"TED
is a nonprofit devoted to Ideas Worth Spreading. It started out (in 1984) as a
conference bringing together people from three worlds: Technology,
Entertainment, Design. Since then its scope has become ever broader.
Along with two annual conferences -- the TED Conference on the West Coast each
spring, and the TEDGlobal 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." From About TED
