TED is a non-profit organization devoted to Ideas Worth Spreading. It started out in 1984 as a conference bringing together people from three worlds- Technology, Entertainment and Design.
Since then its scope has become ever broader. Along with two annual conferences - the TED Conference in Long Beach and Palm Springs each spring, and the TED Global Conference in Edinburgh UK each summer.
TED includes the award-winning TED Talks video site, the Open Translation Project and TED Conversations, the inspiring TED Fellows and TEDx programs, and the annual TED Prize.
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized. (Subject to certain rules and regulations.)
