A friend of mine has two kids <= 5 years old who have grown up using Netflix. They saw cable TV for the first time when visiting a relative for the holidays, and he was worried that they seemed to have a lot of trouble distinguishing ads from content. I suppose it's a good thing to teach. How else are kids supposed to know? How do kids who grew up with broadcast and cable ads learn to tell them apart?
