Probably because he was the individual who bought the company from Lucasfilm to begin with?Originally Posted by cellarhound
Remember, Pixar used to be both a hardware and software division of Lucasfilm. When George put Pixar up on the auction block in 1986, Steve purchased both divisions, kept the software (which also meant he got to retain Lasseter) but ditched the hardware. (I used to work for the digital imaging company that bought the hardware division.) Pixar didn't go public until 1995.
Pixar is essentially just as much as "Steve's baby" as Apple is.
