eMarketer has revised its revenue forecast for Facebook in light of the company’s recent IPO filing showing slower growth than the research firm had projected. It now expects Facebook global sales to grow 64% to $6.1 billion this year, up from $3.7 billion in 2011. The firm had previously estimated its 2011 revenue at $4.3 billion.

eMarketer also predicts that the social network’s share of all U.S. display ad revenue will grow to 16.8% in 2012 from 14% last year. Close on its heels will be Google, claiming 16.5% of the display ad market, up from 13.8% in 2011. The two companies combined will account for a third of all display ad spending in 2012.

As the total U.S. advertising market rises to $169.5 billion in 2012 from $158.9 billion in 2011, the firm estimates that approximately one in 10 advertising dollars spent will go to Google.
