Mobile advertising marketplace AdMob has revealed that it has served more than 5 billion targeted mobile ads since its launch in December 2006. The 5 billionth ad served was on 1 August for Electronic Arts NCAA Football game. The ad was seen on AdMob publisher CBS Sportslines mobile site by an AT&T subscriber using a Motorola RAZR v3.
The AdMob Marketplace has grown, the company says, with the addition of new mobile websites and new advertisers and the organic growth in usage of the mobile Internet. AdMob adds that it served over 1 billion ads in July alone.   
AdMob provides a monetisation model for mobile websites, serving targeted banners and text ads using mobile-specific parameters, as well as contextual and demographic information. The AdMob Marketplace features more than 2,000 mobile websites and hundreds of brand and direct response advertisers. AdMobs ads are viewed by users in over 160 countries every day.
The company says the top markets by ads served are the US (45% of all impressions), followed by South Africa, the UK, India, Germany, Australia, and Israel. The top handsets used to access the ads are Nokia (33%), Motorola (14%), Samsung (12%), Sony Ericsson (12%), and Sanyo (5%).
AdMobs growth is a testament to the growth of the mobile Internet and proof that advertising business models are viable in mobile, says AdMob CEO Omar Hamoui. Mobile is a unique environment with new challenges and we are proud to work with our publishers and advertisers to unlock the enormous opportunity in mobile marketing.
