It became clear 25 years ago that radio was aiming for the captive audience of commuters stuck in their cars or buses.

Prior to that, I would listen to the radio while working on stuff, looking forward to the late night Friday and Saturday harder rock and b-sides.

Once the private stations sold out to large conglomerates (which may have been inevitable anyway), it all went down hill.

It wasn't video that killed the radio star, it was the mp3.

NPR does not have to worry about pedestrian things like ratings.
