Madison Avenue's revenge: New ad boss is AOL's seventh since 2001When new AOL ad boss Lynda Clarizio replaced Curt Viebranz, his head was the sixth to roll at AOL since 2001. Viebranz followed Myer Berlow, Robert Friedman, Robert Sherman, Lisa Brown and Michael Kelly. Three lasted less than a year. None of them succeeded, according to Bits, because AOL's reputation on Madison Avenue remains tattered from the pre-merger days when Berlow and former AOL CEO Bob Pittman would spurn agencies to work directly with marketers, locking them into long-term deals at inflated prices. Take heed, Google's Tim Armstrong. (Photo by macloo)
