Steve Jobs wasn't always an Apple employee.

In 1985, the young entrepreneur was forced out of the company he founded, due to reasons such as low sales and internal differences. The following year, Jobs bought The Graphics Group from George Lucas and Lucasfilm. The company was given a new name: Pixar.

Jobs would later return to Apple in 1997, while keeping his position at Pixar.

In 2005, Jobs spoke about his decade-long break from Apple.

The heaviness of being successful was replaced by the lightness of being a beginner again, less sure about everything. It freed me to enter one of the most creative periods of my life, he said during his 2005 commencement speech at Stanford University.

Since Jobs' acquisition, Pixar has produced 12 feature films, including Cars, Monsters, Inc., Toy Story and its sequels. The films have made a combined $6 billion at the box office worldwide.

In fact, Toy Story 3, released in 2010, is the highest grossing animated film of all time, with a worldwide gross of more than $1 billion.

On Wednesday night, Jobs died at the age of 56, surrounded by his family at his home in Palo Alto, Calif.

Steve Jobs was an extraordinary visionary, our very dear friend and the guiding light of the Pixar family. He saw the potential of what Pixar could be before the rest of us . . . Steve took a chance on us and believed in our crazy dream of making computer animated films . . . He will forever be a part of Pixar's DNA, Walt Disney and Pixar CCO John Lasseter and President Ed Catmull said in a statement.

Pixar's upcoming projects include Brave, featuring the voices of Emma Thompson and Julie Walters, and Monsters University, the sequel to the 2001 classic.
