Watch Your Friends Play With Steam Broadcasting

It's currently in beta, but Steam users can now broadcast their gameplay for friends or strangers.

Starting today you can watch your friends' games with the click of a button via Steam Broadcasting, now available in beta. When you see a friend in game, simply click on "Watch Game" from their profile or from the Steam Client Friend's List to open a window into their gameplay — no game ownership, special fees, or additional apps required.
