Ok, I’ll play. What is it?

@jeremycherfas Intriguing. I was going to ask you how podcasts and radio shows are different, but instead I'll try to answer that question: (1) Podcasts are often more produced and polished. It's hard to imagine something like S-Town or Serial as a radio show. (2) Podcasts assume a level of continuinty by the listener. Even the couple-of-nerds-sitting-around-talking genre tend to assume that listeners listen to every minute of every episode. Not true in talk radio -- far from it.

@jeremycherfas ... that said, sometimes podcasts can be very radio-like, and vice-versa. I remember hearing a long excerpt from a talk radio program that Studs Terkel did in the 60s -- a half-century ago, and it sounded like a podcast. Studs and a couple of co-hosts shooting the breeze intelligently and informatively, in a deceptively casual fashion. And I heard the excerpt on a historical podcast -- full circle!
