American pantomime, panto for short, refers to works of theatrical entertainment that have been presented in the United States of America since 1876. The works are derived from the entertainment genre of pantomime that developed in England, presented either as they are in Britain or adapted for the American stage and tailored to American audiences. Pantomime in America, as in England, is usually performed at Christmas time. The entertainments, aimed at families, are based on nursery stories and fairy tales, and they incorporate songs (traditional, popular and new), slapstick comedy, often topical jokes, magic, some cross-dressing, local references, audience participation, and mild adult innuendo.
