The PG-13 rating is introduced by the MPAA.

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.

The Motion Picture Association (MPA) is an American trade association representing the five major film studios of the United States, the mini-major Amazon MGM Studios, as well as the video streaming services Netflix and Amazon Prime Video. 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).
