Facebook Launches Collaborative Video App Riff To Rival Meerkat And Periscope

Meerkat, and Twitter's live video streaming app Periscope, have garnered a lot of attention in recent weeks, and now, Facebook has launched Riff, another video app with potentially viral growth.

Unlike Meerkat and Periscope, Riff isn't a live streaming app, but it allows multiple users to add footage to create a single collaborative video. You create a short video and add a few tags to it, your Facebook friends then see your video and are invited to add their own footage. Your friend's clip is then shared with his friends, so you could have a very large collaborative project very quickly.
