About WBKO ABC13Professional Telecasting, adopted the WBKO (an acronym for Bowling Green, Kentucky's Own) call sign and instituted color telecasting for local in-studio programming and newscasts in 1971. By this time, the station had moved to studios on East 10th Street in downtown Bowling Green. In 1976, a local group known as Bluegrass Media bought WBKO from Professional Telecasting. It remained in Bluegrass's hands until 1983 when broadcaster A. Richard Benedek took over. Under Benedek's management in 1985, WBKO built its present studios on Russellville Road.
By October 7, 2001, an agreement between this station and the area's cable provider allowed WBKO to launch cable-exclusive WB affiliate, "WBWG", through The WB 100+ Station Group because the Bowling Green market had a rank of 183. Since it was a cable-exclusive outlet, the "WBWG" call sign was not officially recognized by the Federal Communications Commission (FCC). WBKO provided sales and promotional opportunities to "WBWG". By September 3, 2002, the station's WB+ cable channel was also identified as WB12.
