Mobile

Though Facebook released its first iPhone app on July 10, 2008, the social network only really decided to embrace mobile over the past couple of years.

For too long, Facebook insisted it didn't need a presence beyond the Web. Slowly, it added apps for the iPad and smartphones and tablets running Google's (GOOG) Android mobile software. It even built several standalone apps, including the popular Messenger, less popular Home, Camera and Poke apps and and just-released Paper app.

What started as a modest way to check your feed and acknowledge friend requests has morphed into a way to connect to the world and share your life on the fly. You can instantly share photos and videos from wherever you're at, get the address from an event invite, chat with a friend, or share your location.

For many, mobile has become the de facto way of using Facebook. For the first time last quarter, Facebook generated more revenue from mobile ads than desktop ads.
