About the Data: The report describes its methodology as follows:
“Market size is gross, defined as after discounts, before agency commissions. Global market sizing and format split is based on reported data by local IABs, and a statistical and econometric model. Reported data has been harmonised to adjust for discounts and agency commissions. Modelled data is based on variables such as smartphone penetration, 3G subscriptions, messaging volume. The model has been refined based on benchmarking variables such as ad spend per capita, mobile subscriptions and 3G/4G penetration as well as through interviews with key players across the mobile advertising ecosystem. Model also takes into account typology of mobile ad markets in terms of maturity and format proliferation.
All data expressed in constant 2013 USD. Conversions into EUR based on 2013 USD-EUR foreign exchange rates.
