Back in Janaury, it was surprising to see All News KCBS leading the ratings in San Francisco for listeners 6+. The question then was: Had KCBS dethroned KGO-AM? Or was it a fluke? Six months later, the trend has become clear, with KCBS on top and KGO 810 slipping to No. 4. CBS Radio’s decision to put the all-news station on FM is paying off.

Here’s the usual disclaimer: Advertisers don’t use these numbers when buying air time. They use ratings for particular demographics.
