iTunes Music Store downloads graphed

Dur.

That's what I get for posting before my first cup of coffee.

john, there's nothing misleading about this graph. You can easily follow how many songs have been sold at any given time by using simple arithmetics. Let me help you: at first, it took 30 weeks to reach 25 million downloads, during the next 30 weeks the number went up to 100 million, that is 75 million new downloads (3-fold increase compared to the previous 30 weeks). In the next 30 weeks they sold 150 million songs (2-fold increase), and then 250 million (1.7-fold), and then more than 500 million (+2-fold). In conclusion: sales have been roughly doubling every 30 weeks. Ever heard of exponential growth?

BTW, I predict that we're gonna see a prettier version of this chart sometime tomorrow...

This chart is rising somewhat exponentially! Eventually, everyone on the planet could conceiveably have downloaded every song available now and in the future of the iTunes music/video/etc/ store, and there would be absolutely NOTHING TO DO!!!

Err.

Implicit in that chart is that sales are _cumulative_, so that growth is slightly misleading (read: of course it's just going to keep going up and up).

What would be more useful to see is a chart of the number of songs sold per week. Wonder how much that's changed over time?

Cha-ching! As a stock holder you gotta love that..great post!
