Google Inc is set to receive civil subpoenas from the U.S. Federal Trade Commission in preparation for an investigation into the Web giant's Internet search business, the Wall Street Journal reported on Thursday, citing people familiar with the matter.
The company, which dominates the U.S. and global markets for search advertising, has been accused by competitors of favoring its own services over rivals in its search results.
Google is already the subject of an investigation by European regulators on similar issues.
Google and the FTC declined to comment.
