Having risen from humble beginnings in the computer division at Lucasfilm, Pixar (owned by Disney since 2006) is now a Hollywood behemoth in its own right.
By pioneering computer-generated animation, the company has revolutionised cinema, notably with its Toy Story trilogy, which began in 1995 and concluded this summer, generating $5.5bn in takings along the way.
As chief creative officer, John Lasseter has overseen this success and must ensure that it continues. His secret? Not computer trickery, or shallow gimmickry, but good old-fashioned quality.
That, and knowing how to appeal to millions of children (and their parents) across the world.
