The latest Arbitron numbers were released yesterday afternoon, giving us a look at a year of ratings for the San Francisco market!

Here are the numbers updated through June (numbers on demographics or specific shows aren’t available to the general public):

San Francisco












KNBR-AM 4.8 842,900 5.1 929,600 4.7 889,400 Cumulus
KGMZ-FM 0.7 219,100 0.8 199,200 0.6 191,700 Entercom
KTCT-AM 0.5 198,100 0.5 212,600 0.6 300,500 Cumulus

*AQH is Average Quarter-Hour Share or the average share during any quarter-hour during the course of the day. Reach is the total number of people that tuned in during the course of the week.

For those who are more visually oriented, here are the ratings in graphical form since I started tracking this going back to June:

There weren’t any big changes the second month in a row. KNBR dropped a little bit going from first in San Francisco to forth. “The Game” too saw a slight ratings drop, but it managed to stay in the same general range of around a 0.7 rating, with around 200,000 listeners. KNBR 1050 saw a pretty big boost in the number of listeners but didn’t see a corresponding jump in their ratings.

Overall, there were no big movers in the ratings numbers.

The one thing I have been looking forward to is the ability to look at the year-over-year (YOY) changes, which give a comparison not biased by the seasonal swings that effect the Sports Talk Radio business.

Well here are the eagerly awaited YOY Changes:

June 11 – June12
KNBR -2.1%
KNBR 1050 16.7%
KGMZ (the Game) 16.7%


The 16.7 percent looks pretty impressive, but it is really small change from a small original base. Both “The Game” and KNBR 1050 grew from last year’s 0.5 ratings to 0.6, modest gains compared to the percent change numbers (but if you were at one of these stations and looking to spin it, there’s your talking point). KNBR is down slightly and because they started from a much higher base, the modest decrease is actually reflected in the percent change.

Hopefully, next month, we will see some more excitement in the ratings, but if all else fails, it will give me my first chance to look at year-over-year changes in the number of listeners.
