When it comes to shopping online, teenage users are a contradiction: Most teens don't have their own credit card, yet they love to shop online. (Which simply proves they have access to their parents' card). About 80 percent of online teens age 12-17 visit retail sites, according to ComScore. This represents an audience of between 12 to 15 million teen shoppers. For example, eBay saw 6.4 million teen users in April 2006, while Amazon saw 3.5 million and Apple saw 3 million. (In Apple's case, iTunes was surely the draw.)
Another paradox about teens online, or perhaps it's best described as a myth: Teens are not the super tech-savvy users they are popularly thought to be. According to popular conception, teens are far more adept at Internet use than adult users.
