TED is a nonprofit devoted to spreading ideas, usually in the form of short, powerful talks (18 minutes or less). TED began in 1984 as a conference where Technology, Entertainment and Design converged, and today covers almost all topics — from science to business to global issues — in more than 100 languages. Meanwhile, independently run TEDx events help share ideas in communities around the world. They are part of an international community that organizes TED-style events celebrating locally-driven ideas and elevating them to a global stage.

The talks are really inspiring, full of ideas worth spreading!
