How history/tech YouTube channel Asianometry reached 270K subscribers, $5K/month
5 years and 300+ well researched videos results in $5k/mo revenue, mostly patreon. This shows how brutally unforgiving the youtube economy is, even when your content is excellent. I fully expect this channel to grow to $50k/mo in the next couple of years, but still, the stamina required to get there amazes me.
