1979[]
KSD AM radio was sold in 1979, and KSD-TV modified its callsign to the current KSDK on July 10, 1979, due to an FCC regulation in place at the time that stated that TV and radio stations in the same market, but different ownership had to use different call signs. The station took on a new logo to go with the callsign change.

Simplified version of the previous logo; it now is bi-sected; previously, it had five stripes going through it. Pulitzer traded channel 5 to Multimedia, Inc. for WYFF and WXII-TV in 1983, though the takeover of WYFF would not be completed until January 1985 as they had to sell off WLNE-TV in Providence in order to comply with FCC ownership limits of the time that limited the number of stations one company can own to twelve; in the interim, Pulitzer took over the operations of WYFF through a time brokerage agreement with Multimedia.
