The Biggest Money Making Movies

I enjoy following box office stats and am looking forward to seeing if The Avengers will be able to overtake Avatar as the biggest money maker in movie history.

As I've compared movies, I've noticed that of the 250 biggest money makers, most of them have been released in the last 20 years. I'm sure part of this is due to inflation, but I think another factor is a result of how many movies are released these days. Below I list the top 5 domestic money earners by decade.
