The SearsTower: We'll NEVER Call it the Willis Tower

The Sears Tower was finished in 1973, and was the tallest building world at the time. It was also a time when Sears Roebuck and Company was the largest retailer in the United States. Now that everybody shops on line, Sears became smaller and smaller and so did the Sears Tower, in comparison with other skyscrapers because not it't the 25th tallest building in the world.
