It’s been an urban legend that Atari, having gone nuts mass producing catridges in the expectation they’d sell way more than they did, dumped a ton of them in a landfill and covered them over, with the hopes people wouldn’t realize what they’d done. A documentary crew went back, and sure enough, they were able to unearth proof that the cartridges were in a New Mexico landfill for decades.
This is a pretty fun discovery, and proof that a very successful business can get a bit too cocky and sure. After all, Atari rushed games to market full of bugs and just expected people to buy it; consumers will turn on you if they think the product being sold is sub-par. Atari was never really the same after the peak of the original video game rush, but its legacy lives on, including that fateful decision to landfill a surplus of games.
