In the 20s and early 30s there was a radio station, IIRC, in Cincinnati broadcasting with 500,000 watts. People were picking it up with their fillings, on barb wire in Wyoming, and it went all the way to Australia. If we had the free market prevail, two or three of those would have dominated radio. I don't think that was a good thing. In fact government intervention ensured more broadcasters could get into the market.
HD is a improvement of the standard. People have had a 6 year notice with 1 extension. I'm sorry, I don't see the problem.
