TED Conferences LLC is an American media organization that posts talks online for free distribution under the slogan "ideas worth spreading". TED was conceived by Richard Saul Wurman in February 1984 as a conference; it has been held annually since 1990. TED's early emphasis was on technology and design, consistent with its Silicon Valley origins. It has since broadened its perspective to include talks on many scientific, cultural, political, and academic topics. It is curated by Chris Anderson, a British-American businessman, through the non-profit TED Foundation since July 1, 2019.
