Twitch's latest test lets you preview channels without watching ads
 

Twitch has begun testing a new feature that could introduce you to great streamers you haven't seen before. Channel Switcher shows random channels as a carousel at the bottom of the screen. When you click on any of them, you'll be able to watch a one-minute preview of the streamer's content, enough to give you an idea of what they offer. The previews have no ads either, so you can channel surf undisturbed until you find something to watch. As Twitch explains, the feature will make it easier to figure out if you like a specific channel before committing.
