I am one of these Americans who does not own a TV set.
Allow me to rephrase: I don't have a cable box.
Housemate & I use our TV in the living room as a black panel to look at during conversations when it's not being used for Netflix & Mad Men DVDs.
I was raised in a house where we didn't get past channel 13 until I was in Middle School, so the TV watching habit is not ingrained in me. However, to most of you who are my age I'm sure the lack of cable is not groundbreaking. Our computers & smartphones are our windows on the world: I read multiple newspapers through Twitter, and watch TV shows and amusing videos on Hulu & YouTube.
Why pay $80 for a cable box when I can get all of that information for a far lower price? I live in the most exciting city in the country, I'm not going to sit in my house & watch the world through a box. I have only very occasionally wanted a TV: during the Egyptian Revolution (I watched it on Al Jazeera online) & to watch SToriBook Wedding (I got over it). Other than that, I don't really think about it.
What about the rest of you? Do you have cable? Do you think it's worth it? Anybody want to make any wild predictions about the future of television?
