The Interactive Advertising Bureau earlier this year estimated U.S. mobile ad spending at $1.6 billion in 2011. Looking beyond U.S. borders, the IAB issued a new report estimating the global mobile advertising market at $5.3 billion, with a wide gap between developed and emerging regions.
Asia-Pacific, for example, represented 35.9% of worldwide mobile ad spend, North America, 31.4%, and Europe, 25.9%. That compares to Latin America, with just 3.5%, and the Middle East and Africa, at 3.2%. The study, conducted by the IAB’s Mobile Marketing Center of Excellence in the U.S., IAB Europe and research firm IHS Screen Digest, also broke out mobile advertising for each region by type: display, search and messaging. Across the board, search accounted for the largest share of mobile ad spending, typically at least double the amount of display for a given area. In North America, spending was more balanced, with search contributing $811 million, display hit $572 million and text message advertising, $295 million for a total of $1.68 billion.
