For decades, supermarkets were simply retailers, acting as the link between food producers and consumers. It is becoming a powerful ecosystem that controls large parts of the food supply chain. Consumers increasingly expect retailers to demonstrate environmental responsibility, and supermarkets recognise that sustainability is becoming a competitive advantage as well as a social responsibility. Some analysts believe supermarkets will increasingly resemble technology companies, using data and artificial intelligence to manage every stage of the shopping journey. The supermarket has become far more than a shop—it has become one of the most powerful forces in the modern food industry.
