The New York Times does it again with
a great web-based interactive graph of movie box office takes since 1986. It is adjusted for inflation so you can concentrate on how much more movies take in now compared to just 10 or 15 years ago. You can also see that it all comes in bursts now.. when Top Gun came out, it was making box office monies from May through December of 1986.. National Book of Secrets has already trickled to nothing in less than 3 months.
