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 non-live broadcast forms of streamed media such as video-on-demand, vlogs and video-sharing platforms such as YouTube and TikTok.
Livestreaming services encompass a wide variety of topics, including social media, video games, professional sports, and lifecasting. Platforms such as Facebook Live, Periscope, Kuaishou, Douyu, bilibili, YouTube, and 17 include the streaming of scheduled promotions and celebrity events as well as streaming between users, as in videotelephony. Livestreaming sites such as Twitch and Kick have become popular outlets for watching people play video games, such as in esports, Let's Play-style gaming, or speedrunning. Live coverage of sporting events is a common application.
