Justin.tv was a website created by Justin Kan, Emmett Shear, Michael Seibel, and Kyle Vogt in 2007 to allow anyone to broadcast video online.

[3] The original Justin.tv was a single channel featuring founder Justin Kan, who broadcast his life 24/7 and popularized the term lifecasting.

Broadcasts containing defamation, pornography or copyright violations, or encouraging criminal conduct, were prohibited by Justin.tv's terms of service.

[5] Justin.tv moved its gaming section to a new site called Twitch.tv in June 2011,[6] and the parent company of Twitch.tv and Justin.tv rebranded as Twitch Interactive in February 2014.

[1] The Justin.tv services and brand were officially shut down in August 2014 so that the company could focus on Twitch, which was then acquired by Amazon later that month.

[11] Kan would be streaming his entire life (minus bathroom and bathing breaks) via a camera attached to his hat and a laptop rig created by Justin.tv co-founder, Kyle Vogt.

Occasionally, viewers would attempt to troll Kan by falsely reporting him to the police ("swatting") or by sending large delivery orders to his apartment,[12] two online harassment methods which remained popular long after the site's closure.

Notable figures include iJustine, who continues to make YouTube videos and has over 7 million subscribers; Mooncricket Films, a San Francisco-based lifecaster active since Justin.tv's inception;[14] and JoeInIraq, who uniquely streamed his experiences in Iraq during 2007-2008, offering a rare glimpse into soldiers' downtime in a war zone.

[17] On March 14, 2008, Justin.tv added selectable Categories for broadcasters including: Featured, People & Lifecasting, Sports, Music & Radio, Gaming, News & Tech, Animals, Entertainment, Divas & Dudes.

On March 21, 2007, the spoofer called the San Francisco Police Department and filed a false report about a stabbing in the apartment.

In July 2008, TheDefaced.org, a computer security group, released a non-malicious cross-site scripting (XSS) worm onto the Justin.tv site.

[36] In 2011, the American sports promotion company Zuffa sued Justin.tv for its users using the streaming service to watch pay-per-view matches of the UFC, violating certain trademark and copyright laws.

[38] On November 19, 2008, 19-year-old Abraham K. Biggs committed suicide while broadcasting to a room full of viewers on his Justin.tv channel by ingesting an overdose of opiates and benzodiazepines.

[42] Justin.tv CEO Michael Seibel stated, We regret that this has occurred and respect the privacy of the broadcaster and his family during this time.
