Who would have thought Chanel and Spam would share a category? But they do--the two are among the world's fastest-selling brands. Several popular products and how fast they fly off store shelves:
* Two Mattel Barbie dolls sell every second worldwide.
* A bottle of Chanel No. 5 fragrance is sold every three seconds worldwide.
* About 13 boxes of Jell-O are sold every second in the United States
