New York State Attorney General Letitia James announced Tuesday that 47 attorneys general from states and U.S. territories plan to take part in a New York-led antitrust probe into Facebook. Shares of Facebook fell as much as 2.2% on the news. From a report: The multistate investigation was first announced in September with participation from seven other states, but it has since expanded considerably. The probe will zero in on Facebook's dominance in the social media industry and whether it broke any state or federal laws as a result of any anticompetitive conduct related to that dominance. "After continued bipartisan conversations with attorneys general from around the country, today I am announcing that we have vastly expanded the list of states, districts, and territories investigating Facebook for potential antitrust violations," James said in a statement. "Our investigation now has the support of 47 attorneys general from around the nation, who are all concerned that Facebook may have put consumer data at risk, reduced the quality of consumers' choices, and increased the price of advertising. As we continue our investigation, we will use every investigative tool at our disposal to determine whether Facebook's actions stifled competition and put users at risk." It comes as Facebook already faces a separate antitrust investigation launched by the Federal Trade Commission in July.Read more of this story at Slashdot. Click here to read full news..
