The Moldy Whopper by Burger King
In a world obsessed with perfection, Burger King chose rot. With “The Moldy Whopper”, the brand launched one of the most daring campaigns in fast food history—showing its signature burger decaying over 34 days. No preservatives. No artificial colors. No filters. Just mold. The message? “The beauty of no artificial preservatives.” It was a bold rejection of industry norms and a visual manifesto for transparency.
Campaign Overview
Developed by INGO Stockholm, DAVID Miami, and Publicis, the campaign featured high-resolution time-lapse photography of a Whopper decomposing over 34 days. The images were used in print, digital, and outdoor ads, showing the burger covered in mold, collapsing into itself.
The campaign launched in February 2020 across the US, Sweden, and select European markets. It was supported by a hauntingly beautiful video set to “What a Difference a Day Makes,” showing the Whopper aging in reverse. The campaign also included educational content about Burger King’s ingredient reform and comparisons to competitors’ preservative practices.
