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.

TEDx events are fully planned and coordinated independently, on a community-by-community basis
