Playoff baseball has been a boon for our local Sports Radio stations.

For the third time in a row, KNBR leads the San Francisco market in the Arbitron ratings. The Game posted it’s highest ratings ever, moving into the top 25 in the market. Even KNBR’s other station had a good month, snapping out of a low ratings funk.

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

San Francisco












KNBR-AM 5.2 958,300 5.7 974,800 6.1 990,900 Cumulus

For those who are more visually oriented, here are the ratings in graphical form for the last year:

I was disappointed last month that the Game fell back a bit after posting very good numbers in August. This month there was no such disappointment.

While they didn’t really close the gap much in terms of ratings with KNBR, the Game did manage to keep pace. In addition they grew their audience size quite a bit, adding nearly 200k more listeners during the period. I might have been a little quick in writing them off after the bump in the road last month, time will tell.

What might be most encouraging was that this wasn’t necessarily driven by a deep playoff run from the A’s. After reaching the playoffs for the first time since 2006 the A’s were bounced out in the ALDS in five games by the eventual AL Champion Tigers.

Over at KNBR, 680 rode the second Giants Championship in three years to their third straight monthly ratings crown. In addition, this is the third straight monthly gain in both ratings and audience. Things have gotten off to a great start this fall at the “Sports Leader” with the Giants; now it will be interesting to see if they can have a stronger winter than they did last year.

Things at KNBR 1050 don’t look nearly as good. This time last year was in the middle of the “Damon Bruce Surge” that has proven to have not been sustainable. The year-over-year numbers are really ugly, but on the bright side the 0.8 rating is the highest in ten months and the 347,000 listeners is the highest since the November last year.

Here are the YOY Changes:

  October 11 – October 12 Ratings October 11 – October 12 Listeners
KNBR 43% 30%
KNBR 1050 -50% -18%
KGMZ (the Game) 43% 58%


October was a good month for Sports Radio. Both KNBR and The Game posted record ratings highs since I started tracking the ratings monthly. Both had great year-over-year growth in ratings and audience size. Everything seems to be moving in the correct direction.

However, winter is coming. If last year was any indication this might be the high point of the year as baseball packs it in until the Spring. It will be interesting to see if the stations can maintain their audiences into the off-season better than last year.
