TED Radio Hour, hosted by Guy Raz, is a journey through fascinating ideas: astonishing inventions, fresh approaches to old problems, new ways to think and create.

Based on Talks given by riveting speakers on the world-renowned TED stage, each show is centered on a common theme – such as the source of happiness, crowd-sourcing innovation, power shifts, or inexplicable connections – and injects soundscapes and conversations that bring these ideas to life. TED Radio Hour is a co-production of NPR and TED.
