This week on Smart City, we're talking innovation with two inspired thinkers. First we'll speak with Chris Anderson. He's the editor-in-chief of Wired Magazine and is author of the book "The Long Tail,” which describes the new marketplace where niche markets - not mainstream products and services - are at the head of the demand curve. His next book, "Free", shows how the future of business has a price tag of $0.00.

We'll also have a conversation with Karen Gagnon. She heads Michigan's "Cool Cities" initiative. Karen hopes to ignite the passions of urban leaders with her conference. The Detroit conference will explore how cities are integrating innovation, social entrepreneurship, sustainability, arts and culture and business to create vibrant, creative economies.
