A model (from Middle French modèle//aew), sometimes called a mannequin, is a person who is employed to display, advertise and promote commercial products (notably fashion clothing) or to serve as a subject of works of art.
Modelling ("modeling" in American) is distinguished from other types of public performance, such as an acting, dancing or mime artist, although the boundary is not well defined. Appearing in a movie or a play is almost never considered modelling.
Types of modelling include fashion, glamour, fitness, bikini, fine art, and body-part models. Models are featured in a variety of media formats including books, magazines, movies, newspapers, and TV. Models sometimes are featured in movies (Looker, Tattoo), reality television shows (America's Next Top Model, The Janice Dickinson Modeling Agency), or music videos ("Freedom! '90", "Wicked Game", "Daughters").
