TED Radio Hour

Saturdays from 4 a.m.-5 a.m. and Sundays from noon-1 p.m.
  • Hosted by Guy Raz

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.
