This is but a small sampling of Science Fiction and Fantasy podcasts, selected based on recommendations from the Reddit "SFF" community. I have not listened to these podcasts myself, and thus cannot attest to their quality or relevance for any particular research topic.
Geek's Guide to the Galaxy
- "Geek’s Guide to the Galaxy is a podcast that airs each week on Wired.com. The show is hosted by science fiction author David Barr Kirtley and produced by Lightspeed Magazine editor John Joseph Adams. Geek’s Guide to the Galaxy features conversations about fantasy & science fiction in books, movies, games, and comics, as well as related subjects such as science, history, and critical thinking."
Imaginary Worlds
- "Imaginary Worlds is a bi-weekly podcast about science fiction and other fantasy genres. Fantasy worlds may be set in distant planets or parallel dimensions, but they are crafted here on Earth and on some level relate to our daily lives. I talk with novelists, filmmakers, comic book artists, game designers and other creators about the craft of making fictional worlds. We also look at the fan experience, exploring what makes us suspend our disbelief, and what happens when that spell is broken.
What the SFF?!
- "Incoming transmission! Welcome to What The SFF, a new podcast hosted by Angry Robot Books.
