It's a fact that it takes a lot gain a "call to action" threshold with folks over 50. So, why would an advertiser want to spend $100 to motivate you and me while it takes only $50 to get the same results reaching the 30 somethings? It onlt dollars and sense. Sure, there a products and services geared to the greybeards (cemetery plots, cruise ships, Lipitor, etc.) but this is a highly targeted market where other advertising forms may be more effective (direct mail).
Like you, I would like to hear a wider variety of music and information but as has been stated here and other message boards, there are many pressures being brought to bare on the market that renders we older listeners "out". It would be great if it were different but it's not and so we need to migrate to such delivery systems like the internet or satellite. Even XM is starting to focus more and more on the key deomgraphics and dropping "stations" like the Great American Songbook.
