WJXT (channel 4) is an independent television station in Jacksonville, Florida, United States. It is owned by Graham Media Group alongside CW affiliate WCWJ (channel 17). Both stations share studios at 4 Broadcast Place on the south bank of the St. Johns River in Jacksonville, while WJXT's transmitter is located on Anders Boulevard in the city's Killarney Shores section. History As a CBS affiliate WJXT originally signed on the air on September 15, 1949, as WMBR-TV. It was Jacksonville's first television station, the second television station in Florida and a primary CBS affiliate on VHF channel 4 after WTVJ (also on channel 4, now an NBC owned-and-operated station on channel 6) in Miami–Fort Lauderdale. The station was co-owned alongside WMBR radio (1460 AM, now WQOP; and 96.1 FM, now WEJZ). Though the station was originally a primary CBS affiliate, it also maintained secondary affiliations with NBC, ABC and the DuMont Television Network. In 1953, the WMBR stations were purchased by The Washington Post Company. WMBR-TV dropped the DuMont affiliation in 1955, less than a year before the network ceased operations. Since its only competition in the Jacksonville market came from UHF station WJHP-TV (which signed on in 1953 and went dark three years later), channel 4 had a virtual television monopoly in northern Florida until September 1957, when it lost the NBC affiliation to upstart WFGA (channel 12, now WTLV). The Washington Post Company sold WMBR-AM-FM in 1958, while it kept the television station, whose callsign it changed to the current WJXT. WJXT remained a primary CBS and secondary ABC affiliate until WJKS-TV (channel 17, now CW sister station WCWJ) took the ABC affiliation upon its sign-on in February 1966, leaving WJXT exclusively with CBS. For much of its tenure as a CBS affiliate, WJXT was the only station affiliated with the network that was located between Savannah, Georgia, and Orlando, Florida and was thus carried on many cable systems between Jacksonville and Orlando. In 1973, WJXT's FCC license renewal was challenged by supporters of President Richard Nixon following the Watergate coverage of his administration by The Washington Post, whose parent company owned the station. Robert W. Schellenberg, WJXT's general manager, successfully led the effort to defeat the opposition. In 2001, WJXT was awarded the local broadcast rights to Jacksonville Jaguars preseason football games, replacing WTLV as the official station for the NFL franchise (WTLV had carried preseason games and
