TED is an annual event where some of the world’s leading thinkers and doers are invited to share what they are most passionate about. “TED” stands for Technology, Entertainment, Design — three broad subject areas that are, collectively, shaping our future. And in fact, the event is broader still, showcasing ideas that matter in any discipline. Attendees have called it “the ultimate brain spa” and “a four-day journey into the future.” The diverse audience — CEOs, scientists, creatives, philanthropists — is almost as extraordinary as the speakers, who have included Bill Clinton, Bill Gates, Jane Goodall, Frank Gehry, Paul Simon, Sir Richard Branson, Philippe Starck and Bono.

TED was first held in Monterey, California, in 1984. In 2001, Chris Anderson’s Sapling Foundation acquired TED from its founder, Richard Saul Wurman. In recent years, TED has expanded to include an international conference, TEDGlobal; media initiatives, including TED Talks and TED.com; and the TED Prize. TED2010, “What the world Needs Now,” will be held Feb 9-13, 2010, in Long Beach, California, with a simulcast event in Palm Springs, California. TEDGlobal 2009, “The Substance of Things Not Seen,” will be held July 21-24, 2009, in Oxford, UK and TEDIndia will be held in November 2009.
