UNLIKE ART, which by definition is free of commercial agenda, design has served as a powerful tool for business since the dawn of the industrial age. It has built global brands, disrupted industries, and changed our lives with technologies. As ours became a civilization fueled by selling “stuff,” design was the means by which that stuff was created. And just as the nature of business has changed radically since Henry Ford invented the assembly line, transformations of the purpose and function of design have been extreme. These metamorphoses can be tracked along multiple dimensions: in the role and influence of the designer, in what is designed, and in design’s intention and impact.
