Jacques Offenbach is most responsible for the development and popularization of operetta—also called or —giving it its enormous vogue during the Second Empire and afterwards. In 1849, Offenbach obtained permission to open the Théâtre des Bouffes Parisiens, a theatre company that offered programs of two or three satirical one-act sketches. The company was so successful that it led to the elongation of these sketches into an evening's duration. However, Offenbach's productions were bound by the police prefecture in Paris, which specified the type of performance that would be allowed: "pantomimes with at most five performers, one-act comic musical dialogues for two to three actors, and dance routines with no more than five dancers; choruses were strictly forbidden." These rules defined what came to be defined as operetta: "a small unpretentious operatic work that had no tragic implications and was designed to entertain the public". Two other French composers, Robert Planquette and Charles Lecocq, followed Offenbach's model and wrote the operettas "Les Cloches de Corneville" ("The Bells of Normandy") and "La Fille de Madame Angot" ("The Daughter of Madame Angot"). The two operettas were considered a major hit.
