Vaudeville is a theatrical genre of variety entertainment which began in France at the end of the 19th century. A vaudeville was originally a comedy without psychological or moral intentions, based on a comical situation: a dramatic composition or light poetry, interspersed with songs or ballets. It became popular in the United States and Canada from the early 1880s until the early 1930s, while changing over time.
