The folks at GigaOm have crafted a neat little infographic that lends insight into the scope and layout of the economy of Apple's App Store.
Using data from Flurry.com, Admob.com and Apple, the graphic shows that about 25 percent of the 134,000 apps by 27,000 developers are paid, the majority of which sell for $0.99.
According to the graphic, each App Store customer -- there are 56 million of them -- spends an average of about $10 per month on apps. That's 200 million apps counting for $500 million in revenues -- or, by my math, about $350 million for developers (average $13,000 per developer; but obviously many make none and a select few make tons) and $150 million for Apple...each month.
