Continent by continent, TEDGlobal talks

TEDGlobal has been held in Oxford, England; Arusha, Tanzania; Mysore, India; and Edinburgh, Scotland — with speakers from a wide range of other countries. In other words, it's a global affair. As we prepare for TEDGlobal 2013: "Think Again," kicking off on June 10, we thought we'd take a closer look. Here, go around the world in less than 180 minutes with TEDGlobal talks.
