General Motors has replaced Minneapolis-based Fallon on Cadillac’s creative account with a trio of Interpublic shops, AdAge reports.
Hill Holliday, based in Boston, will lead the creative and strategic work, with Campbell-Ewald handling account management and Lowe taking on digital advertising.
According to Crain's Detroit Business sources, the three agencies combined are being called ‘Rogue’.
Publicis Groupe’s Fallon handled the account, estimated to be worth $250m, for three years but failed to retain the business following a review earlier this year.
Publicis Groupe retains creative for GMC and Buick at Leo Burnett, while Carat handles media duties globally for General Motors.
An official announcement is expected tomorrow, 12 June.
