It's not just that, I think Clear Channel caused the true demise of radio. They own practically every radio station in the US and so there's been a massive homogenization of playlists across radio stations. College stations offer a small respite from the dreary same-ness that is corporate radio, but the stations near me don't have that much power so they only cover a small physical area and the more interesting shows aren't on during commute times.

For me, commercials are also a large issue--with TV I have a DVR and my browser has an ad-blocker, so I'm just not used to listening to commercials. They tend to start aggravating me after a very short time (10 seconds or so).

Those are the reasons I don't listen to the radio any more.
