Jack Valenti, American businessman, created the MPAA film rating system (born 1921)

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 film rating system is used in the United States and its territories to rate a motion picture's suitability for certain audiences based on its content. The system and the ratings applied to individual motion pictures are the responsibility of the Motion Picture Association (MPA), previously known as the Motion Picture Association of America (MPAA) from 1945 to 2019. The MPA rating system is a voluntary scheme that is not enforced by law; films can be exhibited without a rating, although most theaters refuse to exhibit non-rated or NC-17 rated films. Non-members of the MPA may also submit films for rating. Other media, such as television programs, music and video games, are rated by other entities such as the TV Parental Guidelines, the RIAA and the ESRB, respectively.
