In 2020, Burger King rolled out a new ad where they showed a burger rotting.
They showed a time lapse of the Whopper burger developing molds. The idea behind this was to prove that their products don't use artificial preservatives in their burgers.
The reason they felt they needed to do such an ad was because at that time there were trending videos of other burgers from other companies being left out uncovered for months and developing little to no mold, making people question the levels of artificial preservatives they're being fed.
Even though the message was well received and people understood the intention, there was still a bit of a difference in showing a nasty burger in an ad and still expecting people to buy it.
This ad was unique, it breaks all the rules of meal promotion, usually beautifully-shot items are set up by stylists.
Most people, however, still saw only a decaying burger, didn't really care much about the bigger narrative and so that was all that stayed in their minds.
It caught their attention, but drew mostly a negative response.
