Since the early twentieth century, the cinema of the United States, often referred to as Hollywood, has had a significant impact on the film industry in general. Historically, the main form of American cinema has been traditional Hollywood cinema, which evolved between 1913 and 1969 and continues to be representative of the majority of films produced in the country to this day. While the Frenchmen Auguste and Louis Lumière are often regarded as the founders of modern film, some historians disagree. This country's national cinema generates the most amount of movies of any single-language national cinema, with an average of more than 700 English-language movies being produced each year.
The big Hollywood film studios are the main source of the most financially successful and highest grossing films in the world, as measured by box office receipts. Furthermore, several of Hollywood's top pictures have earned more money at the box office and generated more box office sales outside of the United States than films produced in other countries.
Today, American film studios together create several hundred films each year, making the United States one of the world's most prolific producers of motion pictures and a major innovator in the fields of motion picture technology and engineering.
