If and when Goldman Sachs begins selling shares of Facebook, the banking and securities firm is almost guaranteed to have no trouble finding buyers.  Adding to the existing hype, a new report from eMarketer predicts that Facebook’s ad revenue will soar from $1.86 billion in 2010 to $4.05 billion this year.

The Dow didn’t get off to a great start this week; it’s been in the red for most of the day so far.  A new report predicts that the lingering effects of the recession will benefit the online advertising community, though, with U.S. marketers eventually spending $40.5 billion in 2014.

The years leading up to 2014 should be profitable ones, too.  As the graph below shows, eMarketer is of the belief that spending will be up 13.9 percent this year, and a 10.5 percent increase is supposed to occur next year.

U.S. advertisers will spend $1.68 billion on social networking sites such as Facebook, MySpace and Twitter in 2010, according to a new report from eMarketer.

The $1.68 billion figure represents a 20 percent increase over 2009 on social network advertising spending and is set to climb to more than  $2 billion in 2011.

Facebook’s raking in the money and crushing the competition, according to a new report from eMarketer.  eMarketer believes advertisers will pay Facebook $1.29 billion this year, which is about 3.7 times the amount it expects MySpace to receive.

You can read a Facebook-specific chart for yourself below.  As for its traditional rival, eMarketer said in a statement, "MySpace is diminishing in importance, with an expected $297 million in ad revenues worldwide next year, down 14% from $347 million this year."

The stock market crashed again today, with the Dow falling 2.49 percent and the Nasdaq losing an even more worrisome 3.01 percent.  But a new report predicts that lots of money will still be spent on ads in social games, with marketers pumping in bigger sums this year and in 2011.
