AdMob is a mobile advertising company founded by Omar Hamoui. The name AdMob is a portmanteau for "advertising on mobile". It was incorporated in 2006 and is based in San Mateo, California. In November 2009 it was acquired by Google for $750 million. The acquisition was completed on May 27, 2010. Apple Inc. had also expressed interest in purchasing the company the same year, but they were out-bid by Google. Prior to being acquired by Google, AdMob acquired the company AdWhirl, formerly Adrollo, which is a platform for developing advertisements in iPhone applications.
