Live video won't be left out either. If a publisher has at least 2,000 followers and has hit 300 concurrent live viewers in a "recent live video," they'll be able to insert ads as well -- assuming the broadcast has been running for at least four minutes and has 300 viewers.

As far as revenue split goes, like the rumors predicted, publishers will net 55 percent of proceeds while Facebook grabs the rest. That's quite a bit different versus the social network's ad split for instant articles where the publisher would get between 70 and 100 percent of the cash.

With Facebook pushing into the TV space, expect to see even more of this in the future as it tries courting additional professional video producers.
