WABG-TV's first broadcast was on October 20, 1959, on VHF channel 6. Originally it was a CBS affiliate, with a secondary affiliation with ABC owing to WABG radio (960 AM)'s affiliation with ABC Radio. In 1966, the station built a 1,200-foot (366 m) tower near Inverness and increased its effective radiated power to 100,000 watts. Following its completion in October 1966, WABG dropped CBS to become a full-time ABC affiliate in November 1966. Until then, the only areas of the state to receive a sole ABC affiliate were the northwest (from Memphis' WHBQ-TV) and the Gulf Coast (from WVUE in New Orleans). Until future sister station WXVT signed on in 1980, WJTV in Jackson served as the default CBS affiliate for the southern counties in the Delta area, while WREG-TV in Memphis served the northern half of the market, Mississippi cities like Kosciusko received WABG-TV on their analog television set as their default ABC station from 1970 to 2009, as WAPT in Jackson did not have a strong signal on analog television in the Kosciusko area. On March 12, 1986, the studios of WABG were damaged by a fire triggered by an electrical short circuit after the station signed off the air for the night. With no injuries being reported, the station was forced to relocate its transmission signal.List all of the call signs mentioned in the paragraph
