If you've not listened to Serial Podcast (at least season one) yet you need to stop what you are doing and go get it on your phone. The podcast resulted in multiple new podcasts about similar cases and many of these are most interesting with several podcasts followed up on the Serial case. Serial did a 2nd podcast season which was interesting too.
The same team has split off a new podcast (involving some of the same people) called S-Town which you can find here. S-Town is about a person and people in a town in Alabama and after listening to all of it, I'm still trying to process it.
Listening to podcasts is a great alternative to audiobooks while driving and I find myself going back and forth between the two. I've about given up on the radio and in particular sports radio.
