Assuming this isn't a rhetorical question, I'll answer it. The old system - designed in the 1930's, ratified in 1940, is inefficient. It requires a whole lot of precious limited bandwidth to broadcast a single format signal. DTV not only saves bandwidth, it can carry many different formats. It's also a much clearer picture, not susceptible to the snow and ghost that the 1940 system was.
An analogy: In 1940 we needed a big bus to deliver one channel. With DTV, we can use a minibus, and each one can carry many different channels. And you can actually see out the windows on the newer minibus. You may eventually get coverage in the outlying areas. The FCC has already approved many requests for signal "repeaters" which are meant to restore coverage to pre-DTV areas (no permits are being issued to *extend* pre-DTV coverage). Assuming these repeaters get cheap enough (and they should be soon) we'll probably see them popping up all over the place.
