We are TEDxPerth, where x = independently organised event. About TED TED is a non-profit devoted to Ideas Worth Spreading. Started as a four-day conference in California 26 years ago, TED has grown to support those world-changing ideas with multiple initiatives. At TED, the world's leading thinkers and doers are asked to share their idea, usually in the form of a short powerful talk. Talks are then made available, free, at TED.com.
