Monsters, Inc. (company)
From Pixar Wiki
Monsters, Inc.'s main duty is to provide all citizens in Monstropolis with energy in the form of captured screams collected from children. They accomplish this by crossing into the human world through the closets of children's bedrooms and scaring them to the best of their ability. The screams are then collected in special canisters for use as energy.
The factory is an immense facility equipped to fulfill the needs of its employees, including the "Scare Floor", where the monsters cross over into the human world using the doors of the children's closets. Each Scarer has an assistant to help coordinate the energy collection. Any door belonging to a child who has no fear of monsters is promptly destroyed in the Door Shredder, as their screams cannot be collected.
During the events of the film, it is clear that the company has fallen on hard times, and screams are becoming increasingly difficult to obtain in large amounts because kids have begun to like monsters. Facing a worsening energy crisis, the company sought out new means by which to obtain screams in large quantities.
