2. ABOUT THE RESEARCH
Project Background
After launching in 2007 in Asia, InMobi quickly grew to become the world's largest independent
mobile advertising network. In the second quarter of 2011, we served 104.9 billion impressions in
165 markets worldwide. With a physical presence in 5 continents, over 5,000 publisher partners,
and a broad, independent market footprint, InMobi is well positioned to provide an objective,
comprehensive, and representative view of the mobile advertising market.
Research Objectives
We have three goals with this research:
1. Help educate the market. Statistics and information about the state of mobile
advertising are lacking in most regions of the world.
2. Track consumer opinions regarding mobile advertising. With any emerging
medium, the consumer perspective is critical to overall market success. We see
a need for trending across regions in this area.
3. Collaborate with industry thought leaders to increase market insight and improve
information quality ongoing. As a global independent company, we value
partnerships that will strengthen our understanding of the market. Researchers,
thought-leaders, and analysts are encouraged to contact us and apply for full
partner access.
Beginning July 2011, InMobi is moving towards
Contact Information quarterly data views which will highlight broader

3. NETWORK DATA
Specifications
Data in this report are sourced from our global mobile advertising network which served 104.9 billion
impressions in the second quarter of 2011. With 165 countries receiving over 1 million impressions
monthly, we are able to claim one of the broadest and most representative networks in the world. Exact
specifications are as follows:
• Global Available Impressions in Quarter 2, 2011: 104.9 billion
• Regions Represented: Africa, Asia Pacific, Europe, Middle East, North America, and South America
• Countries Represented: 114 countries with over 10 million impressions per month
• Base Measure: Available Impressions
• Reports: Market Summary, Manufacturer Share, OS Share, and Top Handsets & Connected Devices
• Time Periods: Q1 2011 (January – March 2011), Q2 2011 (April – June 2011)
• Comparisons: Q2 2011 versus Q1 2011
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 fluctuation 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.
