It seems Thornhill Industries has been on a hiring spree.

— Harold Finch

Thornhill Corporation is an organization founded by the Machine under its "Ernest Thornhill" alias. Its function is to serve as a human face and a cover for operations such as hiring and purchases conducted directly by the Machine.



The Thornhill Corporation was created sometime before the events of “Zero Day” as the product of the Machine's survival instinct. As Finch programmed it to delete its memories daily, the Machine needed a way to preserve them. So it created a data entry orginazation: at night the Machine would print out its memories and during the day, employees would input the code back into the Machine.
