Metro-Goldwyn-Mayer Studios Inc. (initialized as MGM) is an American media company, involved primarily in the production and distribution of feature films and television programs. One of the world's oldest film studios.

The studio's official motto, "Ars Gratia Artis", is a Latin phrase meaning "Art for art's sake". It was chosen by Howard Dietz, the studio's chief publicist. The studio's logo is a roaring lion surrounded by a ring of film inscribed with the studio's motto. The logo, which features Leo the Lion, was created by Dietz in 1916 for Goldwyn Pictures and updated in 1924 for MGM's use. Dietz based the logo on his alma mater's mascot, the Columbia University lion.
