Conjur has it right.
There are a lot of myths and misconceptions in this thread.
There is no federal mandate for HDTV. Only a mandate to switch to digital broadcasting.
If a map was made of the US showing areas with BB access in blue, and areas with no BB access in red, most of the map would be red.
My 2 cents: The way to make this happen is to deregulate, lower taxes on communications companies and encourage competition rather than government sponsered utility monopolies. The WRONG way to go about it is to socialize it by offering public funds to build it. There is no reason a company should be forced or bribed to offer unprofitable services. Unless, of course, you want a broadband service that runs like Amtrack.
