Most mass-market TV shows and movies are such that you can tune out a good 25% of the time and still follow them just fine. Some of the worse ones aren't even as demanding as that.
Also, people want to do something with their hands while watching things, and not everyone knits or (especially, these day) smokes, or pops popcorn before every movie they watch at home. Bet a huge percentage does something else while watching TV/movies. Sudoku books, whatever.
