Sears Holdings Corporation was a retail company formed in 2005 through the merger of Sears, Roebuck and Co. and Kmart. It operated a chain of department stores and discount retail outlets across the United States, offering a variety of products, including clothing, appliances, and home goods. The company faced significant financial challenges in the following years, leading to store closures and a decline in sales. In 2018, Sears Holdings filed for bankruptcy, marking a significant shift in the retail landscape as traditional department stores struggled to compete with online shopping and changing consumer preferences.
