According to eMarketer, Google's display advertising (in the U.S.) is expected to surge sharply, significantly outpacing second-place Facebook, Yahoo, and others.

Since acquiring DoubleClick in 2007, Google has concentrated its investments in display advertising. By 2010, Google surpassed Yahoo alongside Facebook, and is now nearly on par with Facebook. Google is expected to continue its rapid growth, approaching $6 billion by 2015 and significantly outpacing Facebook's $4 billion. Yahoo, Microsoft, and AOL are projected to remain flat.
