you nothing? If this website is accurate, the broadcast will still be over the air but a digital signal instead of an analog one? Heres the link to what I looked at today, I had a conversation with my brother and mother earlier today about it so I went to this site to check into it. I told them that I was pretty sure they wouldn't want to take away our ability to see their corporate friends commercials and the government controlled news entertainment channels.
If it turns out it will cost a penny, I wont pay it, I will just watch dvds and ignore the rest.
