Google Scoops Up DoubleClick for $3.1 Billion

And the giant gets even bigger. Google has acquired DoubleClick. With this acquisition, Google obtains something it didn't have before: entry into the world of display advertising, the ad serving that goes along with that and the close relationships Double Click has with advertisers, publishers and agencies. That one phone call ad buy gets ever closer. Along with the deal, Google gets affiliate marketing company Performics, which DoubleClick recently acquired, further boosting Google's own recent launch of a CPA service.
