In 1973, Sears, Roebuck & Co., the largest retailer in the world at the time, moved into its new headquarter at 233 S. Wacker Drive in downtown Chicago. The massive building gained its own zip code thanks to the company’s skyrocketing shopping catalog business. In order to deal with the immense volume of mail orders from across America every day, Sears designed designated mail robots called “Little Bo Beep” to distribute mail inside the tallest building at the time. The mail circulation, riding the complex elevator system in Sears Tower, is therefore abstracted into an epitome of the company’s glorious success as the “Amazon” of its time.
