Yahoo has just revealed just how many government requests for data it's received in the past six months, and it's beaten out Apple, Microsoft and Facebook. Marissa Mayer and General Counsel Ron Bell noted in a Tumblr post that the search giant received between 12,000 and 13,000 requests, "inclusive of criminal, Foreign Intelligence Surveillance Act (FISA), and other requests," between December 1st, 2012 and May 31st, 2013. According to Mayer and Bell, the majority of requests relate to "fraud, homicides, kidnappings, and other criminal investigations." Naturally, Yahoo notes that it can't specify how many FISA requests are in that figure due to their classified nature, but it "strongly urge(s) the federal government to reconsider its stance on this issue."Mayer and Co. also announced that their first "global law enforcement transparency report" will debut later in the summer, and will include data on the first half of 2013. It's not a one-time occurrence either -- the firm plans to update the dossier twice each year.
