The advertising experiment is over with Facebook: it works.
According to Bloomberg News' anonymous sources, agencies have figured out what sells on the social networking giant.
At a clip of $2 billion in revenue this year, FB has exceeded its internal estimates. They brought $700-$800M in the door last year.
FB has a 9.4 percent share of the US display advertising market -- stunning growth when compared to Yahoo (16.2%) and Google (6.7%).
And the money is flowing through Twitter, too, following its $3.7 billion valuation, Kara Swisher reports.
Twitter is in a re-make phase, as it builds its business -- and revenue -- models.
According to Business Insider: Kleiner is the only new investor in Twitter for the round. Previous investors in Twitter include Benchmark Capital, Union Square Ventures, Spark Capital and other angels and investors.
And Twitter has a blog post about the new dough?
