had already taken control of channel 4's operations that March, and changed its call letters to KMOX-TV in reference to its new radio sister. The following April, channel 11 signed on as independent station KPLR-TV. In July 1968, CBS opened a new studio and office facility in downtown St. Louis to house the KMOX stations, which until that point had been operating from separate locations (KMOX radio was headquartered near Forest Park). Channel 4 moved from Cole Street into the new facility, known as One Memorial Drive, and remains there to the present day; the Cole Street studio was soon acquired by KDNL-TV (channel 30), which has operated from there since it signed on in June 1969. KMOX-TV was the host station for the 1983 Miss Universe Pageant, which was held at the now-demolished Kiel Auditorium. Viacom ownership By late 1985, CBS was in rough financial straits, an after-effect of successfully fending off a hostile takeover attempt by Ted Turner the year before. CBS spent the latter portion of 1985 repurchasing a large portion of its stock to help block the Turner takeover. Once Turner sold his stock, CBS was saddled with significant debt and needed to raise money. Not long after Laurence Tisch became the company's chairman, CBS decided to sell KMOX-TV, at the time its smallest owned-and-operated television station by market size. On May 16, 1986, the original iteration of Viacom, the former CBS Inc. subsidiary and future parent company, completed its $122.5 million purchase of the station; so as to comply with an FCC regulation in place at the time that prohibited TV and radio stations in the same market but with different ownership from having the same callsigns, KMOX-TV's callsign was slightly modified to the present KMOV almost a month later on June 18. Despite the sale, channel 4's operations continued to be based alongside KMOX radio at their downtown studios on Memorial Drive; KMOX would relocate from that building in 2012. Viacom purchased Paramount Pictures in 1993, and merged its five-station group (KMOV; WHEC-TV in Rochester, New York; WNYT in Albany, New York; WVIT in New Britain, Connecticut; and KSLA-TV in Shreveport, Louisiana) into the Paramount Stations Group. However, in 1994, the company decided to divest itself of all of its major network affiliates to focus on stations that carried its then-upstart United Paramount Network (UPN), which would start up service on January 16, 1995.
