User:93/Live streaming

Live streaming refers to online streaming media simultaneously recorded and sent in real time to the viewer. It is often simply referred to as streaming, however, this term is ambiguous due to the fact that "streaming" may refer to any media delivered and played back simultaneously without requiring a completely downloaded file. Non-live media such as videos on demand and regular YouTube videos are streamed, but not live streamed.

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.

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.

Social media
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.

Live media can include coverage of various events such as concerts or live news coverage viewed using a web browser or apps such as Snapchat. James Harden and Trolli promoted an upcoming NBA All-Star Game through Snapchat.

Periscope
In March 2015, Twitter launched a live streaming app called Periscope. Normally, users would see a hyperlink attached to their broadcast, directing people to a new tab. Using Periscope, videos appear live on the timeline. If the user has allowed the site to share information, others can see where the user is streaming from. During the broadcast, users can comment, talk to the broadcaster, or ask questions. Kayvon Beykpour, CEO of Periscope, and Dick Costolo and Jack Dorsey, CEOs of Twitter, all shared a common goal—to invent something that would merge both teams into one instead of as partners. The team wanted to give people more accessibility for both Twitter and Periscope. Their solution was a combination of live streaming and Twitter.

Facebook Live
Facebook introduced a video streaming service, Facebook Live to select individuals in August 2016, and it to the public in January. Facebook Live allows Facebook users to include their own "reactions" when someone is broadcasting.

YouTube live streaming
YouTube was purchased by Google in 2006, and the pair subsequently announced their live streaming app. Like Periscope, users can comment on the broadcast. Unlike Periscope, live streams on YouTube can be saved and any user can access them through the app. Bronstein stated that this would be the perfect opportunity for "creators" to interact with their fans.

Video games
Live streaming playing of video games gained popularity during the 2010s. David E. Walt referred to the site Twitch.tv as "the ESPN of video games." The website spawned from and grew to overshadow Justin.tv, and was purchased by Amazon.com at the end of 2014 for $970 million USD. Other video-game oriented streaming websites include Smashcast.tv, which was formed after the merging of Azubu and Hitbox.tv.

A notable live streamed event is Games Done Quick, a charity speedrunning marathon hosted on Twitch. Viewers are encouraged to donate for incentives during the stream such as naming characters in a run, having the runners attempt more difficult challenges, or winning prizes. Over $10 million has been raised across sixteen marathons.

Professional streamers generate revenue from viewer subscriptions and donations, as well as platform advertisements and sponsorships from eSports organizations. The audiences of professional gaming tournaments are primarily live stream viewers, and have been broadcast through YouTube's streaming service as well.

Webcam modeling
Webcam models perform through live webcam footage. They often perform services of a sexual nature, and can in this context be considered as part of the sex industry.

Crime
Many instances of crimes such as rape and assault, along with suicides, have been streamed live, leaving little to no time for administrators to remove the offending content. Live streamed crimes became a trend in the mid-2010s with widely reported incidents such as assaults and suicide streamed through Periscope in 2016 and the kidnapping of a man in Chicago streamed through Facebook Live in 2017.
