28 mm film was introduced by the Pathé Film Company in 1912 under the name Pathé Kok. Geared toward the home market, 28 mm utilized diacetate film stock rather than the flammable nitrate commonly used in 35 mm. The film gauge was deliberately chosen such that it would be uneconomical to slit 35 mm nitrate film. 27 mm was not acceptable because the left over part was 8 mm wide and thus useable in the 8 mm format.
Pathé in France and later Victor in the USA printed reduction prints (usually, although not always, abridged) of popular films for home rental, designed to be used in Pathéscope Cinematograph or Victor Animatograph projectors. By 1918, over 10,000 projectors had been sold and more than 20,000,000 feet of film printed.
World War I stopped European production of 28 mm. It continued in North America until 1920 before ceasing entirely. Shortly after, 9.5 mm and 16 mm would take the amateur film gauge role 28 mm had once filled.
