After 35 mm Kodachrome color film was introduced in 1936, a new standard 2×2 inch (5×5 cm) miniature lantern slide format was created to better suit the very small transparencies the film produced. In advertising, the antique "magic lantern" terminology was streamlined, so that the framed pieces of film were simply "slides" and the lantern used to project them was a "slide projector". The old-fashioned magic lantern show became an up-to-date "slide show".
