Here's something I'd like you to look at and listen to too: http://www.nytimes.com/ref/multimedia/podcasts.html
As you can see this is an internet page with a list or directory of New York Times podcasts. I'd like you to listen to at least four different podcasts. Try and pick a variety of different kinds so you will get a better idea of how they are done. Making your own podcast as an assignment for the class will be something that we will be doing this semester.
