On September 3, 1958, the Disneyland anthology series was retitled Walt Disney Presents as it became disassociated with the theme park of the same name. The movement in westerns, which ABC is credited for having started, represented a fifth of all primetime series on American television in January 1959, at which point detective shows were beginning to rise in popularity as well. ABC requested additional productions from Disney. In late 1958, Desilu Productions pitched its detective series The Untouchables to CBS; after that network rejected the show because of its use of violence, Desilu then presented it to ABC, which agreed to pick up the show, and debuted The Untouchables in April 1959. The series went on to quickly become "immensely popular".
