Engagement with mobile social networks surpasses that of Facebook and MySpace.

SEATTLE—April 21, 2010—The Mobile Internet may be just as reliant on social networks as it is on the mobile data network itself. Ground Truth™, the mobile measurement firm that provides precise, timely and actionable mobile intelligence, today revealed that social networking activity comprises more than half of the time spent on the Mobile Internet. Ground Truth also reported that users of mobile-specific social networks are more engaged than users of PC-based social networks, such as Facebook and MySpace, on mobile.

“While the popularity of mobile social networking is widely believed, this is the first time we have been able to truly quantify just how much the category is driving adoption of the Mobile Internet with actual usage metrics,” said Evan Neufeld, vice president of marketing, Ground Truth. “The disparity of time spent between social networking and the next category, portals, which account for 59.83 and13.65 percent of time spent respectively, is a vivid illustration of the impact social networking has on Mobile Internet traffic in a given week.”

“Facebook and MySpace may be the most addictive pastimes on the PC, but sites like MocoSpace and AirG command more attention on mobile phones. For example, each MocoSpace user spent in excess of an hour more on the site than did the average Facebook visitor during the week,” observed Neufeld. “This data points to the fact that there is a whole universe of media properties advertisers need to consider that have to date been largely ignored. It also demonstrates that traditional media companies that are not focused on the Mobile Internet—both browser- and application-based usage—risk losing market share to leaner, more mobile focused companies.”
