This year, for the first time ever, the TED Prize went not to an individual, but to an idea on which our planet's future depends: the City 2.0. In the tradition of our TEDxYouthDay, TEDxChange, and TEDxWomen initiatives, comes TEDxCity2.0: A day of urban inspiration, a day when TEDx communities around the world (like us!) will host an event to share the powerful narratives of urban innovators and organizers, stewards and artists, builders and taste makers.
