There are about seven hundred thousand active podcasts available to anyone with a computer or a smartphone, in more than 100 languages. And people DO listen--at the rate of 62 million people per week, in the US alone. What makes a good podcast? And what do podcasts provide that is different from broadcast media? We pose those questions to WYPR original podcasters, Aaron Henkin, creator of ‘Out of the Blocks’ and the makers of Truth and Reconciliation, Taya Graham and Cianna Greaves.
