Business Week Online: "In business, there is big, and there is Wal-Mart. With $245 billion in revenues in 2002, Wal-Mart Stores (WMT ) Inc. is the world's largest company. It is three times the size of the No. 2 retailer, France's Carrefour. Every week, 138 million shoppers visit Wal-Mart's 4,750 stores; last year, 82% of American households made at least one purchase at Wal-Mart. 'There's nothing like Wal-Mart,' says Ira Kalish, global director of Deloitte Research. 'They are so much bigger than any retailer has ever been that it's not possible to compare.' "
