The question I have with this is why did the government have to get involved? In almost all other tech transitions that I know of (in my very limited experience) was industry driven, not government regulated.

The freeing up of bandwidth for emergency use puzzles me. All the tv stations in my area will still be broadcasting on the same channels, but we get several subchannels... whoopee... how does this free up bandwidth if they are still broadcasting on the same channels? (I am assuming that each channel corresponds to a certain bandwidth signal) Just confused I suppose.
