Question: How long had Multimedia Cablevision been established before it began servicing the adjacent areas of Oklahoma City? Passage 1:The service launched as multichannel television service was beginning to be established in Oklahoma City and surrounding communities, with several cable providers and an MMDS operation having already commenced service in the metropolitan area. Cox Cable and Pan Oklahoma Communications were in the process of wiring the Oklahoma City core. (When the two providers commenced operations in April 1980, Cox serviced the western half of the city and Pan Oklahomaan African American-owned buildout venture that was majority owned by Cox, which would acquire the company outright in December 1983provided service to northeastern Oklahoma City, from Western Avenue eastward, and the bordering unincorporated suburb of Forest Park.) MMDS service was also provided throughout the city via the single-channel TVQ/Movie Systems, Inc., which began operations in October 1978, providing programming from HBO, Superstation WTBS and supplementary content from eventual KAUT sister station WGN-TV/Chicago (consisting of Chicago Cubs Major League Baseball games) and Nickelodeon (from which TVQ provided additional children's programming until June 1981). Multimedia Cablevision also began providing service to select suburbs and adjacent areas of Oklahoma City as early as 1972 (eventually including among others, Bethany, Edmond, Guthrie, Del City, Choctaw, Harrah, Moore, Nichols Hills, Norman and Yukon), except for Midwest City, whichin areas outside of the Multimedia-serviced Tinker Air Force Basewas served by American Cablevision (which had began operations in 1979, and would be absorbed into Multimedia's Central Oklahoma operations in May 1984). These suburban services were also in the process of expanding their lineup of cable-originated channel offerings.
