motion pictures (movies, pic(s), pix, or "moving pictures")
Motion pictures refers to the length of film (with or without sound) with a sequence of images that create an illusion of movement when projected. Originally referred to the motion or movement (due to the principle of persistence of vision) perceived when a string of celluloid-recorded images were projected at a rate of 16 or more frames per second. An art form, and one of the most popular forms of entertainment, known archaically as a photoplay during the silent era.
