Sony as a media company is still too small, as a tech company it's still to small look at it's competitors.
Disney, Warner brothers, Naver, Kakao, Tencent, Netflix Sony is tiny, but it does play a big role in the animation industry. Including Kadokawa!
Crunchyroll (Sony subsidiary)
Bilibili
Hidive
Netflix
iQiyi
I don't know the korean & japanese sites. Anime is bigger than sony, (bandai namco, nintendo... etc)
