About TEDx, x = independently organised event
In the spirit of ideas worth spreading, TEDx is a program of local, self-organised 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-organised events are branded TEDx, where x = independently organised TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organised.* (*Subject to certain rules and regulations)
