About TEDx, x=independently organized event
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.*
