TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TED Talks videos and live speakers combine to spark deep discussion and connection.
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-organised.
