TED -Technology, Entertainment, Design is a non-profit media organization which posts videos of powerful talks online, for free distribution, under the slogan "ideas worth spreading", ideas which are known to change perspectives and provide food for thought. TED was founded in February 1984 as a conference, which has been held annually since 1990. TED's early emphasis was technology and design, but it has since broadened its focus to include talks on many scientific, cultural, and academic topics.
TED is synonymous with world-changing ideas with multiple initiatives. At TED, people who are great in their thoughts and actions, are asked to give the talk of their lives in 18 minutes. Talks are then made available, free, at TED.com. TED speakers have included Bill Gates, Jane Goodall, Elizabeth Gilbert, Sir Richard Branson, Benoit Mandelbrot, Philippe Starck, Ngozi Okonjo-Iweala, Isabel Allende and former UK Prime Minister Gordon Brown. Two major TED events are held each year: The TED Conference takes place every spring in Long Beach, California (along with a parallel conference, TEDActive, in Palm Springs), and TEDGlobal is held each summer in Edinburgh, Scotland.
