Two interesting compare and contrast graphics here from Italian social media researcher Vincenzo Cosenza. The first shows the state of the world in terms of social networking sites in December 2009 and the second shows the position in December 2012. Never mind the numbers of users, the 2012 graphic reveals how FaceBook has obliterated the competition to become the largest social media platform in 127 of the 137 countries surveyed. The only places where FaceBook does not now predominate is in Russia/CIS plus China PRC and Iran.
