US West, Inc. was one of seven Regional Bell Operating Companies (RBOC's, also referred to as "Baby Bells"), created in 1983 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. US West provided local telephone and intraLATA long distance services, data transmission services, cable television services, wireless communications services and related telecommunications products to defined areas in Arizona, Colorado, Idaho, Iowa, Minnesota, Montana, Nebraska, New Mexico, North Dakota, Oregon, South Dakota, Utah, Washington, and Wyoming. US West was a public company traded on the New York Stock Exchange under the ticker symbol "USW" with headquarters at 1801 California Street in Denver, Colorado. Until 1990, US West was a holding company with three Bell Operating Companies: Mountain States Telephone & Telegraph (or Mountain Bell, based in Denver, Colorado); Northwestern Bell, based in Omaha, Nebraska; and Pacific Northwest Bell, based in Seattle, Washington. In 1988, the three companies began doing business under the US West Communications name. On January 1, 1991, Northwestern Bell and Pacific Northwest Bell were legally merged into Mountain Bell which was renamed US West Communications, Inc. US West was the first RBOC to consolidate its Bell Operating Companies (the other was BellSouth). US West merged with Qwest Communications International Inc. on June 30, 2000 and over time the US West brand was replaced by the Qwest brand. Qwest Communications International Inc. merged with CenturyLink on April 1, 2011 and the Qwest brand was replaced by the CenturyLink brand.〔(CenturyLink and Qwest Agree to Merge )〕 == Accomplishments == US West became a pioneer in the introduction and rapid system-wide implementation of telephone technologies designed by Bellcore (now Telcordia Technologies) in the 1980s and 1990s. Their lead in this push became one that many other Regional Bell Operating Companies had to scramble to keep up with. US West's success in this endeavor was for multiple reasons which included their then-innovative use of "test-markets" for staggered roll-outs of new calling features in middle-sized cities such as Boise, Idaho, Minneapolis, Minnesota, and Phoenix, Arizona before releasing them on a wider scale. (They were the first communications provider to use this strategy called beta-testing, a term used for many years in the software development industry). Their geographic presence featured telephone switching equipment that had been constructed fairly recent to the time frame, thereby requiring fewer upgrades. Their service area was also experiencing population growth at a tremendous rate, tripling their subscriber-base in a short time and increasing revenues. US West Communications was the first local telephone company to offer Caller ID service in 1991, nearly four years before any other local telco could do so. They were the first US telco to upgrade their PSTN to electronic switching before 1990 and they were the first to offer residential and business ISDN and later, DSL services to their customers by 1997. US West was also briefly in the cable business with its purchase of Continental Cablevision in 1996, creating MediaOne (which was later spun off). US West also participated in a joint venture agreement with Time Warner Cable to form Time Warner Communications (now TW Telecom) in 1993- it also purchased a 26% stake in TW's entertainment operations, which was subsequently passed to MediaOne, AT&T, and Comcast, with that company selling back the stake in 2003. As a result of its rapid "bring-to-market" abilities and continued success in the advances in technology, the company quickly adopted a new slogan— "Life's better here." 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「US West」の詳細全文を読む スポンサード リンク
