Throughline has been my favorite since it launched a few years ago. The hosts take a deep dive into the historical events leading up to topical events of the present weaving a thread through them, hence the name.
Some of the examples are the history of policing in the US and how capitalism became the dominant economic system.
I am surprised some of the big ones haven’t been mentioned yet -
Radiolab - Not really sure how to describe this podcast. It’s superb journalism at its core. They do both short and multi-episode long form about a variety of topics from science to history to current events. For example, how dinosaurs died when the asteroid hit earth, the story of a Guantanamo convict with the same name as the host, and how poorly computer databases are designed for names that are outside the norm.
Planet Money - An excellent economics podcast where complex topics are distilled in fairly short episodes. They recently released a completely AI generated episode which was incredibly scary with how good it was.
Serial - One multi-episode series at a time about complicated criminal cases.
What Roman Mars can Learn about Con Law - Started off during the Trump Presidency when tough questions about the US constitution are being asked given his penchant for pushing the legal boundaries and norms.
Paul interviews a different person each week and discuss their journeys on dealing with their mental health. Paul is also been very open about his struggles. It helps that he is a comedian and has a subtle but dark humor that I enjoy.
I also really like the short surveys that he reads and people have filled out on his website because they make me feel connected that I’m not alone.
Behind the Bastards, a deep dive into the various shit people of history. Episode one is Saddam Hussein: Erotic Novelist.
There's nearly 700 episodes, and I've yet to run tio a dud. Loads of great guests. My only gripe is that it's a touch Amerocentric, but other than that I'd recommend it to basically anyone. Not kid friendly, in case that wasn't obvious.
Hello Internet - I love the hosts, though the show is over (or, on hiatus if you truly believe)
Cortex- I listen to this mostly because CGP Grey is on it (who also was one of the hosts on Hello Internet). It's also nice for tech news/ productivity information, though sometimes I get a bit frustrated at the show
Dear Hank and John (or Dear John and Hank) - John and Hank Green answer listener questions. I'm really a sucker for this "two guys talk at the mic" format lmao
Dungeons and Daddies- a DnD podcast with Freddie Wong that I find immensely entertaining
Well There's Your Problem - an engineering disasters podcast. I really enjoy listening to the hosts, though they do tend to ramble. I like it, but might not be for everyone
Edit: Almost forgot, Wizards of Waverly Place Podcast. David Deloise and Jen Stone (The dad and Harper from the show) watch old Wizards of Waverly Place episodes and talks about them as well as has guests from the show on. This one can get a bit frustrating for me as the podcast feels a bit rushed, and their social media presence is very click baity. But I find it interesting none the less
I dig My Brother, My Brother, and Me from time to time. It's just three nerdy brothers dorking out together. They used to answer Yahoo questions but they moved to wiki how's since Yahoo died. They good for a laugh but even I admit they can be a handful sometimes lol
Obviously it depends on what you're into but I love tech and gaming. I listen to the wan show, friends per second, trash taste and the waveform podcasts.
