Comparisons?

Where’s a good site I can find that say, if I type in HDTV, it’ll tell me percentages of people who own HDTV’s in USA for example.

i don’t think there IS a single site that would have comparative info on various things like that.

i think you might be able to find a site that would give you info on HDTV. a different site that would tell you about cell phones, a different site that would tell you about people using VoIP. but i could be wrong.
