Facebook has unexpectedly shut down its Creative Labs division, along with the apps it had previously created. Creative Labs was responsible for the Slingshot, Riff, and Rooms (read our first look at Rooms) apps, which were all created in-house by developers and designers working together.

The social network told, “Since their launches, we’ve incorporated elements of Slingshot, Riff and Rooms into the Facebook for iOS and Android apps. We haven’t updated these apps in some time and we’ve decided to officially end support by removing them from the App Store and Google Play.”

This suggests Facebook is concentrating its resources on improving its main app rather than creating a host of single-purpose apps. It could also stem from that fact that both Slingshot and Rooms were accused of being rip-offs of existing apps: Snapchat and Room, respectively.
