While other discounters such as Kmart quickly expanded across the country in the 1960s, Sam was able to raise the funds to build only 15 Wal-Mart stores. Wal-Mart got the boost it needed in 1970, when its stock was offered for the first time on the New York Stock Exchange. The public offering created the capital infusion that grew the company to 276 stores by the end of the decade. By focusing on customer expectations, Wal-Mart was growing rapidly in 11 states.
In the 1980s, Wal-Mart became one of the most successful retailers in America. Sales grew to $26 billion by 1989, compared to $1 billion in 1980. Employment increased tenfold. At the end of the decade there were nearly 1,400 stores. Wal-Mart Stores, Inc. branched out into warehouse clubs with the first SAM'S Club in 1983. The first Supercenter, featuring a complete grocery department along with the 36 departments of general merchandise, opened in 1988. Wal-Mart had become a textbook example of managing rapid growth without losing sight of a company's basic values. In Wal-Mart's case, the basic value was, and is, customer service.
Ironically, technology plays an important role in helping Wal-Mart stay customer focused. Wal-Mart invented the practice of sharing sales data via computer with major suppliers, such as Proctor & Gamble. Every time a box of Tide is rung up at the cash register, Wal-Mart's data warehouse takes note and knows when it is time to alert P&G to replenish a particular store. As a result, Wal-Mart stores rarely run out of stock of popular items.
Wal-Mart continues to be the largest retailer in the world today. Their low cost strategy has allowed them to consistently beat their competitors and has contributed to their success.
