I wondered this question myself, so I thought others might be interested in seeing the answer that I found as to why the switch from analog to digital. Here ya go!
DTV technology is more flexible and efficient than the current analog system, that we have been using. The switch to digital allows television stations and opportunity to offer crystal-clear pictures and sound as well as more channels and programming.
Apparently there was an act passed in 2005 called the The Deficit Reduction Act which requires full-power television stations to stop broadcasting in analog channels by February 17, 2009 and begin broadcasting exclusively in a digital format.
What this does is free up parts of the airwaves. This helps TV stations to improve their services.
