My first encounter with the concept of bomb fishing was the Shapoklyak episode of the soviet cartoon Cheburashka, produced in the 70s. It's been around.
Yeah it’s been around for a while but it’s been at the individual level not at the commercial scale which makes the practice way worse.
Mine came much later, in the Triplets of Belleville (2003). In case it brings a nostalgic smile to anyone else’s face, too:
