During the administrations of Presidents Wilson, Harding, Coolidge, and Hoover, the National Photo Company supplied photographs of current news events in Washington, D.C., as a daily service to its subscribers. It also prepared sets of pictures on popular subjects and undertook special photographic assignments for local businesses and government agencies. The bulk of the images were created between 1909 and 1932. The photographic files of the National Photo Company, including an estimated 80,000 images (photographic prints and corresponding glass negatives), were acquired by the Library from its proprietor Herbert E. French in 1947.

By 1908 there were 10,000 permanent movie theaters in the U.S. alone. For the first thirty years, movies were silent, accompanied by live musicians, sound effects, and narration. Until World War I, movie screens were dominated by French and Italian studios. During Great War, the American movie industry center, "Hollywood," became the number one in the world. By the 1920s, the U.S. was producing an average of 800 feature films annually, or 82% of the global total. Hollywood's system and its publicity method, the glamourous star system provided models for all movie industries. Efficient production organization enabled mass movie production and technical sophistication but not artistic expression. In 1915, in France, a group of filmmakers began experimenting with optical and pictorial effects as well as rhythmic editing which became known as French Impressionist Cinema. In Germany, dark, hallucinatory German Expressionism put internal states of mind onscreen and influenced the emerging horror genre. The Soviet cinema was the most radically innovative. In Spain, Luis Buñuel embraced abstract surrealism and pure aestheticism. And, just like that, at about its peak time, the silent cinema era ended in 1926-1928.
