"Young children are simply more easily persuadable than older children or adults. They are more trusting of advertising claims and appeal and more susceptible to commercial persuasion."

"As children grow older they gain the capability to distinguish between commercials and programs, to remember them for a long period times, and gradually come to recognize their persuasive intent."

"The 'effects' of television are not measurable only by counting heads in audience. What children get out of television is often quite different from what adults assume they get out of it."

"Children's desire to possess products they have seen on television is said to lead to "pester power", which means that children pester their parents or other adults to buy things for them."
