But as this week's Samsung news (see left) suggests, holding company wins do not necessarily translate into real passion and understanding for the client's business at the day-to-day agency level.
Meanwhile, Omnicom has unveiled another respectable set of profits figures (page 3). These aren't buoyed by big network acquisitions, mammoth holding company account wins or particularly impressive global new-business coups.
But the 11 per cent rise in profits (a business performance described by the chief executive, John Wren, as "the best in our history") reflects significant local wins and impressive organic growth. Omnicom may not enjoy as many striking headlines as WPP, and Wren may not be as shrewd a player in corporate boardrooms as Sorrell, but the company's performance remains solidly impressive.
