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.

The two annual TED conferences, on the North American West Coast and in Edinburgh, Scotland, bring together the world’s most fascinating thinkers and doers, who are challenged to give the talk of their lives (in 18 minutes or less).

On TED.com, we make the best talks and performances from TED and partners available to the world, for free. More than 1400 TED Talks are now available, with more added each week. All of the talks are subtitled in English, and many are subtitled in various languages. These videos are released under a Creative Commons BY-NC-ND license, so they can be freely shared and reposted.
