Officials with the Bloomington mall say scammers pretending to be affiliated with the mall are calling consumers in hopes of gaining their credit card numbers or other personal information. Within 24 hours the mall received a couple dozen complaints.

The magazine says the entire timeline of mall development can be carved into two eras: Before MoA and After MoA. The Bloomington mall gets about 40 million visitors a year, according to the magazine, which puts it well ahead of anyone else.

The MOA is 20! Time flies when you're shopping. In two decades, the Mall of America has weathered criticism, economic downturns and occasional bad publicity, but officials with the Megamall say the international tourist draw has a bright future.

The world-famous megamall is gearing up to celebrate its 20th anniversary. The mall is planning giveaways, free movies and a birthday party with 2,000 pieces of cake.
