AdDuplex has released some interesting statistics from a couple of days activity of almost 700 apps using the network's advertising service. Over the course of two days, the apps on the network were used in 189 countries, by 166,000 users. The U.S. (as expected) is leading the group with 34%, but should we look at data from just last month (chart below) you'll notice a slight change.
Countries that saw Windows Phone (and the Marketplace) being launched jumped up in usage percentage (India, Russia, etc.), which are positive signs of reach and let us not forget that this is data only on the AdDuplex network. Head on over to the AdDuplex blog to read up the full report (as well as see the breakdown of countries).
