In the spirit of ideas worth spreading, TEDx is a program of local,
self-organized events that bring people together to share a TED-like
experience. At a TEDx event, TEDTalks video and live speakers combine to
spark deep discussion and connection in a small group. These local,
self-organized events are branded TEDx, where x = independently organized
TED event. The TED Conference provides general guidance for the TEDx
program, but individual TEDx events are self-organized.* (*Subject to
