How Free Took Over the AppStore
How free took over the app store, via GamesBrief:
In June 2010, 71% of the worldwide 100 top grossing apps on the App Store were paid only. Just two years later, that figure is 16%.
If we include apps that are paid but also enable in-app purchases (IAP), the figure falls from 93% to 32%.
When you go digital, and a de facto cartel doesn’t block a zero price (as is happening in the book industry), the price trends to free.
