Twitch is testing subscriber-only streams

A Twitch channel subscription might soon get you considerably more than emotes, ad-free viewing and access to special chat rooms. The service is launching a beta for Subscriber Streams, or live broadcasts that are (you guessed it) limited to people with active subscriptions, mod privileges and VIP status. It won’t be thrilling if you don’t like paying for Twitch, but it could help creators who want to reward paying fans with behind-the-scenes specials, all-request game sessions and other perks. Non-subscribers will get a preview of these streams with immediate access if they choose to sign up.

On-demand videos will be available to subscribers, while clips won’t have restrictions.
