I am just going to recommend some podcasts which haven't been mentioned before in this thread (At least here.) and only doing the comedy ones
Loading Ready Run has a few podcasts that I listen to:
Sidewalk Slam a Wrestling storyline podcast which has been running for the last year and actually got me into actually watching WWE.
AnoAni (I still don't remember the name of the anime I saw that day.): Seasonal anime reviews/previews.
Qwerpline: Is an improve Comedy podcast of a Talk Radio show around 20-30 minutes an episode and amazingly funny with running jokes and characters. Watching the youtube versions is also great since they have original drawings for all the products and services mentioned in the broadcast.
TapTapConcede: Don't listen to this one but it is a Magic the Gathering podcast so I am sure that some people here might like it. They also do a livestream of the Pre-Prerelease of new sets.
I would also suggest all of Nerdyshow Podcasts but I will highlight a couple of them.
Dungeons and Doritos: Fantasy RPG podcast started off as mostly jokey but can also get all serious. One of the initial characters is Chair a naked dwarf who was once a literal Chair.
Friday Night Fanfiction: People originally from OCRemix reading the worst of the worst fan fiction in a drinking game.
Ghostbusters Ressurection: A tabletop RPG Podcast using the classic Ghostbusters RPG from the 90s set in Central Florida. Currently on its third season of adventures.
Lightning Dogs: The writers room of creating a pitch bible for the best 80s Action cartoon which doesn't yet exist. Where Anthropomorphic dogs tare up a mad max style wasteland against the evil Glampyre.
Other podcasts not part of a big group:
So Many Levels: Another D&D podcast - Christiana Ellis is the DM and Jared Axelrod is a player and they are Authors who podcast their work back in 2005-ish.
Fish Shark Marketting: An improve comedy podcast by Jim Sterling and Conrad Zimmerman as marketing executives solving problems like Bostin's drug crsis and selling Dean Cain's Garbage Juice.
God Awful Movies: going through awful Christian movies and other movies including the worst one Vaxxed (Andrew Wakefield using autistic kids as props to scare parents.)
Freinds from the internet: Dave (from Fast Karate) other podcast with Graziella. "Downtown nemuru Ultimate Anime sleepytime Challenge" is the cutest thing because Dave tries to make Graziella guess between real and fake anime titles.
Jimquisition: The Jimquisition podcasts are great you have the videogame one (Podquisition) and Conrad Zimmerman from fistshark marketting also joins Jim with "The Spin-off Doctors" where they review videogame movies. Where postal is actually funny because they reviewed it the week after reviewing Pixels.
