Google has gobbled up restaurant review outfit Zagat, in their latest Pacman-like gobbling juggernaut. Since June 1st of this year, Google has acquired no fewer than PostRank, Admeld, SageTV, Punchd, Fridge, PittPatt, Dealmap, Motorola Mobility (if approved), Zave Networks, and, now, Zagat. In fact, Zagat will be Google’s 20th acquisition this year, and they still have three and a half months to go. And Zagat is the 102nd company acquired by Google in the past 8 years, with half of those acquisitions occuring in just the past two years!
