 Liggett changed the station's call sign to WFMK, and initially programmed a mix of Adult Contemporary music as "Stereo Island, WFMK 99" during the day (using the "Stereo Island" approach pioneered at WKNR-FM in Detroit), and Album Oriented Rock overnight.The AOR portion of the format was dropped in the mid-1970s, and the Adult Contemporary format expanded to 24 hours a day, under the moniker "Easy Rockin' FM 99".Over the years WFMK's adult contemporary format has evolved to the point that the station's current slogan is "A Variety From the '80s to Now."
