Yes, I know, but the 2000s was internet boom. The internet in the 90s was rather boring; in Japan, it was primarily limited to Yahoo and websites found in magazines. The 00s marked the beginning of streaming services. many of the vtuber hags like Canan and Mikeneko they started creating content around that time.
Little fun fact about that. Brazil has the largest japanese population out of Japan. Older generations used the term "panettone woman", which is pretty much the same - panettone gets cheaper after december 25th, and brazilians consume it essentially the same way japanese do with their christmas cakes. Nowdays it's pretty much rural southwest and south slang, but it's kinda funny how they brought it to our culture lol
