The Facebook Platform was launched in 2007, allowing third-party developers to create applications that accessed Facebook data. Originally called "Canvas", it enabled apps like games to exist within Facebook. Over time, Facebook expanded the platform by launching Facebook Connect in 2008, allowing external websites to connect to Facebook accounts, and the Like button in 2010. The Open Graph launched in 2011 let developers more deeply integrate apps. These changes helped grow the platform to quarter of a billion monthly active users playing games and billions in annual revenue for developers.
