Milliennials, those ages 18-33, remain more likely to access the internet wirelessly with a laptop or mobile phone. In addition, they still clearly surpass their elders online when it comes to: Use of social networking sites
Use of instant messaging
Using online classifieds
Listening to music
Playing online games
Reading blogs
Participating in virtual worlds
However, internet users in Gen X (those ages 34-45) and older cohorts are more likely than Millennials to engage in several online activities, including visiting government websites and getting financial information online.
Teens are by far the most likely to play online games: 78% play games online, the most popular activity for that age group.
