Mark, I agree with you that today's seniors are much more active and have much more energy than seniors of 25 years ago. And, I agree w/ you that it does not matter to advertisers, so even when they are advised to "shift their perceptions", they don't pay much attention.The new MOR is classic rock if you're male; traditional AC if you're female. In ten or fifteen years, it will be "alternative".
A personal story, albeit not Bay Area-oriented: The owner of the station where I had my first professional full-time radio job was the same age that I am now. I remember thinking of him as a tired old man who often wanted to do the right thing but couldn't summon the energy to do so. And, sure, he had smoked, was down to one kidney, and seemed to feel deeply the stress of keeping his radio station going, even though it was quite profitable. I've never smoked, my health is good, and while I had a stressful profession post-radio, I learned how to manage that stress. I don't feel tired. I also don't drive a Lincoln Continental - the owner did - and that, right there, shows you how being in one's 60s has changed. Does that matter to advertisers? Not really. But they're the ones writing the checks, so telling them "you need to shift your perceptions" isn't likely to get very far, AARP The Magazine notwithstanding.
And, what this means is that the generations like the Boomers and Generation X, are dwindling in size, so there is less listenership, plus younger generations are moving to podcasts and individual playlists. I'm wondering if there are too many radio stations in the Bay Area for the dwindling listenership. They have to struggle for listeners and struggle for ad dollars. So, KYLD may not survive at all. JMO.
