Nonsense. Go back to those stations that I listed that appeal to a young demographic, go to their webpages, check the DJ lineups (they have pictures) and tell me what "previous generation" is hogging the chair.
I'm not saying that EVERY radio station in the area is staffed with people over 55. But I'd say the majority are. Particularly on AM. Before the changes at KGO, almost the entire staff was in their 60s.
Sure you can pick three stations out of the entire market and find some young talent. But what about the rest? Is radio talent representative of the market audience? Does they relate to the changing demographic of the community, and are they reaching people sought by advertisers?
Even if you were right about AM (and we move the yarstick to 55 instead of 65), the age of the people on the air isn't what's keeping younger listeners away from that band.
And since you think "you can pick three stations out of the entire market and find some young talent", let's do the rest of the FMs:
KOIT: Jack Kulp is 58. Nobody else on the staff is near it. Sue Hall might...maybe...be 50.
KISS FM: Renel Lewis and Sylvia Chacon are market vets, but I doubt either of them is 55.
103.7: Don Bleu is over 60. Celeste Perry is another market vet, but like Renel and Sylvia, we're probably talking late 40s or early 50s.
Alice@97.3: Katie Mason's the only one who might be 40.
Star 101: Ryan Seacrest is the old man at 37.
KFOG: Dennis Constantine started in radio 46 years ago. So yeah, he has to be somewhere around 60. Dred Scott, too.
KBLX: Nobody's even close.
KSAN: Steven Seaweed is close to 55, if he's not there yet. Nobody else.
KITS: Is anyone even 30 yet?
Mix 106.5: Nada.
KBAY: Probably Sam Van Zandt (again, we're moving the line to 55 instead of 65), and maybe Dana Jang.
After that, we're into signal-challenged stations that don't break a 1 share. So we have Don Bleu and Dennis Constantine over 60, Jack Kulp at 58, Steven Seaweed at or near 55 and Dred Scott, Sam Van Zandt and Dana Jang somewhere in the neighborhood (again based on career timelines). That's a whopping seven guys at 5 radio stations out of 14 listed, with the rest of those staffs under 55. Far from a majority.
