The Facebook Platform is an umbrella term used to describe the set of services, tools, and products provided by the social networking service Facebook for third-party developers to create their own applications and services that access data in Facebook. It was launched in 2010. The platform offers a set of programming interfaces and tools which enable developers to integrate with the open “social graph” of personal relations and other things like songs, places, and Facebook pages. Applications on facebook.com, external websites, and devices are all allowed to access the graph.
