Actually, I am a programmer and a pretty good one. I am in favor of
anything that extends the life of AM radio or terrestrial radio in
general.
The consumer, too, should be in favor of this as commercial-based radio
is
free, and every other option has ongoing delivery charges.



So, digital modulation is an attempt to extend the life of commericial
radio. Will digital modulation always remain free?

Yes. The model is free for listener, paid by advertiser. There are nearly a
billion analog radios out there, so there is no effective way to do pay
radio, and the entire licensing system would have to change, something I
doubt the FCC and the folks on the Hill would stand for.
