The station first signed on the air on March 27, 1950 as a primary CBS affiliate. Originally broadcasting on VHF channel 9, it was the second television station to sign on in the Louisville market and the state of Kentucky (after NBC affiliate WAVE, which started in November 1948). It moved to VHF channel 11 on February 7, 1953, one of several channel shifts resulting from the Federal Communications Commission's 1952 Sixth Report and Order. Under the same decree, WAVE-TV relocated from channel 5 to channel 3.
This logo resembles what NBC affiliate WPXI in Pittsburgh would later use since 1987.
WHAS-TV switched affiliations with WLKY on September 8, 1990, becoming an ABC affiliate. At the time of the switch, ABC was the second-most-watched network in the country (after NBC), and the network was concerned with WLKY's ratings; CBS was at a distant third during the midway-point of president Laurence Tisch's helming of the network.

The "11" was taken out of its circle, and placed in a box.

The serifs were removed, and now the "11" resembles that of KCBD since 1994 and sister station WXIA-TV since 2019.
