To start a live broadcast, tap on your update status icon, then select the live video icon. From there, just type a quick into on what you’re broadcasting, and select the audience you wish to reach.
Discovery of live feeds takes place in your News Feed, and Facebook has worked in a subscribe option to push notifications next time that account broadcasts.
For now, live broadcasts are US-only, though Facebook says it’s working to roll it out worldwide “over the coming weeks.”
