"Nickelodeon" was originally coined in the United States in the 1880s as a term for a theatre or other place of amusement where the admission fee was five cents (colloquially known as "a nickel"). In the first decade of the twentieth century the term came to be commonly applied to cinemas showing films for a fee of five cents.

In the 1930s the term was used to refer to a pianola or a jukebox which could be operated by inserting a nickel.
