According to a new study released this week, one-third of American teens own an iPod, up from only 1 percent in 2003. The Harrison Group’s 2006 Teen Trends study surveyed 1,000 Americans aged 13 to 18 on their thoughts and habits. The study also found that 75 percent of teens spend two or three hours a day downloading or listening to music online, with half of those teens saying that downloading music for free is illegal. The study also reported that more than half own Sony’s PlayStation 2, and one-third own an original Microsoft Xbox. An estimated 68 percent of teens have created pages on social networks like MySpace, Xanga or Facebook.
