Live-stream

Live streaming refers to online streaming media simultaneously recorded and broadcast in real time to the viewer. It is often simply referred to as streaming.

Live stream services encompass a wide variety of topics, including social media, video games, and the sex industry. Apps such as Facebook Live, Periscope, and 17 include the streaming of scheduled promotions and celebrity events as well as streaming between users. Sites such as Twitch.tv have become popular outlets for watching people play video games, such as in eSports, Let's Play-style gaming, or speedrunning. Lifecasting or lifestreaming is a real-life activity facilitated by live streaming.

User interaction via chat rooms forms a major component of live streaming. Facebook Live and Periscope also include the ability to talk to the broadcaster or participate in conversations in chat. An extreme example of viewer interfacing is the social experiment Twitch Plays Pokémon, where viewers collaborate to complete Pokémon games by typing in commands that correspond to controller inputs.

In the field of social media, the term "live media" refers to new media that use streaming media technologies for creating networks of live multimedia shared among people, companies and organizations. Social media marketer Bryan Kramer describes live streaming as an inexpensive "key marketing and communications tool that helps brands reach their online audience." Users can follow their friends' live video "shares" as well as "shares" related to specific content or items. Live media can be shared through any Internet website or application; thus, when people browse on a specific website, they may find live media streams relevant to the content they look for.
