It's like a history podcast for things that exist in our minds.I've now caught-up with all the episodes and have been consistently listening for the past few years. This is a great podcast for anyone interested in Sci-Fi and fiction, including books, movies, plays, movies, whatever. Each episode focuses on some specific area (not necessarily a specific movie or book), and I love this. There is a bunch of research into the topic, and the quality and presentation is excellent.
