You can watch the gif animation play or click on the small graphics at the bottom to hone in on particular years.
If you liked our ten year recap, you'll love this. Each pie shows the revenue contribution from various formats, 1980-2010, based on RIAA revenue figures. If you want to see it again, just wait a few seconds for the animation to start over.
