The platform is headquartered in San Francisco and was acquired by Amazon in 2014.

Twitch allows users to live stream video game play sessions, esports events, and various interactive content.

The platform also supports community engagement with chat features and social sharing, enhancing the viewer experience. In addition to gaming, Twitch hosts content related to creative arts, music, and "in real life" (IRL) streams, while maintaining a strong focus on gaming.
