BENTONVILLE, AR—Known familiarly as Walmart anyway, the world’s largest retailer is making it official. Effective this coming Feb. 1, the company legally known since 1970 as Wal-Mart Stores Inc. will become, simply, Walmart Inc., reflecting the spelling that founder Sam Walton used when he opened its first location in 1962.
