up in the Spring 2007 period, while KBIG-FM saw a dip. Despite having been a rhythmic-based radio station, KBIG-FM was a loyal affiliate of Casey Kasem's weekly countdown show for hot AC stations, American Top 20, which aired Sunday mornings. Former KBIG morning drive personality Charlie Tuna was Kasem's regular substitute host. KBIG had been the flagship station for Casey's adult contemporary countdown since it launched in 1992 until the station flipped back to hot AC in 2007. In February 2007, KBIG-FM added Delilah back to its lineup. The news of having the program air on the station generated much talk because her show is geared toward a mainstream AC audience and seemed out of place on the rhythmic-oriented station. However, after adding Delilah, KBIG-FM began adding more mainstream AC content to its playlist. "104.3 MYfm" During the first week of September 2007, there was talk about KBIG-FM flipping formats as several domain names had been registered that hinted at such a change. On September 17, Charlie Tuna confirmed a change was coming when he announced that he was out as morning host after 7 years on his website, but would continue to work within Clear Channel's Los Angeles cluster.

(KYSR would switch to alternative rock a few days later on September 20.) The first two songs on "MYfm" were "Hey There Delilah" by the Plain White T's and "Livin' On A Prayer" by Bon Jovi. (KBIG-FM's former Rhythmic AC format would move to their HD2 channel and sister station KHHT (now urban contemporary-formatted KRRL); the HD2 is now airing an LGBTQ-centric dance music format branded as "Pride Radio".) Denes described KBIG-FM's new approach as "Contemporary Adult Hits". In an interview with R&R Clear Channel Los Angeles vice president of programming Michael Martin said, "With today’s consumer wanting to custom tailor everything to their liking, the name MY is a perfect brand for radio. This is a station designed by the listeners to play music they tell us they want to hear. How do we know what they want to hear? Extensive, market research and continual-weekly music information to keep the station familiar, fun and family friendly." Martin continued, "MY
