All TEDx event names follow the same convention: a name beginning with TEDx, followed by a location-based descriptor such as the name of your city, school, neighborhood or organization. There are no exceptions to this rule.
Prior to applying, you need to check to see if the name you want is available. Some names -- such as major cities -- are reserved to distribute at the discretion of TEDx staff. We do co-brand TEDx events with colleges and universities. In the case of corporate events (which are held internally, not open or promoted to the public) we may co-brand.
