Lifecasting is broadcasting a person’s day-to-day existence over the Internet.
The term is credited to Justin Kan, founder of Justin.tv, a website for distributing and viewing streaming video. In 2007, Justin launched Justin.tv to digitally share his own life twenty-four hours a day, seven days a week. He called his experiment in reality television "lifecasting" and worked with partners to develop a custom head-mounted camera and software that would reduce the cost of streaming video down to less than a penny an hour, per user. Today the site is one of the world's largest streaming video platforms, allowing visitors to chat with other viewers who are watching the same live video stream.
Since Kan coined the term, the definition of lifecasting has since broadened to include any attempt a person makes to document and share the events of an ordinary day. It is expected that as consumer computing continues to move from desktop to mobile to wearable computing devices, the opportunities for the average person to engage in lifecasting activities will also increase.
