Sometimes, when acquiring a company, Google puts out multiple press releases and blog posts, sharing financial details and all other sorts of information.  Sometimes the search giant just mentions the purchase.  Today, though, Google had to disclose a few details for the sake of satisfying the SEC.

In its quarterly Form 10-Q report, Google acknowledged that it bought AdMob in May for $681 million and On2 Technologies in February for $123 million.  Then the company stated, "During the six months ended June 30, 2010, we also completed 20 other acquisitions for a total cash consideration of approximately $293 million."

That brings the year-to-date cost of Google’s acquisitions to $1.1 billion, which is an impressive number and doesn’t even include the $700 million ITA Software deal that hasn’t been approved (or Metaweb, for that matter).

Or, if you’d prefer to break things down a little further, Joseph Tartakoff looked at how much Google is spending on smaller deals, and wrote, "The company says it spent $148 million in cash to purchase 11 companies during the quarter, up slightly from the $145 million in cash it spent to purchase nine companies during the first quarter of the year."

Google’s doesn’t seem to have gone too crazy with its purchases, then, no matter how things may have appeared from time to time.  The company could have afforded to be much more aggressive, in fact, considering it’s managed to save up $30.1 billion.

Finally, while we’re on the subject of money, we’ll note that Google’s stock rose 1.15 percent today, which is a nice way to start the week.
