WDBJ (channel 7) is a television station licensed to Roanoke, Virginia, United States, serving as the CBS affiliate for the Roanoke–Lynchburg market. It is owned by Gray Television alongside Danville-licensed MyNetworkTV affiliate WZBJ, channel 24 (and its Lynchburg-licensed Class A translator WZBJ-CD, channel 19). WDBJ and WZBJ share studios on Hershberger Road in northwest Roanoke; through a channel sharing agreement, the two stations transmit using WDBJ's spectrum from an antenna on Poor Mountain in Roanoke County. History Early history WDBJ-TV first signed on the air on October 3, 1955. It was owned by the Times-World Corporation, publishers of the Roanoke Times and Roanoke World-News, alongside WDBJ radio (960 AM, now WFIR; and 94.9 FM, now WSLC-FM). Channel 7 has been a CBS affiliate since its sign-on, owing to WDBJ radio's longtime affiliation with the CBS Radio Network. WDBJ-TV was the third television station to sign-on from Roanoke, after NBC affiliate WSLS-TV (channel 10) and WROV-TV (channel 27, frequency later occupied by WFXR), which operated as an independent station from February to July 1953. Before channel 7 signed on, CBS programming had been carried part-time on Lynchburg-based WLVA-TV (channel 13, now WSET-TV). During the late 1950s, WDBJ was also briefly affiliated with the NTA Film Network. For close to two years, the station's construction permit was heavily contested between Times-World and the owners of WROV-TV, who relinquished their UHF license (the station went dark in July 1953) in order to battle for channel 7. The two-way contest virtually ended in January 1955, when the WROV group relinquished their application and sold their television assets to WDBJ. The Times-World Corp. would be awarded the channel 7 construction permit two months later. Channel 7, along with its radio sisters, originally operated from studio facilities located in the Mountain Trust Bank Building in downtown Roanoke. Its transmitter was located temporarily on Mill Mountain; the station originally planned to transmit its signal from Poor Mountain, but was not able to do so due to concerns regarding interference with the signal of WSPA-TV in Spartanburg, South Carolina, whose broadcasting facilities were under construction at the time. In 1956, WDBJ radio and television moved their operations to the Times-World Building; the television station also relocated its transmitter to Poor Mountain. Due to its affiliation with the Times and Virginia's second-oldest radio station (AM 960 had signed on in 1924), WDBJ-TV overtook WSLS-TV as the area's highest-rated station
