Featured: Android and iPhone Platform Unique Devices

Notes

• Apple noted last month that they have shipped over 85 million iPhone OS devices worldwide (50 million iPhones + 35 million iPod touch devices): http://techcrunch.com/2010/04/08/apple-has-sold-450000-ipads-50-

million-iphones-to-date/

• At its recent developer conference, Google announced that 100,000 Android devices are activated each day: http://gigaom.com/2010/05/24/android-vs-chrome-os/

• The data in this feature section is based on the number of unique devices, not ad requests. A unique device represents a device that has seen at least 1 ad request in the AdMob network in a given month.

Although Android has a notable presence in the US, the iPhone platform has a much larger global reach. The chart below examines the relative base of US and worldwide unique

devices on these two platforms in the AdMob network in April 2010. Please visit our blog for our thoughts on interpreting our unique user statistics: metrics.admob.com.

* In AdMob’s network there were 8.7 million unique Android OS devices and 10.7 million unique iPhones in the United States in April 2010. When non-phone devices running the

iPhone OS – the iPod touch and iPad – are included the number of unique devices jumps to 18.3 million in the US.

* In AdMob’s network there were 11.6 million unique Android OS devices and 27.4 million unique iPhones worldwide in April 2010. When non-phone devices running the iPhone OS –

the iPod touch and iPad – are included the number of unique devices jumps to 40.8 million worldwide.

AdMob Mobile Metrics ReportApril 2010

About AdMob

AdMob is one of the world's largest mobile advertising networks, serving billions of mobile banner and text ads a month across a wide range of leading mobile

Web sites and applications. AdMob helps advertisers connect with a relevant audience of consumers on mobile devices and gives publishers the ability to

effectively monetize their mobile traffic. Incorporated in April 2006, AdMob provides the tools, data, and business models fueling the explosive growth of mobile

media in more than 160 countries and territories worldwide.

About AdMob Mobile Metrics

AdMob serves ads for more than 23,000 mobile Web sites and applications around the world. AdMob stores and analyzes the data from every ad request,

impression, and click and uses this to optimize ad matching in its network. AdMob’s monthly report offers a snapshot of its data to provide insight into trends in

the mobile ecosystem.

Methodology

For every ad request AdMob analyzes information available in the user’s mobile browser. From this, AdMob determines device capabilities and more using

open source tools and a variety of proprietary techniques. The result is a snapshot of the devices viewing the more than 10 billion monthly ad requests and

impressions that flow through AdMob’s network. We believe this data will be valuable in identifying and tracking trends, evaluating market readiness and more.

AdMob also serves mobile ads into iPhone and Android applications. The traffic from these applications is included in the Metrics report.

There is no standard industry definition of a smartphone. AdMob's definition is based on Wikipedia: "A smartphone is a phone that runs complete operating

system software providing a standardized interface and platform for application developers" (http://en.wikipedia.org/wiki/Smartphone). AdMob classifies a phone

as a smartphone when it has an identifiable operating system and we continually update our list as new phones enter the market. Despite running the iPhone

OS, the iPod touch is not a phone, and thus not considered a smartphone based on this definition.

Limits of this Data

Representativeness - AdMob does not claim that this information will be necessarily representative of the mobile Web as a whole or of any particular country-

market. AdMob’s traffic is driven by publisher relationships and may be influenced accordingly. Because the data is pulled across ads served on more than

23,000 sites and applications, we feel the data will be useful and may help inform business decision making.

Ad Request Classification - For some handsets and operator networks, it is difficult to collect full handset data. AdMob categorizes these requests as

"unclassified" and does not serve targeted ads to these requests.
