Acquired for: $7.4 Billion

Shortly after being ousted as CEO of Apple in 1985, Steve Jobs negotiated the purchase of George Lucas' digital animation studio. Renamed Pixar, the studio behind numerous digital blockbusters became Disney’s most valued asset heading into 2000. It all began with Toy Story in 1995 and Pixar’s managed to churn out several billion-dollar films for the mass media corporation ever since. Let's not forget the vast fortune made off of the films merchandising sales as well. The acquisition transformed Disney into an unstoppable marketing machine and one of the biggest major film studios in Hollywood.
