Previously, strong mobile views were not originally considered as a positive by Facebook as the company was "under monetized" in the mobile space. But over the last year, Facebook has changed that, adding more ad impressions that could be seen on the social network's mobile app and through a smartphone browser. And there could be more Facebook coming to mobile devices.
Earlier this month, we told you that Facebook is thinking about launching a Flipboard-like, magazine style news reader. Also, there is talk that Facebook is going to start its own mobile ad network that would put Facebook generated ad impressions on free apps. If this comes to fruition, Facebook would benefit, app developers would benefit, and the rest of us will have more ads to sift through.
