Sorry DooWop, there are no illusions. You can stick your fingers in your ears and say "lalalalalalalala" all you want, or regale us with stories about selling your little specialty show on an underpowered AM in some podunk town, but the reality is, in the major markets, using PPM ratings technology, high cuming stations with younger demos are much easier to sell (and make much more money) than low cume stations targeting 55+. Radio stations are in the business to make money, not to provide "something for everyone." If there is an underserved audience that radio can reach they will do so....IF THEY CAN SELL IT! And this has been the case ever since radio was invented. It's a business first, and a content provider second.
Now that people have many different provider options, the prevailing wisdom is that "radio sucks." Radio is doing what it has always done...putting on formats that bring in the most listeners and can be sold at the highest dollar to the most clients. Radio will never be able to match your custom playlist on Pandora or your MP3 collection. That would be called "narrowcasting." Radio is in the business of "broadcasting." Talk (and 50's-60's oldies for that matter) doesn't reach enough listeners as they used to, and like network general interest entertainment, Big Band, EZ listening, and Smooth Jazz formats they will eventually go by the wayside to be replaced by ones that younger people prefer. It's just the circle of (radio) life.
It's just that older people sometimes get butthurt that it's their favorite music or talk format that falls out of fashion. At least there are internet options out there today...that didn't exist in past years.
