TED Radio Hour

Mondays from 10 a.m. to 11 a.m.
  • Hosted by Guy Raz

An idea is the one gift that you can hang onto even after you've given it away. Welcome to TED Radio Hour hosted by Guy Raz – 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.
