South Central Kentucky's original Fox affiliate was WNKY from 1992 until 2001 when that station switched to NBC. From that point until the launch of WBKO-DT2 on September 5, 2006, WZTV in Nashville, Tennessee served as Bowling Green's default affiliate on cable and over-the-air (in some locations). As a result of the addition of WBKO-DT2 and CBS on WNKY-DT2, Bowling Green now offers every major broadcast network except MyNetworkTV and Ion Television. On December 8, 2008 at 1:15 in the morning, WBKO shut down its analog signal in a flash-cut procedure. This allowed the station to begin the process of installing a new digital antenna and other equipment.
Originally, WBKO digital signal was scheduled to move to VHF channel 13 on or immediately after December 22. However, due to inclement weather and the holiday season, the construction took longer than anticipated with eight more days of construction resuming on January 3, 2009.  Due to the installation of the equipment at the transmitter site, the digital signal (on UHF channel 33) was off-the-air during daytime hours so that installation work could be completed.  Until the completion of the over-the-air transition, WBKO and this Fox subchannel were seen non-stop on several area cable systems.
On October 21, 2007, WBKO-DT2 began airing a thirty-minute prime time newscast on weeknights known as WBKO Fox News at 9. Sarah Goebel originally anchored the show until early-2008 when she was promoted to WBKO's main weeknight broadcasts. After this, Daniel Kemp was the news anchor until early-June when he moved to the weekend newscasts on the main channel. Julie Talley would host the prime time broadcast for a short time in mid-2008 after which reporter and internet producer Sam Provenzano anchored the show until its cancellation. WBKO Fox News at 9 stopped airing on November 28, 2008 as a result of financial issues. WBKO-DT2 continues to replay MidDay Live tapped delayed weekdays at noon. The broadcast features news anchor Hayley Harmon and Weather Director Chris Allen.
