TED (Technology, Entertainment, Design) is a global set of conferences run by the private non-profit Sapling Foundation, under the slogan “Ideas Worth Spreading”. TED was founded in 1984 as a one-off event; the annual conference series began in 1990. TED’s early emphasis was technology and design, consistent with its Silicon Valley origins, but it has since broadened its focus to include talks on many scientific, cultural and academic topics. The main TED conference is held annually in Vancouver, British Columbia, and its companion TEDActive is held in Whistler, B.C. Prior to 2014, the two conferences were held in Long Beach and Palm Springs, California, respectively. TED events are also held throughout North America and in Europe and Asia, offering live streaming of the talks. They address a wide range of topics within the research and practice of science and culture, often through storytelling. The speakers are given a maximum of 18 minutes to present their ideas in the most innovative and engaging ways they can. Past speakers include Bill Clinton, Jane Goodall, Malcolm Gladwell, Al Gore, Gordon Brown, Richard Dawkins, Bill Gates, Bono, Mike Rowe, Google founders Larry Page and Sergey Brin, and many Nobel Prize winners. TED’s current curator is the British former computer journalist and magazine publisher Chris Anderson. Since June 2006, the talks have been offered for free viewing online, under an Attribution-NonCommercial-NoDerivs Creative Commons license, through TED.com. , over 1,900 talks are freely available on the website. In June 2011, the talks’ combined viewing figure stood at more than 500 million, and by November 2012, TED talks had been watched over one billion times worldwide.
