It's impossible for me to just only select a few of them, so I have decided to select some based on a category/theme:

Podcast: Azeal. He makes VRChat podcast about ordinary individuals on any kind of topic. One of the most memorable (in a disturbing way) one was where a trans girl was literally abducted and used as a sex slave for several months. Another favorite where also a trans girl was forcibly put into a conversion camp by her parents.

Comedy: Casually Explained. He makes pretty informative introductions into subjects but done in a hilarious unique way. Another favorite one is Fitz. He has diverse and really funny friends, and they just joke around. His channel stands out in a way, that they make more edgier jokes than other channels. Also SsethTzeentach is amazing too.

Informational: HealthyGamerGG. It can be categorized as a podcast tbh, but he makes psychological videos, which are usually explained or catered to gamers. Kurzgesagt and OverSimplified are 2 great additional informational channels that I really like to listen to.

There are a bunch more channels that I love to watch, but that would make the list waaaay too long for the average viewer.

Ryan George of Pitch Meetings is great if you're sick of the formulaic, pandering Hollywood franchise movies.

Dave Borlace has an informative, although a bit dry channel on climate change and clean technology, Just have a think - There's a lot of unreported innovative stuff out there.

And finally, my favorite, Rollie Williams' Climate Town - The entertainment + information value of this channel is just unmatched. The creator is a comedian and has a degree in climate science and knows his shit of both worlds.

There are a ton of good content creators I follow, mostly in the edutainment field; I'll post three of them (the first three that came up in my mind) for the YouTube and Podcast category

YouTube:

• CGPGrey
• Kurzgesagt
• Veritasium

Podcasts:

• Hello Internet
• Writing Excuses
• If Books Could Kill

If you are going with Not Just Bikes, the there is a whole transit YouTube community you can see. Two of my tangentally favorites are as follows: Geoff Marshall does a lot of London/UK transit videos; his channel even has the series he did where he traveled to all UK train stations. Well There's Your Problem is a podcast with slides about engineering disasters that is also an engineering disaster itself; Episode 96 has Not Just Bikes on as a guest to discuss the travesty of bicycle design in the USA.

I also like Patrick H. Willems as a movie video essayist.
