Two regulators cleared Google-DoubleClick on competition grounds only

The revenue mechanism

Google completed its acquisition of DoubleClick on 11 March 2008, according to Google's own securities filing reporting the deal's completion. Google and DoubleClick's then-owner, Click Holding Corp., had signed a merger agreement on 13 April 2007 valuing the deal at a base calculation amount of 3.11 billion dollars, a figure Google's filing on that agreement states directly; the completion filing later put the actual cash paid at approximately 3.24 billion dollars once adjustments for DoubleClick's cash and expenses were applied. The deal combined Google's advertiser-facing AdWords and publisher-facing AdSense businesses with DoubleClick's ad-serving and management technology, folding publisher ad serving and an emerging advertising exchange business under one owner rather than leaving them split between rival technology providers.

What the documents show

Google's completion filing confirms the 11 March 2008 close and the roughly 3.24 billion dollar final payment. The US Federal Trade Commission's own 20 December 2007 statement says it closed its eight-month investigation on a 4-1 vote, concluding the acquisition was unlikely to substantially lessen competition, while separately stating that consumer-privacy concerns raised about the deal were not unique to Google and DoubleClick and that the FTC lacked authority to impose conditions unrelated to antitrust. The European Commission's clearance decision, dated 11 March 2008, similarly found the deal unlikely to significantly impede competition in the European Economic Area following an in-depth investigation opened in November 2007, and cleared it without behavioral conditions.

The assumptions exposed

Both regulators cleared the merger on antitrust grounds specifically; neither document states a finding that the combination was harmless in every respect, and the FTC's own statement is explicit that it can only weigh competition effects, not privacy concerns, under the law it was applying. A reader should not read either clearance as a privacy determination, since both agencies say so themselves. The two headline dollar figures, 3.11 billion at signing and 3.24 billion at closing, describe the same deal at different stages and are not competing or inconsistent numbers; the difference reflects the contractual adjustment mechanism Google's own filings describe.

What to check before you rely on it

This is an editorial checklist for citing this deal as a precedent in later ad-tech antitrust discussion.

• Is a cited deal value the announcement-stage figure or the completion-stage figure, and is the source clear about which?
• Does a source claim the FTC or EC cleared privacy practices, when both regulators state they assessed competition only?
• Does the source separate this 2007-2008 clearance from later, distinct ad-tech antitrust rulings rather than treating them as one continuous case?

The lasting mechanism worth tracking is structural: two regulators independently reviewed the same combination of ad-serving and ad-buying technology under one owner and cleared it on competition grounds in 2008, a decision later ad-tech antitrust proceedings would revisit under different facts and different legal theories.
