Like grimes says HDTV is the law now in North America. I read somewhere that the government wants to free up the exsisting SD frequencies for other purposes like emergency response sectors. The feds wanted to pull the plug on analog when 85 percent of the country has HDTV. The original deadline was 2006 but only about 10 percent to 12 percent of households has gone HDTV as of a couple months ago. So now, the government is saying 2015.
But, these HDTV's are selling like mad! Yes - they are expensive but, they are taking over the showrooms here. Best Buy is a good example. The big screen, be it Rear projection or Plasma is front and center with the old SD CRT shoved in the corner. Actually, EDTV is pretty darn reasonable in price and 480 p ain't bad. A lot of sports fans are probably chucking their behemouth RP SD TVs for one of these as the price is about the same, <2000 bucks.
I was just thinking the other day, how when I first got into computers, Best Buy the whole center of the store was software. Now I think there are a couple (short) aisles turned sideways. The DVD as you say is dominant. The cool thing is, you can take these DVD's - put them in an upscaling DVD player and voila! You are watching a damn nice picture! So, there are people trying to help us take the plunge and not throw our money away. I love my new Panasonic 7UY plasma and you would have to pry it from my cold dead fingers. Can't stand to watch the 32" CRT upstairs any more. HDTV will take off big time in no more than 2 years! That is my prediction. GO VOOM!
