>>20742055During their inception it was revolutionary, the possibilities of a mocapped person was endless because of the fantastical stuff that can happen, which later devolved to the same as a regular youtube but with said mocapped person portraying an act, making them larger than life and therefore more interesting than a regular person.
Later thanks to a certain kombini worker it inspired a wave of indies who kept the concept but with a mix of avatars including L2D which went from the lowest budget to actually being more expressive than most full 3d models as we seen later on.
Eventually cooperates started to flood the market and (least from here) there was fears the market would be saturated, and while that has come to pass it just means there is a vtuber for everyone, which helps as now the english side and many other nationalities too, has become a streaming sub-genre.
So cut to now, basically regular streaming, but rather than no face cam voice only streams, there is an avatar, with lore to make for a nice segway into the streamer.
If you can't connect to a thot on screen you can simp for a big titty succubuss L2D even though irl it's either that thot you couldn't connect to/some dude/some chick with a great voice but looks ugly irl and some mental problems/someone who doesn't sound fitting for the avatar but they paid good money so deal with that.
TLDR alternative to on cam streaming these days
