>>11150421For the west, it's unironically weebs who got addicted to watch CGDCT in the form of livestreams.
There are a handful of Nijis that have a similar vibe to Holos, but in terms of "anime girls making cute noises", Hololive holds the monopoly for that. Intra-company collabs meant if you watched a Korone clip, you'll be introduced to Okayu or Fubuki soon.
It's a meme that when people first stumble upon this video, they don't know 80% of the holomems. Then 2 weeks later, you know everyone and are subbed to half of them.

Someone like Kuzuha saying nigga wouldn't be as funny as Miko.
That's at least how Hololive got started in the west.
Gura is an inexplicable phenomenon that I think marketing analysts will be studying for years and failing to replicate.
