"The
average American child age 8 or older
spends more than seven hours a day with screen
media, watching TV, using the computer, playing
video games, and using hand-held devices.
Even much younger children, age 2-8,
spend nearly two hours a day with screen
media. And through virtually all these media,
children are exposed to advertising."
