K.M., you expressed your doubt that "CBS would have gone to a satellite-delivered format in Los Angeles." Until 1993, I never would have thought that any radio station in the nation's second largest media market would switch to satellite programming...and then Shamrock bought KLAC from Malrite and changed the format from country to adult standards, using Transtar's satellite-fed "AM Only" programming. I was outraged that a Los Angeles station would choose to have no local news and no local DJs. And newsman Dean Sander was fired after 31 years! Eventually he was brought back to do an occasional one-minute travel feature. Shamrock's chairman was Roy E. Disney, son of Roy O. Disney and nephew of Walt Disney, and he hated country music. Shamrock also bought KZLA and there were rumors that Roy wanted to change formats at that station too.
Perhaps CBS did not want to be the first company to run a satellite format on a Los Angeles station...but in 2005 they installed an automated format, "Jack-FM," on the aforementioned 93.1 FM. No local news, no sports, no weather, no DJs---automation isn't much different from a satellite feed, is it? But CBS did it and the format has lasted for almost ten years so far.
