What's the first animated movie to be nominated for Best Picture?

Saturday mornings were sacred. A bowl of cereal in hand, I'd plant myself in front of the TV, ready for hours of animated mayhem. Pure bliss.

Meanwhile, in the gilded towers of Hollywood, executives scoffed at the mere idea of cartoons competing for cinema's top prize. "Best Picture? For glorified doodles? Pshaw!" they'd sneer.

But times change, even for the most stubborn of industries. Slowly but surely, those hand-drawn (and later, pixel-perfect) worlds started to chip away at the Academy's marble facade. All it took was a dash of imagination and a boatload of heart to prove that animation could pack as much emotional punch as any live-action drama.

So, which animated film made history by becoming the first to be nominated for the Academy Award for Best Picture?
