The new logo has been inspired by the Art Deco-style sign on Publicis founder, Marcel Bleustein-Blanchet's first office door in 1926. He later brought that door to the agency’s Champs Elysees offices in the 1950s.
The logo will launch across all of Publicis Worldwide’s offices in 84 countries.
The revamped design has been created to distinguish its branding from that of the holding company, Publicis Groupe, which is headed up by Maurice Lévy, the chairman and chief executive.
Arthur Sadoun, the global chief executive of Publicis Worldwide, said: "In many ways the new design reflects our Publicis DNA and what we aim to do for every client we work with. And that is, lead the change.
"The new logo’s Art Deco borrows from our past and the legendary story of Marcel Bleustein-Blanchet, but intentionally incorporates modern characteristics such as symmetry and simplicity."
The logo was conceived and developed by Publicis Worldwide North America.
