American youth have personal television sets, laptops, iPods and cell phones all at their disposal. They spend more time with media than any single activity other than sleeping. As of 2008, the average American ages 8 to 18 reported more than 6 hours of daily media use. The growing phenomenon of "media multitasking"—using several forms of media at the same time—multiplies that figure to 8.5 hours of media exposure daily. Media exposure begins early, typically increases until children begin school, then climbs to a peak of almost 8 hours daily among 11 and 12-year-old children. Media exposure is positively related to risk-taking behaviors and is negatively related to personal adjustment and school performance.
