How to disable Steam broadcasting?

I enabled Steam broadcasting because it was an annoying option in my way on the in-game Steam menu, although once I enabled it I realised I did not know how to disable it. How do I disable Steam broadcasting?

In the client, go in the Settings panel, Broadcast's tab.

Here's the support page for broadcasting on steam :

The first time a friend requests to watch your game you'll be presented with the broadcast privacy settings. To make a change at any time, access the Steam Client's Settings panel and select the Broadcast tab to view your privacy settings.

Available settings:

Broadcast is disabled
Friends can request to watch my games (default)
Friends can watch my games
Anyone can watch my games (public broadcast, can be found in the game hub)
