One small acquisition a month, Google chief Eric Schmidt projected last fall when announcing the internet giant was back on the hunt for privately owned firms after a short recession-induced break from buying.

“There may be larger acquisitions, but they really are unpredictable,” he told Reuters at the time.

Google has mostly stuck to its plan and even made of few of those riskier big buys. Since Schmidt’s revelations, the Web search giant has scooped up everything from small start-ups to much-larger industry rivals such as mobile advertising firm AdMob, a $750 million acquisition that many thought would land Google in an antitrust court battle. Indeed, the company has outpaced itself, buying more than just one firm a month in a few instances.

Schmidt and Co show no signs of letting up soon. On Thursday, Google announced plans to buy one of the Web’s largest providers of airline travel software, ITA, for $700 million, once again raising the specter of antitrust activity.
