A storyboard is a graphic organizer in the form of illustrations or images displayed in sequence for the purpose of pre-visualizing a motion picture, animation, motion graphic or interactive media sequence. The storyboarding process, in the form it is known today, was developed at Walt Disney Productions during the early 1930s, after several years of similar processes being in use at Walt Disney and other animation studios. The storyboarding process can be very time-consuming and intricate. Many large budget silent films were storyboarded but most of this material has been lost during the reduction of the studio archives during the 1970s. The form widely known today was developed at the Walt Disney studio during the early 1930s. The first complete storyboards were created for the 1933 Disney short Three Little Pigs.
