Media industry veteran Jack Klues, long-time boss of Publicis Groupe’s VivaKi media operation, is to retire at the end of the year. CFO Frank Voris is taking over with Rishad Tobaccowala as chief strategy and innovation officer (the media man presumably). At the same Publicis Groupe, CEO Maurice has announced that Vivaki will become a "separate business unit" open to all PG’s agencies as opposed to just the big media agencies.
