On October 9, 1986, WDRB-TV became an affiliate of the Fox network and became known as "Fox 41" in late 1989. WDRB-TV became one of two Fox affiliates serving the Louisville market in 1990, when Campbellsville-based WGRB (channel 34, later CW affiliate WBKI-TV) affiliated with the network. Channel 34 served the southern portions of the market before it moved its transmitter farther north to service more of the market; WDRB became the sole Fox station in Louisville when WGRB became a WB affiliate in 1997.
