Between 1956 and 2005, about 1,500 malls were built, including the Mall of America, one of the world's biggest -- 4.2 million square feet of stores, an amusement park, even a wedding chapel. And it attracts millions of visitors each year, from all over the world.

"All of a sudden, the consumer now has every single retail store throughout the world a key tap away," said Lewis.
