Eight members of Congress wrote to Google asking the company to explain the "steps [that] are being taken to ensure the protection of consumers' privacy rights." The letter follows Google's announcement that it would begin combining data gathered on consumers of over 60 Google products and services, including Gmail, Google+, Youtube, and the Android mobile operating system. The members' letter includes 11 specific questions ranging from the ways in which Google collects information to the specific consequences for Android phone users. In 2010, EPIC, along with other privacy groups, wrote a letter to Google about the company's decision to combine user data among 12 Google services. The groups warned that the practical effect would be to reduce privacy protection for users of Google services. For more information, see EPIC: In re: Google Buzz and EPIC: Google search.
