THE ESSENCE: A tumultuous year at parent Havas led to management change at Euro RSCG, its largest global network. Despite the changes, Euro's largest U.S. office, New York, fought back after the exit of one of its biggest clients, Intel. David Jones, former head of Euro New York, replaced Jim Heekin as worldwide CEO; he leads in conjunction with Executive Co-Chairs Mercedes Erra and Stephane Fouks and Chief Creative Officer Remi Babinet, all in France. Cutting its losses, Euro decided in January not to defend Intel and instead focus on new business. It paid off: in March, Euro reeled in global creative duties on Jaguar.
