The live streaming of video games is an activity where people broadcast themselves playing games to a live audience online. The practice became popular in the mid-2010s on the US-based site Twitch, before growing to YouTube, Facebook, China-based sites Huya Live, DouYu, and Bilibili, and other services. By 2014, Twitch streams had more traffic than HBO's online streaming service, HBO Go. Professional streamers often combine high-level play and entertaining commentary, and earn income from sponsors, subscriptions, ad revenue, and donations.

Livestreaming, live-streaming, or live streaming is the streaming of video or audio in real time or near real time. While often referred to simply as streaming, the real time nature of livestreaming differentiates it from other forms of streamed media, such as video-on-demand, vlogs, and YouTube videos.
