For me it's DJ Peach Cobbler. I've been watching his videos since he had around 2,000 subscribers. Now it's nearly 450,000.
He used to mostly make videos on games, now he does a lot of history stuff too. He also has a little satirical news show, and a few tasteful shitposts. A really diverse YouTube channel.
What's your favorite YouTube channel that's not a mainstream big-name like pewdiepie, mrbeast, ksi, etc...?
Combo Class is a neat math education channel where things are often on fire or falling apart in the background in a way that’s fascinating on top of the math itself
Side note, I have no idea how many subscribers counts as obscure. It seems relative to the size of the niche. Or maybe I have no idea how big people are relative to how much I care about them. Like I would expect Ben Levin (music theory and production creator) to be closer in subs to Adam Neely (same) but he’s an entire order of magnitude lower. Like is CJ The X (video essayist) obscure enough at 341K subs?
