SAN MATEO, Calif. & LONDON – AdMob, the world’s largest mobile advertising platform, examines the geographic distribution of iPhone OS users in its June 2009 Mobile Metrics Report. AdMob’s latest report also uses this network data in combination with Apple disclosed figures to estimate the number of iPhone and iPod touch devices in various countries.

The report finds that worldwide adoption of Apple devices continues to grow. While North America leads with 58 percent of iPhone and iPod touch users, Western Europe and Asia have increasingly become popular geographic regions, representing 26 and seven percent of Apple device users, respectively. The worldwide ratio of iPhone to iPod touch users in the AdMob network was roughly two to one in June; although this varied from region to region, this ratio has remained relatively constant over the last several months, implying a similar growth rate for both devices worldwide.

Highlights from the June 2009 AdMob Mobile Metrics Report:

* 54 percent of iPhone and iPod touch users are in the United States
* Following the U.S., France, Germany and the UK each had more than five percent of all iPhone and iPod touch devices
* iPod touch users represent 38 percent of total iPhone OS devices in North America
* Requests from the Android OS increased 25 percent month over month. Android has five percent worldwide OS share and is slightly ahead of Windows Mobile for the first time

For the first time, AdMob’s June 2009 Mobile Metrics Report also features an estimated breakdown of the number of iPhone and iPod touch devices sold in various countries. Given Apple’s recent announcement that 45 million iPhone OS devices have been sold worldwide1, AdMob estimates that there have been 13 million iPhone and 12 million iPod touch units sold to date in the U.S. based on user data in AdMob’s network. Additional details and worldwide country estimates are listed in the feature section of the report.

This analysis is based on the 16.8 million unique users on iPhone and iPod touch devices on the more than 7,000 mobile sites and 2,500 applications in AdMob’s network in June 2009, the vast majority of which were free to download. Please see the notes section of the full report and the Metrics blog for more details on methodology.
