Steam launched a game broadcast service

Valve introduced to the public its service streaming games.
Already, new Steam features are available in beta. You do not need third-party programs. Only the Steam client itself.
To take part in beta testing, go to your account settings:

Next, restarting Steam and installing its beta version, you can make broadcast settings. You can choose among the following options:
* Only friends whom I invite will be able to watch my streams;
* Friends can request permission to view the streams of my games (by default);
* Friends can watch streams of my games without asking permission;
* Any user can watch streams of my games (public broadcast, can be found in the game’s hub).
Broadcasting begins as soon as someone starts watching it.
To join watching a broadcast, find it in the hub, or in your friend’s profile.

At the moment, viewing the broadcasts is available through the beta version of the Steam client, Google Chrome and Apple Safari browsers. Also, there is no record of broadcasts, as well as monetization. May appear in the future.

You can stream not only games, but anything you want, such as the desktop, the process of developing a game or program.
