• Regions Represented: Africa, Asia Pacific, Europe, Middle East, North America, and South America

Representation
InMobi is committed to an independent and transparent leadership position in mobile advertising. With that in mind, the following
issues are present in this data.
Mobile Advertising Market Definition: This report covers mobile display advertising only including both WAP and APP. SMS/Text
and Search are NOT included in this synopsis.
Scale and Time In Market: Representation within the network is a function of the both scale and time in market. Readers can
expect more fluctation and variance in younger, smaller markets for the company.
Publisher Mix: As with any ad network, market representation is a function of the publisher mix. We have over 5,000 publishers
of all sizes and content types, but changes to the publisher mix in a given market could impact the data.
Advertiser Mix: Similar to publisher mix, the advertiser mix could impact the numbers in our network, although to a much lesser
extent than publishers.

3. ASIA
Asia Regional Profile: October 2010
Asia mobile ad impressions grew by just under 1
billion impressions in 90 days (+8.7%).
Smartphones primarily drove Asia impression growth on the InMobi
network, growing 47.2%. With mobile phone proliferation across
Asia, Smartphones increasingly become the primary digital media
screen for a large portion of the worldʼs population.
Smartphone gains (+719 million impressions) were
primarily driven by the Apple iPhone.
The Apple iPhone increased +6.5 share points in just 90 days. This
puts it as the clear number 1 handset in the region with over 1
billion impressions monthly. As iPhone penetration increases, we
can expect Apple to be the dominant smartphone OS in the region
and continue taking impression share from the historically Nokia
and Symbian OS region.
With 2.2 billion smartphone impressions, smart-
phones in Asia represent nearly 10% of the global
mobile ad ecosystem.
Android and iPhone OS are leading the push of smartphone
impressions in Asia, capturing +9.3 additional share points in the
region. This highlights a significant opportunity for advertisers to
reach consumers with engaging advertising experiences in emerg-
ing markets.
