The search giant revealed the number via a regulatory filing.
Google's largest acquisition this year has been the massive $861 million purchase of mobile advertising company AdMob, which was easily integrated into Android.
The company also purchased social gaming company Slide for $180 million and video software developer On2 for $123 million.
That $1.6 billion figure could jump substantially if Google's proposed $700 million acquisition of airline travel software company ITA Software is completed. The purchase is pending as EU and U.S. anti-monopoly regulators look at it.
Google still has $33 billion in cash.
