The online retailing giant said Tuesday that it had bought Curse, an online media and gaming community. Financial details of the acquisition were not disclosed.

Amazon acquired Twitch, used by gaming enthusiasts to watch others play online games such as Minecraft and Call of Duty, for around $1 billion in 2014. Twitch gained traction before the rise of live video streaming services like Facebook Live and Twitter’s Periscope.

Twitch now has 100 million users.

Founded in 2006, Curse operates 65 gaming sites including ones focused on news, guides, tools, and online communities that attract more than 30 million people monthly. The company had raised close to $60 million in venture capital.

“We’ve long been fans of Curse, which is an innovator in the games industry with a strong culture built around its offerings—from Curse Voice and Curse Client to Gamepedia,” Emmett Shear, Twitch’s CEO, said in a statement. He added that Curse’s tools and communities would be made available to Twitch’s users.

Adding more gaming tools and communities could help Twitch in its competition with Google’s video streaming service, YouTube. YouTube introduced its own gaming-focused live-streaming service last year in an attempt to compete with Twitch.

Twitch has also been looking to expand beyond just gaming and into other areas like cooking and music.
