Saatchi & Saatchi’s U.S. Chief Leaving: The advertising firm said the duties of John Fitzgerald, the agency’s U.S. president and chief operating officer, will be assumed by Chairman and Chief Executive Ed Wax. “John has made a real contribution,” Wax said in a statement. “However, following extensive discussions, we have come to realize that we have differing views on the future management of the agency.” The departure of Fitzgerald, who was recruited by Saatchi early this year, had been rumored. New York-based Saatchi & Saatchi Advertising Worldwide, a unit of British firm Cordiant, said it would make no further comment on the situation.
