new" US WEST in 1998.
