what is the nature of talk radio in other countries?
Here in the U.S. we have pretty great talk radio. It is where the host talks on the radio, sometimes with guests, and the audience at home can call in on the telephone and talk with the host and guests on the air. I've done it many times, it's very cool. I'm thinking it would be a great way for TED conversation folks to spread their ideas, it's very challenging because you have to think on your feet, sometimes in front of an audience of many thousands of people.
Do other countries have similar "talk radio"?
