Kroger, the US based supermarket giant, teamed up with Microsoft to liven up the classic grocery shopping experience with the help of IoT smart shelves. The Kroger company grew into the largest supermarket chain in the United States by, on the one hand, thinking outside the box to maximize revenue, and on the other, consistently solving customer problems. In the early years of Kroger's growth, that meant creating on-site butchers and bakeries, replacing the prevailing business model where grocery stores purchased baked goods and meat from third party sources.
