Avatar and Gone with the Wind battle it out

Hi Friends,
Recent headlines trumpet "Avatar biggest money making movie yet" and I always wonder about such headlines. It turns out that headlines that say this are not correct and are very disingenuous.
My dh and I enjoy seeing movies in the theater on the big screen and give a high rating to our most recent film viewed, Sherlock Holmes.
We haven't seen Avatar yet, and aim to, soon.
I saw this fun link http://boxofficemojo.com/alltime/adjusted.htm
The link shows movie gross earnings adjusted for inflation. The key here is "adjusted for inflation"!
Using this benchmark, the experts there determined that Avatar is no. 26 for earnings, thus far. Numero uno is Gone with the Wind, followed by Star Wars, Sound of Music, and more, and you can read the ratings by following the link.
What impresses me is that there are more than six billion people on earth now,  vs. perhaps one billion when Gone With the Wind was released, and today there are so many more theaters and abundant technology, yet Gone With the Wind has not been toppled from its rank, at least not yet.
