Jack Joseph Valenti was an American political advisor and lobbyist who served as a Special Assistant to U.S. President Lyndon B. Johnson. He was also the longtime president of the Motion Picture Association of America. During his 38-year tenure in the MPAA, he created the MPAA film rating system, and was generally regarded as one of the most influential pro-copyright lobbyists in the world.

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).
