| Universal McCann will oversee GM's media buying in 45 European markets.
Universal McCann will handle the buying and planning in all 45 European markets where GM's brands -- Opel, Vauxhall, Saab and Chevrolet -- do business.
The end of the four-month review marks a significant victory for Universal McCann, which along with Interpublic sibling Initiative controlled much of the business. (Initiative held on to GM's media buying and planning business in the U.K.)
Both agencies have been struggling of late, with Universal McCann losing Nestle's U.S. media buying and planning chores earlier this week, when the Swiss food marketer announced it consolidated the business with Publicis Groupe's Zenith Optimedia.
GM said it plans to release 45 new models and variants in Europe over the next five years.
