The station signed on the air on September 10, 1983, as an
independent station and aired an
analog signal on UHF channel 23. The station was originally owned by Cape Girardeau Family Television, Ltd., in turn 51 percent owned by Media Central of
Chattanooga, Tennessee. Prior to the station's launch, two independent stations were broadcast in southern Illinois, and a prior attempt had been made at an independent in Paducah, but this was the first independent station to cover all of the market, which was the reason Media Central had been attracted to the area. Media Central filed for bankruptcy in 1987, and attempted to sell its properties to another television station owner. On September 7, 1987, KBSI joined the Fox network despite declining to carry the network the previous year, partly because of the Media Central bankruptcy. Media Central continued to own the station until a bankruptcy judge approved its acquisition by Engles Communications, owned by David Engles, a former Warner Bros. and NBC radio executive. Under Engles, KBSI aired the first season of
NYPD Blue when ABC affiliate
WSIL-TV refused to air the show. Engles then sold the station to Max Television (later
Max Media Properties) in 1995. In 1998,
Sinclair Broadcast Group acquired most of the Max Media Properties stations, including KBSI; it owned KBSI and later WDKA in Paducah until both were sold to Community News Media for $28 million in a transaction that closed in 2021. On July 22, 2025, Sinclair announced that it had repurchased the non-license assets of KBSI and WDKA, with an option to reacquire the stations' broadcast licenses. On September 22, 2025, it was announced that
Rincon Broadcasting Group would be buying the KBSI and WDKA licenses along with the other stations owned by Standard Media for $50 million; the sale was completed on February 27, 2026. ==Newscasts==
