TED Radio Hour

Sundays at 5 pm

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.
