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.

The annual TED Conference and TEDGlobal Conferences invite the world's leading thinkers and doers to speak for up to 18 minutes. Their talks are then made available, free, at and through TED distribution partners.
