What happens when the analog broadcasts of TV will end Feb 17 2009?

Currently, television in the U. S. is being broadcast in two methods; digital, and the original analog method. The analog method uses a large amount of the frequency spectrum, and sprays a great deal of radio frequency energy into the environment. The Federal Communications Commission has set a date for the analog transmission method to end. At that time, people with older televisions will have to buy a converter box to decode the digital transmissions. If you are on a cable system, the digital transmissions will be decoded by the cable system, so no additional decoder will be required.
