Richard Florida on cities as "the third great business model"

Today's BBC In Business had a gripping and wide-ranging interview with Richard Florida [link to podcast], Professor of Business and Creativity at the Rotman School of Management, in the University of Toronto, who argues enthusiastically about the benefits of immigration, about successful cities like London and San Francisco as illustrating the "third great business model" (he is not a fan of the technology driven "death of distance"), and about popular music as a historically important driver of technologies and development (radio, TV, phonograph, CD, iPOD etc). Richard Florida's website is worth browsing, and below is a video of a one hour talk he gave at Google's New York Office on 5 April 2008.
