TED (Technology, Entertainment, Design) is an American-Canadian non-profit media organization that posts international talks online for free distribution under the slogan "ideas worth spreading". TED was founded by Richard Saul Wurman and Harry Marks in February 1984 as a tech conference, in which Mickey Schulhof gave a demo of the compact disc that was invented in October 1982. It has been held annually since 1990. TED covers almost all topics – from science to business to global issues – in more than 100 languages. To date, more than 13,000 TEDx events have been held in at least 150 countries.
The main TED conference is held annually in Vancouver, British Columbia, Canada at the Vancouver Convention Center. Prior to 2014, this conference was held in Long Beach. TED events are also held throughout North America, Europe and Asia, providing live broadcasts of the seminars. They cover a wide range of topics in scientific and cultural research and practice, often through storytelling. Speakers are given a maximum of 18 minutes to present their ideas in the most creative and engaging ways they can.
Speakers who have spoken include Bill Clinton, Jane Goodall, Al Gore, Gordon Brown, David Cameron, Billy Graham, Richard Dawkins, Bill Gates, Bono, Google founders Larry Page and Sergey Brin, and many others. Nobel Prize winners. TED's current manager is former computer journalist and magazine publisher, Chris Anderson.
Since June 2006, TED Talks has been made available for free online viewing, under Attribution - Non-Commercial - Non-Derivative terms under a Creative Commons license, through TED.com. As of March 2016, more than 2,400 TED Talks are available for free access on the website. In June 2011, the combined views exceeded 500 million, and by November 2012, TED Talks were watched over a billion times worldwide.
However, not all TED Talks are equally popular. Talks shared by scholars tend to be watched more, while art and design videos tend to be watched less than average.
