TEDxLive is an extension of the TEDx program, launched by TED in 2010. TEDxLive events are TEDx events built around the live webcast of TED Conferences. TEDxLive events enable TED enthusiasts all over the world to experience live sessions of the TED Conference; events can be simple viewing events, and may also host live speakers. The event started at 18h30 with the session "The Earth" and ended after the last session of the day, around 03am.
