The shake-up is arguably the biggest management change at Publicis Groupe since 2014, when the company announced plans for Lévy to step down as CEO in 2017 after 30 years and previously created a Directoire+. Sadoun and King were both appointed to the Directoire+ in 2014 and Sadoun later went on to succeed Lévy as CEO. Lévy welcomed Sadoun's new mandate as CEO and said the Directoire+ was "a formula that has proven its worth in the past" and the creation of the new management line-up "has been the subject of very thorough work". Lévy added: "This team will be in charge of operationalising the 'Power of One' in an even deeper, broader and more demanding way, with the integration of the e-commerce functions now inseparable from all dimensions of marketing and business transformation." Publicis Groupe is the world's second largest agency group with about 90,000 employees.
