What's the difference between पिक्सार and डिज़्नी Sequels??

The main difference is probably that पिक्सार makes it's sequels but Walt डिज़्नी एनीमेशन doesn't except for The Rescuers Down Under. I believe that all of Pixar's sequels have been released theatrically while the only डिज़्नी sequel that was made द्वारा the main studio and is considered one of the 53 Walt डिज़्नी animated classics is The Rescuers Down Under. Melody from The Little Mermaid 2 for example, was probably not even considered for the lineup not only because of her age but because that film was not released theatrically या created द्वारा Walt डिज़्नी एनीमेशन Studios. I hope that made sense.
