Metro Goldwyn Mayer
By the 1920s films were an established industry with a definitive internal hierarchy. The “Big Five” studios were Warner Bros Pictures, Paramount Pictures, RKO Pictures, MGM, and Fox Film Corporation. The “Little Three” were Universal Pictures, United Artists, and Columbia Pictures. By this time studios had consolidated all aspects of film development underneath one banner, rather than breaking up the process among many smaller companies. Film development was more lucrative than ever.
