CHART OF THE DAY: These Five Companies Control 64% Of All Online Ad Spending
Interesting piece of data from digital marketing guy/VC Darren Herman: Just five companies control 64% of all online spending. (Incredibly, Google controls 46% of all online spending.)
One thing to note, says Herman: "With Facebook only now starting to monetize their platform, you can start to see how big an impact they could have on the dominance of the digital advertising landscape."
