it is amazing that the people who are attempting to push this through assume that all of america can afford cable. i have some sad sad news for the FCC and the attempt to do away with analog broadcasting. that news is there are a shitload of poor people out there that can not afford foor and insurance and christmas for their familes, and they want to make you spend more money buy having to pay for digital service? kiss my ass is what i say. i hope the FCC dries up and blows away. they need to chase CBers running big fat linear amplifiers.
You do not have to have cable. The digital signals are sent over the air (OTA) just like the analog ones. For those without Digital tuners you can get two(2) $40 vouchers for conversion of OTA digital signals for use on non digital tvs from the govt(starting in 2008). You can use the same antennas in most cases. All TVs manufactured for sale in the US since 07 (? I think that was the year) had to have digital tuners.
