In 1952, composer-lyricist Frank Loesser and orchestrator Don Walker, transformed a fledgling business into what is now known throughout the world as "MTI." In the intervening years, Music Theatre International has become a leader in the theatrical licensing industry, specializing in Broadway, Off-Broadway and West End musicals. Since its founding in 1952, MTI has been responsible for supplying scripts and musical materials to theatres worldwide and for protecting the rights and legacy of the authors who it represents. Whether it is the newest hit from the Broadway or London stage, or a timeless classic, MTI has been a driving force in cultivating new work and in extending the production life of the great American musicals such as, Guys and Dolls, West Side Story, Fiddler On The Roof, Les Misérables, Annie, Of Thee I Sing, Damn Yankees, The Music Man, Godspell, Little Shop Of Horrors, and the musical theatre collection of composer/lyricist Stephen Sondheim, among others.

Apart from the major Broadway and Off-Broadwayshows, MTI is proud to represent youth shows, revues and musicals which began life in regional theatre and have since become worthy additions to the musical theatre canon.
