What stands out to me is the minutes per viewer. Of the 10 sites listed Facebook is second to last with 21.7 minutes per viewer. If you sort that list by the total amount of time spent watching videos - Facebook ranks #8.
Viewers spend over 71 times as long on Google properties. It may be a while before FB catches up.
