SO Coke has set the cat among the pigeons and shifted its Rs 50-crore ad account. I say 50 because that's the largest figure my poor brain can adjust to. One of the nicer side-effects of this will be hours of speculation in ad agencies and marketing departments across the land: Whose fault was it? How did Chaitra Leo Burnett swing it? Why didn't they call us? So where did McCann screw up?
