This past week, the US Federal Trade Commission gave the green light to the merger of Google and DoubleClick. As is highlighted in the official Google blog entry on the topic, privacy didn't play any part in the FTC's decision:
Official Google Blog: Analysis: The FTC clears our acquisition of DoubleClick
Privacy not a part of the merger review. Though we strongly believe in protecting our users' privacy, the FTC clearance decision reaffirmed the law by noting that privacy concerns played no role in its merger review. This is an important principle, as privacy issues need to be addressed on an industry-wide basis, and not on a company-by-company basis. The FTC wrote, "although such issues may present important policy questions for the Nation, the sole purpose of federal antitrust review of mergers and acquisitions is to identify and remedy transactions that harm competition. Not only does the Commission lack legal authority to require conditions to this merger that do not relate to antitrust, regulating the privacy requirements of just one company could itself pose a serious detriment to competition in this vast and rapidly evolving industry." The FTC also noted, however, "that the evidence does not support a conclusion" that this particular transaction will harm consumer privacy.
Data combination wouldn't pose problems. The FTC rejected the suggestion from competitors that Google would combine user information with DoubleClick's customers' data to obtain an advantage in the market, writing that the data is owned by DoubleClick’s customers and that "at bottom, the concerns raised by Google’s competitors regarding the integration of these two data sets -- should privacy concerns not prevent such integration -- really amount to a fear that the transaction will lead to Google offering a superior product to its customers." Moreover, "a number of Google’s competitors have at their disposal valuable stores of data not available to Google. For instance, Google’s most significant competitors in the ad intermediation market, Microsoft, Yahoo!, and Time Warner have access to their own unique data stores."
