Games rule. They represent 16 percent of the apps in the App Store, but 29 percent of the paid downloads. Entertainment also outperforms its presence in the store: 12 percent of available apps, but 22 percent of the paid downloads.
So those two pastime categories represent more than half the paid applications on the iPhone platform.
News applications — like the ones many of us rushed to build whereby we could scramble our venerable headlines and teasers into Yet Another Interface — represent 2 percent of the available apps but only 1 percent of the paid downloads. I suppose journalists can take some comfort, though, compared to other writers. Books make up 18 percent of available apps but only 3 percent of paid downloads.
