One important point is that the data is for households, and the US have (i) bigger households than most other industrialized countries (ii) definately have more tvs per household than any other country. So these things might skew the numbers in favor of the US. But we definately watch a lot of TV. I think one reason is that the US is probably the biggest homogenous TV market (in temrs of advertising dollars) which allows marketing people to spend a lot of money to craft advertisements and TV shows more specifically to the audience and make them irresistable to us. You definately do not want to be in the cross hairs of marketing people. But I would advise all my fellow americans to do what I did .... do not have a TV or if you have one do not connect it to a TV signal (connecting it to a bluray player or netflix online is fine). You'd be amazed of all the free time you get to waste on the net. Also you get to be that pretentious a-hole that mentions he does not own a TV whereever someone mentions a tv show they like so much. It's a win-win situation.
