A new article posted at History.com explores the evolution of how manufacturers exhibited their products at expositions. In “How Early World Fairs Put Industrial Revolution Progress on Display,” Elizabeth Yuko describes how exhibitors at the 1893 World’s Columbian Exposition used “process exhibits” to give fairgoers “the chance to witness firsthand how everything from glass to shoes to foods were made.”
