Sears, Roebuck and Company, colloquially known as Sears, is an American chain of department stores founded by Richard Warren Sears and Alvah Curtis Roebuck in 1893, reincorporated by Richard Sears and new partner Julius Rosenwald in 1906. Formerly based at the Sears Tower in Chicago and currently headquartered in Hoffman Estates, Illinois, the operation began as a mail ordering catalog company and began opening retail locations in 1925. The first location was in Evansville, Indiana. In 2005, the company was bought by the management of the American big box chain Kmart, which formed Sears Holdings upon completion of the merger.
Sears had the largest domestic revenue of any retailer in the United States until October 1989, when Walmart surpassed it. In 2018, Sears was the 31st-largest retailer in the United States.
