TED

TED Conferences, LLC is an American-Canadian nonprofit media organization that posts international talks online for free distribution under the slogan "Ideas Change Everything". It was founded by Richard Saul Wurman and Harry Marks in February 1984 at 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 many topics—from science to literature to business to global issues—in more than 100 languages.
