Welcome, today you are part of a truly remarkable global phenomenon - TEDxYouthDay For a period of 24 hours all around the world thousands of young people are gathering in meetings just like yours because they believe in the power of ideas. So what is TED? TED started out as a conference for people from the worlds of Technology, Entertainment and Design, and has broadened ever since. In 2009 we launched a new program called TEDx, enabling anyone, anywhere in the world to host a TED-like conference. We at TED have had almost nothing to do with your event. We lent our name, our format, a few simple guidelines and some of our content. But the really hard work to make today happen has been down to your local organizer. And we're truly in awe of the passion and dedication they have shown to make something like this work. Today, on International Children's Day, TEDx organizers in over 60 different cities are hosting events that feature young people and their ideas. We thank you all for taking this time to come and be a part of this exciting conversation about ideas and our shared future and now, on with the show!
