About TEDx.
TEDx was created in the spirit of TED’s mission, “ideas worth spreading.” The program is designed to give communities, organizations and individuals the opportunity to stimulate dialogue through TED-like experiences at the local level. At TEDx events, a screening of TEDTalks videos — or a combination of live presenters and TEDTalks videos — sparks deep conversation and connections. TEDx events are fully planned and coordinated independently, on a community-by-community basis.
