About
Historically one of the top-tier global creative agency networks, now merged into 'Leo' under Publicis Groupe
Leo Burnett was founded in Chicago in 1935 by Leo Burnett himself, growing into one of the most celebrated and influential advertising agencies in history. The agency became legendary for its 'human truth' philosophy and its creation of some of advertising's most enduring brand icons, including the Marlboro Man, Tony the Tiger, the Jolly Green Giant, the Pillsbury Doughboy, and Charlie the Tuna. With a deep belief in the power of storytelling and emotional resonance, Leo Burnett built a global network spanning dozens of countries and became a cornerstone of Publicis Groupe's creative portfolio after being acquired by the French holding company. Operating as Leo Burnett Worldwide, the agency served major multinational clients across consumer goods, automotive, healthcare, and financial services, delivering integrated creative campaigns that blended traditional advertising with digital and experiential marketing. Its Chicago headquarters remained a hub of creative culture, and the agency consistently ranked among the top creative networks globally, winning major awards at Cannes Lions and other prestigious industry festivals. The agency was known for its collaborative culture and its commitment to 'HumanKind,' a strategic philosophy centered on creating ideas that change human behavior rather than simply delivering messages. In 2024, Publicis Groupe announced the merger of Leo Burnett and Publicis Worldwide into a new combined creative entity called 'Leo,' effectively ending Leo Burnett's existence as a standalone agency brand. The new constellation, branded simply as Leo, was designed to pool the creative talent and client relationships of both legacy networks into a single, unified global creative agency under Publicis Groupe's broader organizational structure. While the Leo Burnett name carries an extraordinary legacy, the brand as an independent operating entity has been absorbed into this new combined organization.
