The Motion Picture Association (MPA) is an American trade association representing the five major film studios of the United States, as well as the video streaming service Netflix. Founded in 1922 as the Motion Picture Producers and Distributors of America (MPPDA) and known as the Motion Picture Association of America (MPAA) from 1945 until September 2019, its original goal was to ensure the viability of the American film industry. In addition, the MPA established guidelines for film content which resulted in the creation of the Motion Picture Production Code in 1930. This code, also known as the Hays Code, was replaced by a voluntary film rating system in 1968, which is managed by the Classification and Rating Administration (CARA).

The cinema of the United States, consisting mainly of major film studios along with some independent films, has had a large effect on the global film industry since the early 20th century. The dominant style of American cinema is classical Hollywood cinema, which developed from 1910 to 1962 and is still typical of most films made there to this day. While Frenchmen Auguste and Louis Lumière are generally credited with the birth of modern cinema, American cinema soon came to be a dominant force in the emerging industry. With more than 600 English-language films released on average every year As of 2017, it produced the fourth-largest number of films of any national cinema, after India, Japan, and China. While the national cinemas of the United Kingdom, Canada, Australia, and New Zealand also produce films in the same language, they are not part of the Hollywood system. Because of this, Hollywood has also been considered a transnational cinema, and has produced multiple language versions of some titles, often in Spanish or French. Contemporary Hollywood often outsources production to the United Kingdom, Canada, Australia, and New Zealand. The major film studios of Hollywood are the primary source of the most commercially successful and most ticket-selling movies in the world.
