TED Radio Hour

Fridays, 6:00-7:00pm | Saturdays, 7:00-8:00pm

The weekly one-hour program is a captivating collaboration between TED and NPR. Using TED Talks as a launching point to explore the best ideas in technology, entertainment, design and much more, each approach to every idea is different, and each is fascinating listening.

Host Guy Raz interviews the guests, delving deeper, dissecting the speaker's ideas and posing probing questions you’d like to hear answered. Topics explored include mankind's place in the universe and space, how the sounds around us affect our behavior and why there is power in failure.
