Facebook expansion in mobile ads business is now a serious threat to Google, the dominant player in the field. According to IDC, the mobile display advertising market in the U.S. expanded by 88% in 2012 to $4.5 billion, after posting a 125% growth in 2011 and projects a growth rate of 55% to 65% in 2013, as spending reaches roughly $7 billion in the U.S. Despite the considerable slow growth in mobile search, Google has remained dominant in search advertising with a stake of two third of the market, but the serious threat is coming from Facebook, the new leader in dominating the mobile display advertising market. From social media to politics projects, Facebook is raising capitals to dominate the scene. Will the future political and presidential campaign starts from Facebook?
