LucasArts was originally started in 1982 as the Lucasfilm Games Group, part of the Lucasfilm Computer Division (a division that was started in 1979 when George Lucas wanted to branch out into computers). The Lucasfilm Games Group became known as Lucasfilm Games when it began releasing games in 1984.  The Lucasfilm Graphics Group was sold to Steve Jobs in 1986, and became known as Pixar. What remained of the Lucasfilm Computer Division was retained as part of Industrial Light and Magic.

In 1990, Lucasfilm Games was consolidated into LucasArts.
