In response to a FOIA request filed by EPIC, the Federal Trade Commission has stated that there are no records of "communications . . . between the White House and the FTC regarding the Commission's antitrust inquiry into Google." In a closely watched proceeding, the Federal Trade Commission announced in early January that it had closed an antitrust inquiry into Google's business practices. EPIC has previously expressed concern about anticompetitive practices by Internet firms. In 2000, EPIC filed a complaint with the Federal TradeCommission regarding the proposed merger of Doubleclick, an Internet advertising company and Abacus, a catalog database firm. In 2007, EPIC opposed Google's acquisition of DoubleClick, which was approved by the FTC over the objection of former FTC Commissioner Pamela Harbor. In 2011, EPIC wrote to the FTC about Google's use of YouTube search rankings to give preferential treatment to its proprietary content over non-Google content. EPIC has also testified before the Senate Judiciary Committee regarding growing market concentration of essential Internet services.
