Walmart is the largest retailer on the planet, offering some of the lowest prices you can find anywhere. Walmart opened its first store in 1962 in Rogers, Arkansas. By the end of the 1970s, Walmart had expanded to 276 stores in 11 states. The Walmart Supercenter we have come to know today began showing up around 1988. The brand went international in 1991 when they opened a Sam's Club store in Mexico City. Walmart has come a long way since 1962.
