MORE THAN 1.5 BILLION APPS HAVE BEEN DOWNLOADED FROM APPLE'S APP STORE, the company said this week. iPhone and iPod Touch users have racked up the downloads in just a year, with the store now holding over 65,000 applications (though that figure has been questioned by some, as it's inflated by so-called "bulk apps"). Source Meanwhile, GetJar, which runs an independent, multi-platform app download site, says it, too, has seen more than 1.5 billion downloads of the 50,000 apps it carries. It says the five most popular apps are Opera Mini; three mobile social networking apps, eBuddy, Nimbuzz and mig33; and Google Maps. Source The Bottom Line: The attraction of app downloads rolls on, and not just for iPhone users. One question, though: how many of those 1.5 billion apps on iPhones get actively used? Still, in some sense, it's not that important. The big download figures show what mobile users will do when the browsing, download and installation process is quick and simple - something that can't be said about many previous attempts at app stores on other platforms. *** INSIGHTS ON MOBILE DATA USAGE. Peggy has passed over some stats from Comscore from the Open Mobile Summit, a top-notch conference and networking opportunity that MSearchGroove is proud to sponsor as a media partner. In fact, MSG will be a sponsor and speaker at the next Open Mobile Summit in November in San Francisco - but more about that later. The figures show some interesting points about mobile media usage, including that a higher percentage of US mobile users are mobile media users (meaning they use browsers or apps, or download media) than Europeans, at 35 percent to 28 percent.
