From the start, Sears’s genius was to market itself to consumers as an everything store, with an unrivaled range of products, often sold for minuscule profits. The company’s feel for consumer demand was so uncanny, and its operations so efficient, that it became, for many of its diehard customers, not just the best retail option, but the only one worth considering.

By building a large base of fiercely loyal consumers, Sears was able to buy more cheaply from manufacturers and wholesalers. It managed its deluge of orders with massive warehouses, like its central facility in Chicago, in which messages to various departments and assembly workers were sent through pneumatic tubes. In the decade between 1895 and 1905, Sears’s revenue grew by a factor of 50, from about $750,000 to about $38 million, according to Alfred D. Chandler Jr.’s 1977 book The Visible Hand: The Managerial Revolution in American Business. (By comparison, in the last decade, Amazon’s revenue has grown by a factor of 10.)

Then, after one of the most successful half-centuries in U.S. corporate history, Sears did something really crazy. It opened a store.

In the early 1920s, Sears found itself in an economy that was coming off a harsh post-World War recession, according to Daniel M. G. Graff and Peter Temin’s essay “Sears, Roebuck in the Twentieth Century.” The company was also dealing with a more lasting challenge: the rise of chain stores. To guide their corporate makeover, the company tapped a retired World War I general named Robert Wood, who turned to the U.S. Census and Statistical Abstract of the United States as a fount of marketing wisdom. In federally tabulated figures, he saw the country moving from farm to city, and then from city to suburb. His plan: Follow them with stores.

The first Sears stores opened in the company’s existing mail-order warehouses, for convenience’s sake. But soon they were popping up in new locations. Not satisfied with merely competing with urban department stores like Macy’s, Wood distinguished new Sears locations by plopping them into suburbs where land was cheap and parking space was plentiful.

Sears’s aesthetic was unadorned, specializing in “hard goods” like plumbing tools and car parts. Wood initially thought that young shoppers would prefer a cold, no-frills experience—he likened the first stores to “military commissaries.” This was a rare misstep; Sears ultimately redesigned their stores to appear more high-end.

The company’s brick-and-mortar transformation was astonishing. At the start of 1925, there were no Sears stores in the United States. By 1929, there were 300. While Montgomery Ward built 90 percent of its stores in rural areas or small cities, and Woolworth focused on rich urban areas, Sears bet on everything—rural and urban, rich and poor, farmers and manufacturers. Geographically, it disproportionately built where the Statistical Abstract showed growth: in southern, southwestern, and western cities.
