Yes, this is a beauty contest, (advertisers only care about demos,) but some trends: KNBR really does DEPEND on the Giants...KGO, once the king of the hill, is stagnant now at best, (up, mildly), and KCBS is the big winner, (again) in the February ratings.
KGO Note: It's up 30% in 25-54 since November, but still at a miserable 16th. #1 in that demo is KQED, followed by KBRG and the KCBS AM and FM simulcast.
The full breakdown is here.
