Bank of America was the big mover, uprooting $600 million in marketing services dollars from 16 IPG shops and planting it at eight Omnicom agen-cies, chief among them BBDO. And although the shift was the product of a July-August review, sources said the seeds of the bank’s decision to look elsewhere were planted during bumpy contract negotiations in the first quarter and IPG’s falling out with account czar Bruce Nelson in June. Nelson was tight with client marketing chief Catherine Bessant, and his split with IPG was said to force BofA’s hand.
