I don't know if it's my imagination but I've noticed this with FM radio too. Sometimes I'll turn on the radio in the car because there's a local station that plays music I like, but it's become unlistenable because the ad:music ratio is about 50% now. And the ads seem to be mostly for things boomers might buy (like hearing aids, luxury cars, and blood pressure medicine), because of course everybody younger never listens to the radio.
FM radio is dead; it just doesn't know it yet.
