Let’s see, my favorite podcasts:
SU&SD, obviously. I mean, seriously.
The Dice Tower, not terribly surprising, I’m sure.
You Must Remember This, a history of Hollywood’s first 100 years. Host Karena Longwood does seasons that usually focus on a topic (such as MGM stories, tales of Hollywood during WWII, Charlie Manson’s Hollywood), are well researched and very illuminating about what actually happened, separating fact from fiction.
Jay and Miles X-plain the X-Men, a great dissection of some great comics by some folks who clearly love the material.
Futility Closet - A Podcast of Curiosities, where the husband/wife host discuss some weird or interesting story from history, like a professional time-carrier in Victorian London, Japanese Fire Balloon Attack on US Soil, amazing hoaxes, strange historical mysteries and more. Usually ends with a lateral thinking puzzle.
Movie Sign with the Mads - A movie review podcast starring the MST3K’s original ‘mads’, Frank Coniff and Trace Beaulieu (and also Carolina Hidalgo). Funny banter from two guys who still love movies, despite MST3K (or perhaps because of it). They do new movies and sometimes stuff from Netflix (but all big movies).
Music In Widescreen - Prog Rock Podcast - Another Husband/Wife team, covering the Prog Rock scene. Basically their live radio show, runs about three hours (so, you know, about four prog songs LOL).
KaijuCast - The Godzilla and Kaiju podcast. Nuff said.
This is only a Test - the official podcast of tested.com, mostly about tech items of the week.
There are others, but these are the ones on regular rotation for me.
