Google has acknowledged that the Federal Trade Commission has opened an investigation into the search company's business practices for possible antitrust violations. The investigation likely focuses on whether Google uses its dominance in the search field to inhibit competition in other areas. EPIC had previously opposed Google's acquisition of online advertiser Doubleclick, which was approved by the FTC over the objection of then Commissioner Pamela Harbor. EPIC later testified before the Senate Judiciary Antitrust Subcommittee on Google's growing dominance of essential Internet services.
