Google has made yet another acquisition (this is number 20 in 2007), and it's one of the biggest yet.
On Monday, Google announced it was buying out anti-spam company, Postini. Widely used by corporations, Postini is one of the three large anti-spam players in the marketplace. Analysts believe this acquisition will strengthen the enterprise anti-spam capabilities to better compete with Microsoft.
Analysts estimate that Postini's revenue in the $40 - $50 million range, which suggests that Google paid a high premium with its $625 million cash offer.
Personally, I think this acquisition is less about fighting spam and more about bolstering Google’s suite of office applications designed to compete with Microsoft Office.
