TED

TED is a small 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 in Long Beach and Palm Springs each spring, and the TEDGlobal conference in Oxford UK each summer.

I love TED talks, they're inspiring and give you a lot of new ideas plus in TED site you can download TED-talks and watch them whenever you want(That's what I do in my spare time). I always thought to myself that why we don't have such conference in Iran; It'll be fun and successful.
