General Motors Is Poised To Fire Its Ad Agency [THE BRIEF]

McCann CEO Harris Diamond cancelled his schedule at the 4A's conference to meet with General Motors instead, Adweek reports, as the automaker prepares to fire Goodby, Silverstein & Partners from its roster. Founder Jeff Goodby traveled to Detroit on Tuesday. GM had asked McCann and Goodby to share the account for more than a year, a relationship that was troubled from the start and became rockier when former GM CMO Joel Ewanick — who had brought Goodby on to the business — exited the company last July. Goodby handled Chevrolet and other brands in the U.S.; McCann was assigned to the international business.
