They went pretty hard on kpop music side - grinding Melon charts etc. IIRC they got Billboard weekly top 3 for South Korea some time ago.
When they started, they did public
public auditions on VRChat, idol talent competition style
a la Produce 101, at a time when that style of reality TV was still arguably peaking.
Korean Pewdiepie drove the whole thing and later signed them, so there's no fumbling around learning how to market streamers.
Getting serious sponsors - LG, Lego, Nvidia, AMD, Naver etc. looks really good.
Also after Korea cut off Twitch earlier this year, that entire side of "online entertainment" is insanely well-contained to Afreeca (now renamed SOOP).
I think it's quite a different thing from "vtubing" as we understand it and I don't think it's replicable in any other market.
Very few people on this forum would be interested in how they do things.
No EOPs and no yabs, just two completely unrelated facts btw.
Maybe Koreans are so desensitized to being parasocial with kpop idols that vtubers/streamers seem relatively distant lmao.
Look into PLAVE if you guys want to experience being oddly impressed by highly skilled dudes but it doing nothing for you since you're heterosexual.
