Facebook teams up with Blizzard for streaming
Players of Blizzard titles, including World of Warcraft, Heroes of the Storm, Hearthstone, Diablo III, StarCraft II, and Overwatch, will be able to log into these games using their Facebook login. This will eventually pave the way for players to be able to "Go Live" with the touch of a button, broadcasting their gameplay session to their friends.
Friends will be able to spectate, comment, and subscribe to the broadcaster directly from their News Feed. All of this means that both streaming and spectating will be convenient and accessible. Many broadcasters take to Facebook to let friends know that they're broadcasting - soon they'll not only be informed automatically, but won't even have to visit another site to watch.
