Sears, Roebuck and Co. (usually known only as Sears, or Sears and Roebuck among older Americans and Southerners) is an American mid-range chain of international department stores, founded by Richard Sears and Alvah Roebuck in the late 19th century. It operates in Canada under Sears Canada and Mexico under Sears Mexico. From its mail order beginnings, the company grew to become the largest retailer in the United States by the mid-20th century, and its catalogs became famous. Competition and changes in the demographics of its customer base challenged the company after World War II as its rural and inner city strongholds shrank and the suburban markets grew. Eventually its catalog program was largely discontinued. Sears merged with Kmart in early 2005, creating the Sears Holdings Corporation.
