AppleInsider:

Revealed in early February, and launched on Tuesday, Facebook Video is a free app for the fourth generation Apple TV, with an emphasis on video shared across the social network. The app pulls videos from user feeds presented mostly without user commentary beyond emoticons.

In our testing, Facebook’s Video app works well, and wasn’t impaired by lengthy buffering. However as far as quality goes, what you see is restricted by how and when the video was sent to Facebook.

I’m not a heavy Facebook user but I can see how this could be very popular among those who like watching videos on and from the site.
