Shopping cart in supermarket aisle

Shopping carts are icons of modern consumption, designed for efficiency and comfort in grocery aisles.

About this subject

The shopping cart, invented in 1937 by Sylvan Goldman, owner of a supermarket chain in Oklahoma, revolutionized the shopping experience. Before it, customers carried baskets or bags, limiting the volume of items purchased. Goldman noticed that if customers could buy more, sales would increase. He adapted a folding chair, added wheels and a wire basket. The first prototype was an immediate success, but required adjustments: early carts were unstable and hard to maneuver. Today, carts are made of plastic or metal, with ergonomic design and average capacity of 150 to 200 liters. In Brazil, supermarkets invest in carts with child seats, anti-theft sensors, and even electric versions for the elderly. Globally, it is estimated that over 100 million carts are in use, each traveling about 1,500 km per year through aisles. The cart has also become a cultural symbol: appearing in films like "Fight Club" and in memes like "abandoned shopping cart". Interestingly, the basic design has changed little in 80 years, but innovations like GPS-equipped carts and interactive screens are being tested in luxury stores.
