Former Accenture Song ANZ boss, now global CEO of its creative arm, Droga5, Mark Green, has batted-off market rumblings about a slow start to its plans to shake-up the Australian media agency sector with a full-service media planning and buying unit, telling Mi3 during a recent visit to Australia that “from what I can see from my week here, they’ll be making some very big moves very soon.” Asked if that might include Optus, which is reviewing its media buying contract, currently with IPG’s UM, in which Accenture Song, Wavemaker and UM are said to be in the final three, Green would not be drawn but said “we’re confident we will make some headway over the next month or so” on new business.
