After last month Facebook introduces article trends, now they made a new feature called Trending Video. Basically similar to article trend, Facebook users will see some popular videos posted by their friends and may be missed.
The videos will be displayed based on what users friend watch. For that Facebook also empowers the Open Graph. Thus, the content may not seen will be displayed on the user news feed.
Some people say quite disturbed by articles trend feature that are considered less important. Therefore have to wait how people responses on the video trend feature.
