Social networks and online game traffic top email, web portals

According to Businessweek, U.S. Internet users are spending more of their online time with social networks and games, and less with email and traditional web portals like Yahoo! and MSN, based on a recent Nielsen report.

In June, web surfers devoted 23 percent of their time online to social networking sites, up from 16 percent a year earlier, largely due to the growth of Facebook, according to the report. Online games, spurred by applications such as Zynga’s FarmVille, rose to 10 percent, taking the No. 2 position previously held by email.
