TED (conference)

TED Conferences, LLC is an American-Canadian non-profit media organization that posts international talks online for free distribution under the slogan "ideas worth spreading". It was founded by Richard Saul Wurman and Harry Marks in February 1984 as a technology conference, in which Mickey Schulhof gave a demo of the compact disc that was invented in October 1982. Its main conference has been held annually since 1990. It covers almost all topics—from science to business to global issues—in more than 100 languages.
