Welcome to 3blue1brown! The main event is, of course, the YouTube channel. If you like what you see, it really is helpful for fans to subscribe. I think. Actually, I’ll level with you, I have no idea what a YouTube subscription means. If you like what you see please go give an impassioned rant to a friend about how wonderful math is.
Funding for 3blue1brown now comes primarily from viewers. Supporters have been a great source of early feedback on videos before their public release, especially while working on series. There are also several perks and benefits to members beyond early access, like store discounts, having your name in the credits, and more. Learn more →
If you want to ask questions, share interesting math, or discuss videos, take a look at the 3blue1brown subreddit. People have also shared projects they’re working on here, like their own videos, animations, and interactive lessons. When relevant, I often put these in video descriptions as added resources.
