Gen Y Americans (those aged between 18 and 26) spend 12.2 hours online every week, 28% longer than 27-40-year-old Gen Xers and almost twice as long as 51-61-year-old Older Boomers. Gen Yers are also much more likely to engage in social computing activities while online, Forrester Research claims. For example, they are 50% more likely than Gen Xers to send instant messages, twice as likely to read blogs, and three times as likely to use social networking sites like MySpace.
