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.
Our event at TEDxTallaght broadcast session 4 (The Lab) and session 5 (The Earth). Attendees dropped in and out at their leisure enjoying the global twitter conversation and sipping a coffee. The event was relaxed, with an intimate feel in the room.
