Walmart Inc.
A retail giant that runs thousands of stores and online shopping under the Walmart, Walmart Neighborhood Market, and Sam's Club brands, selling groceries and everyday goods at low prices across the U.S. and dozens of other countries. Sam Walton opened the first Wal-Mart Discount City in Rogers, Arkansas, in 1962 after his discount-store idea was rejected by his previous employer. The name blends his surname with "mart," short for market.
