Westinghouse Works, 1904 is a collection of American short silent films, each averaging about three minutes in length.
In addition, they cannot be called commercials because they do not advertise individual products and were not exhibited widely to elicit sales.
Bitzer primarily used stationary cameras and fixed lenses, and he typically shot the films in a single continuous take.
The finished films were shown to Westinghouse employees in Pittsburgh, narrated by a speaker.
They were later exhibited at the Louisiana Purchase Exposition in St. Louis (accompanied by organ music), and were received positively by audiences.
