Global mobile ad spending totaled $5.3 billion last year, according to a report by the Interactive Advertising Bureau's Mobile Marketing Center of Excellence in the U.S., IAB Europe and IHS Screen Digest, a London-based research firm. The report is the first initiative by the IAB to determine the size of the global mobile ad market.
The largest mobile ad market last year was the Asia-Pacific region ($1.9 billion), followed by North America ($1.7 billion) and Europe ($1.4 billion). Latin America and the Middle East and Africa each generated less than $200,000 in mobile ad revenue.
The report included mobile ad spending on digital, search and text messaging formats.
