An incredible marketing campaign by Burger King that spiked a lot of conversation in the media. In a bold move, they showcased a Whopper left in the open air for 34 days, transforming into a moldy, inedible burger. This was a clear contrast to the typically pristine food images in fast food advertising. It's a vulnerable play by Burger King, showing that if you let the burger sit out for days, it will indeed mold. Why? Because they want to show "the beauty of no artificial preservatives". A small jab at the fast food industry, known for artificial ingredients.
