What would be the purpose for terrestrial radio to emulate the failed pay satellite radio philosophy. People don't want to pay for radio. I'm sure XM & Sirius wish this wasn't so but neither one is all that successful.
I'm sure there are people who would pay to use your HD-2 channels, just like they pay for SCA channels. Why not? Besides, who said the subscription would have to be for an audio service? I can think of all kinds of data streams that people might pay for.
Bottom line, all those new "free" channels may very well not end up being free for very long, or even something the public is invited to listen to. If I had a 100kW transmitter running HD and someone wanted to pay me more for one of my secondary channels than I could make by actually programming it with music and selling spots, I'd give the idea serious consideration. I'm sure that anyone who is responsible for the finances of a radio station would too. In the business world, the financial people really don’t care about radio programming and its content, they care about maximizing their investment. That's just the way things are.
You may have free and unique programming on most HD stations for now, but I wouldn't get too used to the idea. There is no guaranty that it will always be that way.
