According to a recent report by Gartner, global revenues from social media are set to grow 43.1% in 2012 and reach $16.9 billion. Advertising leads the surge with $8.8 billion, followed by social gaming contributing $6.2 billion. Subscriptions are the third most successful, accounting for $278 million. What is interesting about these figures is that the U.S. commands around 53% of the revenues. While social media ad spend will continue to rise, overall growth rate will decline by 2014, but still remain higher than 10%.
