Walt Disney (NYSE: DIS) has a stunning record when it comes to acquisitions.The company paid $7.4 billion for Pixar, and $4 billion each for Marvel and LucasFilms. That $15.4 billion total seems steep until you consider what the Mouse House got for its money. With the three movie brands Disney can release roughly two Pixar movies, three Marvel films, and one Star Wars title each year, all with the potential to do $1 billion or more at the box office.Essentially, Disney bought itself hit-makers that it can exploit not only in movie theaters, but across TV, theme parks, and product licensing.
