Chewing Gum Gets Its Patent - December 28, 1869

William Finley Semple was an Ohio dentist who, on December 28, 1869, received the first patent for manufactured chewing gum, claiming it would improve dental health. The irony? He never made or sold any. But his patent opened the door for Thomas Adams to commercialize Mexican chicle in the 1870s, and for William Wrigley Jr. to build a chewing gum empire in the 1890s through revolutionary advertising that convinced Americans they should be constantly chewing gum. In this episode, we trace chewing gum from ancient tree resins to a modern, multi-billion-dollar industry, exploring how Wrigley became one of America's first advertising geniuses by creating demand for something nobody actually needs. We examine gum's golden age with bubble gum and baseball cards, its decline in the smartphone era, its environmental impact as non-biodegradable waste, and what its success teaches us about consumer culture, the power of marketing to normalize behaviors, and how industries profit from convincing us we need products we could live without. Through George Santayana's wisdom about remembering the past, we discover how consumer desires are created, not just discovered patterns that still shape our relationship with countless products today.
