The term storyboarding is often used in the eLearning industry, but sometimes it seems it's more a buzzword than a commonly understood idea. To understand it better and to understand the art behind it, we first need to go back in history a bit. Storyboarding was first used by Walt Disney for the 1928 animation, "Plane Crazy."

Walt's method quickly evolved to a form still in use today. He employed it in developing the most famous of early animated cartoons—which brought the birth of Mickey Mouse - in 1932's "Steamboat Willie." Disney used the fundamental storyboard we still use today in eLearning—side-by-side panels with text on one side describing the content on that screen, with a sketch of what the screen will look like on the other side (See Figure 1):
