Children cannot be cocooned in this way. They watch more adult television than television produced for them. This doesn't mean that advertising to children is ineffective, just that it is not the all-persuasive controlling influence that its critics assume it to be. I would go further than this. I believe exposure of children to advertising, provided that this is controlled and such material is responsibly produced, is a good thing.
Children have rights to information and education.
They are given pocket money and, under parental influence, are encouraged to make choices and learn how the world operates. Understanding how the commercial world works, and managing this process, is an important part of education and not one of which adults should either be frightened or try to ignore. First within those markets in which children are legitimately involved there will be less choice, less competition, less innovation and higher prices. Advertising is no more or less than a tool of competition and in all the markets in which it operates it encourages competition, innovation, lower prices and consumer choice. There is no evidence that in children's markets it behaves in a different way.
