The document discusses teens and advertising. It notes that advertisers spend over $15 billion to reach the 32 million teens in the US, who have $233 billion in income and influence over $600 billion in spending. Advertising works on teens by capturing their attention through repetition and appealing to their motivations to be cool, fun, popular and feel good. However, today's teens are more networked, interactive and focused on self-expression through social media than older generations. This means brands need to offer more user-designed and personalized experiences to appeal to teens.
