Playing Whac-a-Mole With Piracy Sites; New York Times, 1/28/13

Ben Sisario and Tanzina Vega, New York Times; Playing Whac-a-Mole With Piracy Sites: "This month, the University of Southern California’s Annenberg Innovation Lab released a report that ranked 10 ad networks on the amount of business they do with sites suspected of engaging in piracy, with Google and Yahoo placing high on the list. Ad networks use advanced computer algorithms to place ads on Web sites. They can be run by agencies, publishers or others. The implicit criticism of the report is that the operators of these networks know which sites traffic in copyright infringement and therefore could keep ads — and ad money — away from them if they wanted to."
