Where Pixar brought CGI into the theatre, Mainframe Studios brought CGI into television. Mainframe Studios, a Canadian corporation, produced Reboot and Transformers: Beast Wars, the first two ever CGI television shows. Even though animation like CGI was considered just for kids, both shows had elements in it that adults could enjoy as well. Beast Wars was quite famous for this, even creating episodes showing brutal character deaths on-screen, and having one particular episode built around a mentally-stunted character.
Reboot also had one of the very few villains who never suffered Adaption Decay throughout the entire series, instead growing more and more dangerous with each passing season (Megabyte FTW).
Sadly, Mainframe Studios declared bankruptcy a few years ago, so they aren’t developing any more shows. However, the shows they did develop are fantastic, and have actually become better over the years. (That’s my opinion and I’m sticking to it. 
)
Does anyone else remember Mainframe Studios?
