Amazon-owned live video streaming giant Twitch made one of its biggest announcements of the year on Wednesday as it revealed more than 20 new extensions to help content creators increase engagement and interaction.

The “Gear on Amazon” extension lets live streamers earn revenue from Amazon’s affiliate program.

Called “Twitch Extensions,” the new toolset allows third-party developers to create add-ons that live video streamers can use on their channel pages to help better engage with their fans.

“Twitch Extensions will put you at the heart of the next evolution in live streaming,” Ryan Lubinski, product manager for Extensions at Twitch, said at an event in Seattle at Amazon’s HQ on Thursday. “Extensions are live apps for live streams, created by the community, for the community, and integrated directly on Twitch. They are flexible, dynamic, easy to build, and easy to use.”

There are more than 20 available extensions “coming soon,” Twitch said today. They range from “Leaderboard by Muxy,” which automatically displays a channel’s top five cheerers, to “Schedule by Layer One,’ which shows viewers scheduled Twitch events. Polls, virtual pets, interactive game information, and other overlays can also now be added. There are also extensions for specific games, like “MasterOverwatch by Master Network,” an on-screen statistics overlay for Overwatch broadcasters.

Kathy Astromoff, head of Twitch’s developer platform and a game industry veteran, said she’s never been as excited for a reveal event than Thursday.

“Today is a watershed moment in how developers, streamers, and Twitch can build our shared community together,” she said.

Twitch Extensions also offers a new way for developers and streamers to make money. “Gear on Amazon” is an extension that lets streamers surface Amazon products on their stream and earn commission through Amazon’s affiliate program. They can select different products to promote from the Amazon catalog and create a “Gear on Amazon” list from their Twitch dashboard alongside other extensions.

“Many streamers have such strong connections with your communities that you can earn a living on their support,” Astromoff said. “Our mission at Twitch is to build tools and services that help even more streamers do this. But we can’t do it alone — developers, we need your help.”

Third-party developers can build extensions for creators from Twitch’s updated Developer Portal. Twitch plans to share more about the new extensions at its TwitchCon Developer Day in October.

At the launch event in Seattle — where the big PAX gaming convention is being held in town this weekend — there were plenty of Twitch employees who traveled to the event. Attendees ranged from developers to broadcasters to other people working in the gaming industry.

Twitch, acquired by Amazon in 2014 for nearly $1 billion, is traditionally known for its game streaming platform — there were 2.2 million Twitch streamers in 2016 — but the company is also expanding into other verticals like arts, cooking, vlogging, and more. The company has grown from 200 employees at the time of Amazon’s acquisition to 1,200 today.

    perks, get class info, and more – all seamlessly incorporated into the stream.
