In 1937, Oklahoma grocer Sylvan Goldman introduced the first shopping cart after noticing customers bought only what they could carry; it changed supermarket shopping

Sylvan Goldman invented the shopping cart in the 1930s to help customers carry more items in stores. Initial reactions were negative, as women compared carts to baby strollers while men felt they were unmanly. To boost interest, Goldman employed attractive individuals to demonstrate the carts in stores. The invention resulted in customers purchasing more items and spending more money.
