I want to check out some of the ones Steve mentioned!
I regularly listen to:
What Happened When? with Tony Schiavone--mostly about old NWA and WCW stuff, but he's currently an AEW commentator so they touch on current stuff, too.
The Weekly Planet--pop culture stuff, mainly comic book movies but they'll get into other typical nerdy things like Star Wars and such.
83 Weeks with Eric Bischoff--another wrestling podcast, mostly about WCW but occasionally TNA or other things.
Cinemassacre Podcast--fairly new, mostly about movies and games and music and cryptozoology thus far.
The Holy Post--the Vegetales guy and a bald guy and an interchangeable token female talk about current events pertaining to evangelicals and butt news.
IYH Wrestling Radio--the greatest pro wrestling podcast in existence
Voxology--covers different stuff, theology, deconstructing modern evangelicalism, etc.
The Completely Unnecessary Podcast--emphasis on video games but sometimes other pop cultury things
Steve and Larson's Going in RAW! --some news but mostly recaps of wrestling shows, so I don't have to actually watch them
Player One Podcast--probably my favorite video game related one. Talk some video game news and about what hey are currently playing, etc.
Retronauts--focus on one particular old game or old video game series for an episode.
...I'm probably forgetting some stuff, but those are basically all the ones that I listen to consistently. There are others that I listen to occasionally depending on the topic, etc.
