Sure!
Bascially that graph is the top 25 selling products.
You take the top 25 DVDs and the top 25 BR movies and compare the salesranks among all movies. You can see that the top 25 DVD movies are pretty near the top 25 total movies. BRs top 25 products are at about the 60-75 area, so, as far as the top 25 movies at any given time, DVD outsells BR 3-1. Which is actually a very very good figure for BR seeing as how BR is usually 5-10$ more expensive.
Now, I know what you are thinking. "Well what about those products between 30 and 60-75, where are those?"
Other graphs on the site show the top 10, top 50, top 100, top 1000 and pricing.
The products from 1-60 are probably DVD movies, because otherwise BR would have been higher up in the previously posted graph.
Anyway, as you can see from the trends, if you look at all the graphs you see something like a scaled slope for BR, where the top 25 are really high up, the gap in the top 50 are farther apart, and so on. What this means is that BR simply does not have as many movies on the market as DVD. As more and more movies are released, and more and more people invest in BR technology, you will see each graph getting tighter and tighter until they switch positions and DVD starts falling as companies make fewer and fewer DVDs.
Hope that was helpful :)
