Google’s AdMob Acquisition a Done Deal

Federal regulators on Friday approved Google’s $750 million purchase of mobile advertising company AdMob. Now, less than a week later, the search sovereign has closed the deal.

“We believe that mobile advertising can play a significant role in every single marketing campaign. We’re passionate about the unlimited possibilities in this space,” Susan Wojcicki, Google vice president of product management, said in a celebratory blog post. “Today, with AdMob, our work to make them a reality begins.”

And what a circuitous route it was to get there. Google (GOOG) announced plans to buy AdMob last fall, but the acquisition was quickly hamstrung by a grueling regulatory review.
