There isn't enough bandwidth to convert every terrestrial listener to an internet stream. Damn straight the data to do that isn't going to be free. Wide swaths of the country exist where reliable 3g/4g is still a dream. That includes a lot of the state of Kentucky. We seriously don't want OTA to completely go away. Cell service can be impeded, internet can be shut down by hackers or by government, and depending what eventually happens with net neutrality, you may only be allowed to stream what Comcast or AT&T has deals with. The guy who came to paint my office awhile back had a radio tuned to the classic rock station, not an iPod dock with 8 hours of mp3s or a stream of obscure indie music. The "I won't listen even for five minutes to anything other than a custom stream" is seriously overrepresented on forums like these. AM will never come to prominence again but will remain a home for ethnic, specialty, religious and maybe even TIS-type services.
