Redefining what a trip to the supermarket could be began with the first King Kullen supermarket’s opening in 1930. King Kullen provided the convenience of thousands of items, both in one place and under one roof, as opposed to the typical provision of dry good foods. For the first time, a supermarket included a bakery section with freshly made bread, a meat department with a professional butcher, and a sizable vegetable area, all of which could be purchased through a single checkout line. This was the first of many supermarkets that offered such a range of things in one location, even if it may not appear spectacular by today’s standards. Since then, we’ve created a variety of innovations and technologies that have taken the supermarket beyond its basic design. The shopping cart’s creation in 1937, which occurred shortly after, was essential for effective and lucrative shopping in this enormous supermarket industry. The first price scanner was installed in 1974, ushering in a technology that would dramatically reduce checkout line wait times for decades to come. In Seattle, Washington, Amazon established its first grocery shop without a cashier in 2020, adapting its entirely staff-free convenience store concept to the scale of a supermarket.
