Sep 17, 2012 - An interesting entry in James Cridland's blog gives some insight into radio's future. Basically, reason #85, the Internet won't replace radio broadcasting any time soon, is strictly an economic one. Now this is the U.K. of course, but the same laws of physics apply on this side. A spectrum crunch is coming our way and the end result will be more expensive mobile phone access with poorer service.
Don't get me wrong -- I see the need in and the value of streaming media. While streaming will continue to see more and more use, I don't see over-the-air radio going away any time soon, if at all. I foresee the RadioDNS model working in the long run.
By the way, if you really like to crunch numbers, read down to the comments in Cridland's blog -- see "Why the mobile Internet won't replace DAB radio broadcasting any time soon, reason number 86."
