TED: a video collection of our world’s greatest thinkers

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. The annual TED conferences, in Long Beach/Palm Springs and Edinburgh, 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. Almost 900 TEDTalks 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.

Our mission: Spreading ideas.

We believe passionately in the power of ideas to change attitudes, lives and ultimately, the world. So we’re building here a clearinghouse that offers free knowledge and inspiration from the world’s most inspired thinkers, and also a community of curious souls to engage with ideas and each other.
