Though it’s still far from YouTube, Facebook fired a shot across its competitor’s bow by saying it now serves up a billion native video views per day. In addition, its latest update has a YouTube-like view counter for public videos, making it easier to find popular selections or see how your own uploads are doing. Facebook said two-thirds of video views were from mobile devices, a stat no doubt helped significantly by the new auto-playing feature that’s on by default. A recent video ranking change also gives frequent video watchers more options. But as the NY Times pointed out, Facebook’s social nature can also send a video viral quickly.
