History
In the post-war period, an American architect, Victor Gruen developed a concept for a shopping mall; a planned, self-contained shopping complex complete with an indoor plaza, statues, planting schemes, piped music, and car-parking. Gruen's vision was to create a shopping atmosphere where people felt so comfortable that they would spend more time in the environment, thereby enhancing opportunities for purchasing. The first of these malls opened at Northland Mall near Detroit in 1954. Throughout the twentieth century, a trend towards larger store footprints became discernible. The average size of a U.S. supermarket grew from 31,000 square feet (2,900 m) square feet in 1991 to 44,000 square feet (4,100 m) square feet in 2000. By the end of the twentieth century, stores were using labels such as "mega-stores" and "warehouse" stores to reflect their growing size. The upward trend of increasing retail space was not consistent across nations and led in the early 21st century to the United States having nearly a 2-fold difference in square footage per capita compared to Europe.
