It took the Windows Phone Marketplace 14 months to reach the 50,000-app mark, while Google needed 19 months to get the same result, and Apple managed to get to the figure in 12 months. Of course, the Google Android Market now has eight times more apps than the Windows Phone Marketplace and Apple’s App Store has more than a half-million apps, so Microsoft has a lot of catching up to do, even though you can find most of the big titles on any of the three platforms.
