We watch almost no broadcast TV, other than an occasional show on PBS or Packer football game. Our girls (9 & 11) usually watch an episode or two on Netflix every day and get a limited amount of "fun" screen time on the various other devices around the house. (Homework done on the computer doesn't count.)
During the summer, they end up with very little screen time. During the winter, they can sometimes end up with several hours in a day, particularly on days with no school when I have to work. In addition, they usually can have more screen time if it's something educational rather than mindless fluff.
