TED stands for technology, entertainment and design.
Each year, TED conferences bring together the world's most
innovative and thought-provoking doers and thinkers. These
visionaries are given a challenge: Give the talk of their
life in 18 minutes.
Join host Alison Stewart for some of those TED talks.
Ideas worth spreading -- it's the TED radio hour from NPR...
coming up in April Thursdays at 1pm and 7pm.
