where was KGO in May 2011?
A better question might be, "How did KGO do in ages 25 to 49 in 2011 versus today?" It doesn't matter if a station is #1 if they have demographics that can't be sold. That was KGO's problem.
As I predicted, KGO's audience would level off; I didn't think for a moment that it would crash and burn. I expected a bit more from KKSF 910, but they have two problems: No advertising budget to reach find new listeners, and a bad nighttime signal that doesn't cover the market. The nighttime signal is a problem for people who like to set their radios to turn on in the morning, when most ralkradio listening takes place. If they can't set their radio for KKSF they'll set it for something else.
