This subject was addressed in an earlier, now closed thread, so I'm reviving the topic to add some info about the station in the 1950s, which no one really addressed in the previous answers.
My dad, Dan Cotterman, was a disc jockey, announcer, and engineer at AM 1350 KCSB, which changed to KCKC, in San Bernardino, California in the late 1950s. The format at that time was definitely middle-of-the-road music. They played light jazz, pops and novelty instrumentals, and current pop singers' hits. By the very late 1950s they were playing more and more to rock-and-roll. My dad had no interest in that musical genre, so he moved on to KYNO in Fresno, California, then KHOT in Madera. Unfortunately (for him), rock-and-roll was here to stay, and most stations were embracing it. By the early 1960s he had changed careers.
