   35 mm film is the basic gauge most commonly used for both still photography and motion pictures, and remains relatively unchanged since its introduction in 1892 by William Dickson and Thomas Edison, using film stock supplied by George Eastman. The photographic film is cut into strips 35 mm (about 1 3/8 inches) wide — hence the name. The standard negative pulldown is four perforations per frame along both edges, which makes for exactly 16 frames per foot.
   
   A wide variety of largely proprietary gauges were used by the numerous different camera and projection systems independently invented around the late 19th century and early 20th century, ranging from 13 mm to 75 mm (0.51–2.95 in). Its longevity is largely because its size allows for a relatively good trade off between the cost of the film stock and the quality of the images captured. Additionally, the ubiquity of 35 mm movie projectors in commercial movie theaters makes it the only motion picture format, film or video, which can be played in almost any cinema in the world.
