The 2011 forecast for online ad spending in the United States is $1 billion higher than eMarketer’s last estimate of US social network ad spending, made in August 2010.
The primary driver of the change in projected spending is greater ad spending on – you guessed it – Facebook, the company says.
eMarketer predicts ad spending on Facebook will rise to $2.19 billion in the United States this year, and just over $4 billion worldwide – both more than double last year’s figure.
As we mentioned yesterday as well, eMarketer expects ad revenues at once-rival Myspace to drop to a lousy $184 million in 2011, down from $288 million in 2010 and $470 million in 2009.
