Ideas Worth Spreading is

the tagline for the TED website. And it's good to see a tagline with truth.

TED stands for Technology, Entertainment, Design. It started out (in 1984) as a conference bringing together people from those three worlds. Since then its scope has become ever broader.

The annual conference now brings together the world's most fascinating thinkers and doers, who are challenged to give the talk of their lives (in 18 minutes).

This site makes the best talks and performances from TED available to the public, for free. Almost 150 talks from our archive are now available, with more added each week. These videos are released under a Creative Commons license, so they can be freely shared and reposted.

Ted is a goldmine of ideas and information. For instance, below I've embedded the TED video of a talk by former MIT Media Lab director Nicholas Negroponte about the One Laptop Per Child project.
