Ad spending on Facebook will reach $4.05 billion worldwide in 2011--more than double last year's figure of $1.86 billion in global ad revenues, according to a new estimate by eMarketer. By 2012,
worldwide ad spending on Facebook is expected to reach $5.74 billion, up 42% over 2011.
"2010 was the year that Facebook firmly established itself as a major force, not only in social
network advertising, but all of online advertising," said eMarketer principal analyst Debra Aho Williamson, in an article released today. "In 2011, its global presence is something multinational
advertisers can't ignore."
By contrast, eMarketer predicts ad revenues at former Facebook rival MySpace will fall to $184 million in 2011, down from $288 million in 2010 and $470 million in
2009. Spending on social media advertising overall in the U.S. will increase 55% to $3 billion this year, with social media accounting for 10.8% of all online ad dollars. Read more here.
