Well, after announcements, commercials, and delays which generated more announcements and commercials, broadcast TV is finally being dragged into the 21st century at 12:30 pm today. That's when channels all across the country shut off their analog signals and just broadcast digitally. If you're still one of the multitudes who use an antenna and did not prepare for the transition by buying a converter -- and, according to Nielsen, 2.8 million people still aren't ready -- you'd better run out and get one now or else you're just going to see snow.

For those of you who have already made the transition, you'll notice that there are some extra channels on your TV, maybe with names like 2.1 or 2-1 or 12.13 or 13-12 or whatever. Some channels have taken advantage of the extra bandwidth DTV allows by broadcasting extra channels of specialized content. But are they worth watching? At this point, not really.
