In addition to monthly perks, Twitch Prime members get one free subscription per month they can use on their favorite streamer. As Twitch CEO Emmet Shear said during today's keynote, streamers still get paid for these subscriptions, so Twitch Prime is "literally giving your favorite streamer free money."

From Amazon's point of view, this is an easy way to grab up some new Prime members from the massive Twitch audience. On the Twitch side, users can still keep their current Turbo ad-free memberships at the $8.99 price point if they prefer, but they won't get all the additional benefits or early bird access that come with the Prime membership. New users can snatch up a free 30-day trial now. After that, Amazon Prime costs $10.99 per month or $99 annually. If you're already an Amazon Prime member, all you need to do is link your Twitch and Amazon accounts at twitchprime.com

To celebrate the launch, Twitch and Amazon will also be donating $100,000 to GameChanger charity for every 100,000 new subscriptions to any channel on Twitch -- regardless of whether you're using your free sub or a paid one.

Twitch Prime is live now in the US, UK, Canada, Germany, France, Italy and Spain.
