change, channel 2 became a primary affiliate of the higher-rated CBS network instead. KDKA-TV retained secondary affiliations with NBC until WIIC-TV (channel 11, now WPXI) signed on in 1957, and ABC until WTAE-TV (channel 4) signed on in 1958. Despite the ending of its commercial VHF monopoly, KDKA-TV did welcome competitor WIIC-TV on the air. KDKA-TV became the flagship station of Westinghouse's broadcasting arm, Group W. During the late 1950s, KDKA-TV was briefly affiliated with the NTA Film Network, sharing the affiliation with WTAE-TV, WIIC-TV, and WQED. On November 22, 1963, newscaster Bill Burns provided almost three hours of live coverage after the shooting of President John F. Kennedy. In 1994, Westinghouse was looking to make a group-wide affiliation deal for its stations as part of a larger plan to transform itself into a major media conglomerate after WJZ-TV lost its ABC affiliation to Scripps-owned WMAR-TV in an affiliation deal spurred by Fox's affiliation deal with New World Communications. Westinghouse negotiated with NBC and CBS for a deal. Had Westinghouse signed with NBC, KDKA-TV would affiliate itself with NBC 40 years after passing up the network, with the CBS affiliation going to WPXI, who had originally intended to affiliate itself with CBS until the NBC-Westinghouse feud started as well as channel 11's own sign-on problems in the 1950s. While NBC (the highest-rated network during much of the 1980s and 1990s) offered more money, CBS was interested in the programming opportunities Westinghouse offered, due to its own stagnation in programming at the time. CBS also offered a potential merger of their respective radio networks down the road (which ultimately happened), while NBC had abandoned radio in 1987. Ultimately, Westinghouse signed a long-term deal with CBS to convert the entire five-station Group W television unit to a group-wide CBS affiliation, making the Pittsburgh market one of the few major markets that were not affected by the affiliation switches. In 1995, Westinghouse acquired CBS, making KDKA-TV a CBS owned-and-operated station, after four decades as being simply a CBS affiliate. In 1997, Westinghouse became CBS Corporation, which would then merge with Viacom (which, ironically, has been Paramount's parent since 1994) in 2000, making KDKA-TV a sister station with Pittsburgh UPN affiliate WNPA-TV (channel 19, now CW station WPCW). Five years later, Viacom became the new CBS Corporation and spun off a new Viacom. In August 2007, KDKA-TV unveiled a new image campaign, entitled "Your
