Facebook has begun testing out a new commenting feature on iOS and Android devices, allowing users to choose a custom colored background for their comment that all Facebook users will see underneath the original post. As of now, only "a small fraction" of users have noticed the new feature on mobile (via Evert Groot and The Next Web), so it appears this is just one of many early-on tests that Facebook performs in order to see how it might implement the new feature to a wider audience, or scrap it altogether.
Most recently, Facebook launched its new "Watch" tab on mobile devices, the web, and in Facebook's TV apps. The tab is full of Facebook-exclusive shows that are "made up of episodes -- live or recorded -- and follow a theme or storyline." Discovery is encouraged with user-specific recommendations, and a Watchlist allows users to save videos to watch at a later time.
In a separate report this week by Bloomberg, Facebook is said to be aggressively pursuing contracts with major record labels and music publishers in order to allow its users to legally upload videos with copyrighted music in them. The social network is willing to spend upwards of "hundreds of millions of dollars" in seeking these contracts, with negotiations having been ongoing for the past few months.
