After Clear Channel acquired WPYX in 2000, their trademarked "KISS FM" CHR format was adopted on May 26, 2000 after a day of stunting, with the WKKF calls following soon after. WXCR personality Steve Scott was the only one to make the transition from classic rock to CHR as Jeff Mrozek adopted the afternoon drive spot at former sister station WQBK-FM earlier that year. Since its launch, WKKF has been a largely successful station going after heritage CHR WFLY with a more rhythmic, younger-leaning format. This approach has allowed it to hold its own against WFLY, a station which had not seen competition for a decade prior to WKKF's launch, and WAJZ, a Rhythmic (since 2005) who happens to be WFLY's sister station.
