>Smiling Friends is still incredibly niche
For cartoon standards, it certainly isn't. It's incredibly rare for cartoons that don't feature a talking sponge or a wascally wabbit to break into the mainstream (in other words, it grabs normie attention). In the few years it's been out, it's managed to hit Family Guy/South Park levels of popularity, and it's definitely the most popular cartoon among kids/young adults. It receives daily free advertising from its fans, who call it the funniest shit they've ever seen. They'll write essays about how it defeats nihilism and it's bringing back edgy newgrounds/early aughts humor, despite it's organic dialogue and self-referential social media induced anecdotes.
Rick and Morty took like five or six years (not counting the long hiatus in between seasons 2 and 3) to be acknowledged by shows like Family Guy, or The Simpsons. Smiling Friends only needed three for that to happen.
