TED Talks

TED Ideas Worth Spreading makes the best talks and performances from TED available to the public, for free. 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).

More than 100 talks 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.

This video is on PhotoSynth—software which gathers video from all over the web and integrates it into what Blaise Aguera y Arcas, its architect, call “metaknowledge”.
