Facebook will start showing ads after 20-seconds in videos and share the money with publishers, according to Recode. For now, Facebook will sell the ads and share 55% of revenues with the people who supply the videos — the same policy as YouTube.

Why this matters: In 2016, users were watching 100 million hours of Facebook videos per day, but most video publishers saw little ad revenue from their clips on Facebook thanks to Facebook's ban on "pre-roll" ads. His stance discouraged some publishers from sharing valuable content on Facebook.

Winners: Facebook users because publishers will put their most valuable content on Facebook. Publishers will make more money off Facebook videos if they can hold viewer attention.

Loser: YouTube.
