(FILES) – A picture taken on September 24, 2009 in Paris shows the screen of a computer featuring the home page of Internet giant Google’s website. Two consumer groups urged the US Federal Trade Commission (FTC) on December 28, 2009 to block Internet search and advertising giant Google’s proposed purchase of mobile advertising company AdMob. In a joint letter, Consumer Watchdog and the Center for Digital Democracy (CDD) asked the FTC to oppose Google’s acquisition of AdMob on anti-trust grounds and said the deal also raises privacy concerns.
