Vaudeville was a genre of a variety entertainment prevalent on the stage in the United States and Canada from the early 1880s until the early 1930s. so much so that author and theater historian Trav S.D. dubbed vaudeville "the heart of American show business" during that period.[1] It developed from many sources, including the concert saloon, minstrelsy, freak shows, dime museums, and literary burlesque. Vaudeville became one of the most popular types of entertainment in North America, defining an entertainment era. Each evening's bill of performance was made up of a series of separate, unrelated acts. Types of acts included (among others) musicians (both classical and popular), dancers, comedians, trained animals, magicians, female and male impersonators, acrobats, one-act plays or scenes from plays, athletes, lecturing celebrities, minstrels, and short movies.
