Google's Acquisition of DoubleClick: FTC Monopoly Review
This paper examines the Federal Trade Commission's 2007 investigation of Google's acquisition of DoubleClick under the Clayton Act. It explores whether the merger substantially lessened competition in the online advertising market or tended to create a monopoly. The paper reviews the FTC's findings that Google's AdWords business and DoubleClick's ad-serving functions did not substantially overlap, the diversity of the online advertising marketplace, and the presence of competing third-party ad servers. It also addresses the dissenting minority's concerns about vertical competition issues, privacy implications, and the difficulty regulators face in keeping pace with rapidly evolving digital advertising technology.

What makes this paper effective
- Grounds its analysis in a specific statutory framework — the Clayton Act — giving the argument a clear legal anchor rather than relying on vague claims about corporate size.
- Balances the majority FTC ruling with the minority dissent, presenting both sides of the regulatory debate without overstating either position.
- Integrates direct quotations from primary FTC documents effectively, allowing official language to carry evidentiary weight.
Key academic technique demonstrated
The paper demonstrates how to use primary regulatory documents (FTC statements, case filings) as principal evidence in a policy analysis argument. Rather than relying solely on secondary commentary, the author anchors each major claim to an official source, which strengthens credibility and keeps the analysis tethered to the actual regulatory record.
Structure breakdown
The paper opens by establishing Google's market dominance and explaining how DoubleClick fits into its advertising ecosystem. It then introduces the legal standard under the Clayton Act before walking through the FTC's majority findings. A fourth section addresses the dissenting commissioners' concerns about vertical competition and privacy. The paper closes by noting the broader regulatory challenge posed by fast-moving digital markets.
Introduction: Google, Advertising, and DoubleClick
The Internet search company Google dominates the search marketplace to the point that to "Google" something has become synonymous with searching for information online. However, maintaining its search engine is only one component of Google's business: to fund its activities, it must sell advertising. In addition to operating Google AdSense, Google acquired DoubleClick, which offered another venue for accumulating advertising revenue. AdSense and DoubleClick were subsequently conjoined: "an online publisher can set a DoubleClick cookie to tell them what sections of their sites you are browsing. DoubleClick will then judge the type of adverts you might like to see from what you're browsing…. If the cookie is set on a website that is part of AdSense and then you browse another site using AdSense, the same information will be recorded and pooled. Over time, guesses can be made about the interests of the person using that browser" (Geary, 2012).
According to its privacy policies, DoubleClick cannot match such information to personally identifiable information (Geary, 2012). Nevertheless, the merger raised significant concerns about monopolistic competition in the online advertising market.
FTC Investigation Under the Clayton Act
In 2007, the Federal Trade Commission (FTC) used its statutory authority to investigate Google's acquisition of DoubleClick under the Clayton Act. The Clayton Act provides that the FTC may prohibit a merger if it is shown that it "may be substantially to lessen competition, or to tend to create a monopoly" (Statement of Federal Trade Commission Concerning Google/DoubleClick, 2007, p. 1).
The FTC's Findings on Market Overlap and Competition
Ultimately, the functions of DoubleClick were not found to overlap with Google's other operations to a substantial degree — including, notably, its sale of Google AdWords. The FTC observed: "Google, through its AdWords business, is the dominant provider of sponsored search advertising, and most of its online advertising revenue is generated by the sale of advertising space on its search engine results pages. DoubleClick does not sell sponsored search advertising. In fact, it does not currently sell any form of advertising" (Geary, 2012).
The FTC also noted that the market for online advertising is highly diverse. "The evidence shows that, as with other ads placed through ad intermediaries, most advertisers do not consider contextually targeted ads sold through ad intermediaries to be substitutes for directly purchased display ads. Not only are these forms of advertising sold through different channels, but they serve distinct purposes" (Statement of Federal Trade Commission Concerning Google/DoubleClick, 2007, p. 5).
Furthermore, in the third-party ad serving market there were a number of competitors — such as aQuantive and ValueClick — that offered functions similar to DoubleClick's but were not owned by Google (Statement of Federal Trade Commission Concerning Google/DoubleClick, 2007, p. 7). The presence of these alternatives supported the FTC majority's conclusion that the merger did not substantially foreclose competition.
Conclusion
The FTC ultimately cleared Google's acquisition of DoubleClick, finding insufficient evidence of substantial competitive harm under the Clayton Act standard. The majority concluded that the two companies' advertising functions were sufficiently distinct, that the broader online advertising marketplace remained competitive, and that existing rivals provided adequate alternatives to DoubleClick's services. Yet the dissenting commissioners' warnings about vertical competition and the pace of technological change highlight an enduring regulatory challenge: antitrust frameworks designed for traditional markets may struggle to anticipate the competitive consequences of mergers in rapidly evolving digital industries.
