Tribble Ad Agency : The Advertising Agency of Record

Tom Carroll to replace Jean-Marie Dru as chief executive of TBWA\Worldwide, as part of a reshuffle of senior executives at the advertising agency network. Carroll will keep his position of president, with Dru to become chairman of the group. Lee Clow, currently chairman and chief creative officer, will become a newly created position called global director of media arts.

The reshuffle is partly blamed on some losses TBWA has had in recent years. Competition from Google and search marketing and optimization firms was called by lower ranking employees as another factor.
