Social media advertising revenues are forecast to reach $8.3 billion in 2015, up from an estimated $2.1 billion in 2010—a compound annual growth rate (CAGR) of 31.6%, according to BIA/Kelsey's US Local Media Annual Forecast.
Display, which dominates social media advertising* is projected to climb from $2.1 billion in 2010 to $7.7 billion in 2015—a CAGR of 30.4%.
Though revenues for non-display ad formats, such as Twitter's "promoted products," are now minimal, the category is expected to expand, from zero in 2010, to $600 million in 2015, at a 65% CAGR.
Facebook is expected to dominate social advertising over the next five years.
"It's no surprise that Facebook commands a dominant share of all social ad impressions served and ad revenues generated," said Jed Williams, analyst and program director of BIA/Kelsey's Social Local Media practice. "As the social market leader, it already serves the most display ad impressions of any digital company, surpassing both Yahoo and Google.
"We fully expect Facebook to increase both impression share and ad revenue, as buyer awareness accelerates and creative formatting and targeting improve to optimize performance."
Google is projected to account for 16.7% of display ad revenues in 2012, followed by Yahoo with 16.4% and AOL with 3.7%.
