Sacrifice? Broadcasters? PPPPBBBBBBBBBT!
Let's see....in a medium size market such as Austin, one broadcaster is going to take a valuable FM frequency and convert it to digital, thereby disenfranchising 99.95% of the listening audience. And if it's CC, all they'll have on those nine channels are nine Internet-ish streams that one can hear anywhere, since no one is going to waste LOCAL talent when no one, repeat on one will hear.
Naw, as interesting as the idea is, broadcasters everywhere are busy milking the last few ounces of profit out of the analog stone to invest, yes invest properly in digital. Especially when it's the mess forced upon the business by Ibiquity and it's fully-owned subsidiary, the FCC.
Like my friend said .... we'll have digital, but it won't be this digital.
