Drew Angerer/Getty Images(CNN) - U.S. teens spend an average of more than seven hours per day on screen media for entertainment, and tweens spend nearly five hours, a new report finds -- and that doesn't include time spent using screens for school and homework. Nearly 62% spend more than four hours a day on screen media and 29% use screens more than eight hours a day, according to a report by Common Sense Media, a nonprofit organization that helps kids, parents and schools navigate media. They tracked changes in youth media behaviors, comparing current results to those found in the first wave of the study in 2015. The screen media time figures don't mean youth were exclusively using screen media for that period. It addressed all types of media, including reading books in print, using social media, watching online videos and playing mobile games.
