During the Twitch Town Hall at PAX East on Friday they announced ad-free subs. Starting today, Twitch Partners have the option to include ad-free viewing alongside all of the other awesome benefits viewers will get with a Channel Subs.
Partners can choose whether or not to include Ad-Free Viewing in their channel’s Subscriber benefits, so make sure to double check for each channel before you subscribe. This option is available to all Partners with a subscription option, regardless of how long they’ve been a Partner or how many Subscribers they have.
Partners can manage ad-free viewing settings and sub benefits on the Partner Settings tab on the Broadcaster Dashboard.
