TED: Ideas Worth Spreading

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 to include eight themes, including business.  On TED.com, there are more than 900 TEDTalks available for free!  Vidoes are less than 18 minutes.  Be sure to check out the TEDWomen section!
