My God! L.A. stations change talent like I change underwear...weekly. It seems like there's a change on at least one station every week. 8)
Remember the line to the WKRP theme song;
"Got tired of packing and unpacking, town to town, up and down the dial..."When was that - 30 years ago? I think it's always been this way, though these days its usually replacing one voice-tracked jock with another voice-tracked jock. In the 60s, most of the Top 40 jocks would come and go, often switching stations between KHJ, KRLA, KFWB, KDAY, etc. The only exceptions were the #1 drive time guys like Morgan and Steele, and even they switched stations once or twice a decade.
It's the same way in San Francisco, and everywhere, I'm sure.
You can find images of quite a few old radio record surveys on line - like the KEWB or KFWB Fabulous Forty. The personalities are all on the front cover. If you check any two a year apart, at least half of the jocks are different.
