TED (Technology, Entertainment, Design) is a media organization which posts talks online for free distribution, under the slogan "ideas worth spreading". TED was founded in February 1984 as a conference, which has been held annually since 1990. TED's early emphasis was technology and design, consistent with its Silicon Valley origins, but it has since broadened its focus to include talks on many scientific, cultural, and academic topics.
