Google is changing the results displayed by its search engine to include data from its social network, such as photos or blog posts made by Google+ users, as well as the public Internet. Although data from a user’s Google+ contacts is not displayed publicly, Google’s changes make the personal data of users more accessible. Users can opt out of seeing personalized search results, but cannot opt out of having their information found through Google search. Also, Google's changes come at a time when the company is facing increased scrutiny over whether it distorts search results by giving preference to its own content. Recently, the Senate held a hearing on Google's use of its dominance in the search market to suppress competition, and EPIC urged the Federal Trade Commission to investigate Google's use of Youtube search rankings to give preferential treatment to its own video content over non-Google content. Google has also acknowledged that the FTC is investigating whether Google uses its dominance in the search field to inhibit competition in other areas.
