There are now 100,000 mobile applications published on the Windows Phone 7 platform, according to a report. The market has been slowly growing over time since its launch, and has had trouble catching up with the Google Play and iOS App Store markets, but that may be changing. Historically, it took 14 months to reach 50,000 mobile applications, and only 5 months to double that to 100,000.
