It appears that Google will be buying AdScape Media which delivers ads so that they can be viewed within video games. Google has already announced plans for brokering ads into newspapers and radio using the targeting capacity it has developed for search engine text advertising.
Google's moves into video games and other media could be viewed as a plan to fashion a larger footprint in the media buying market. But, its is also probably an unspoken acknowledgment that the Internet text advertising business is not longer growing as fast as it was a year ago.
Google's expansion may actually be masking a contraction.
