Global Social Media Ad Revenues Grow 60% Year-Over-Year

Global social media revenues will increase from $11.8 billion in 2011 to $16.9 billion in 2012 – that’s a 43% increase – according to a new report from Gartner.  By 2016, social media revenues will increase to $34 billion, with advertising the biggest contributor by far.

Social media ad revenue will increase from $5.5 billion in 2011 to $8.8 billion in 2012, a year-over-year growth rate of 60%.  According to the Gartner forecast, advertising’s share of global social media revenues will increase from 46.6% to 52%.

Social gaming is the other major source of revenue for social media, totaling $6.2 billion in 2012, or 36.7% of total social media revenues.  Social gaming revenue more than doubled between 2010 and 2011, with the sale of virtual goods largely responsible for the revenue in this area.

Gartner is not the first to adjust social media revenue forecasts upward, according to MediaPost.  How have the numbers changed?  Gartner predicted last year that total social media revenues in 2011 would equal $10.3 billion, but the latest analysis has revised that number to $11.8 billion.  For 2012, Gartner’s prediction has grown from $14.9 billion to the current estimate of $16.9 billion.
