This doesn't mean that they aren't watching anything, but that they use the Internet and devices instead of a traditional TV and cable or satellite plan. I like what one person said about how it allows her to control the media she consumes and not get sucked into time-wasting shows.
This is exactly what I want for my family as we return to the States. The main reason that I currently use DVDs and YouTube with my son is because I don't want him watching commercials. I also want the program and its timing to be our choice, not someone else's. I've written about my TV worries before, but moving to the U.S. makes it a whole new ball game.
