In the last decade or two, Hello Kitty has exploded into a pop culture icon from Japan to the United States, and no one quite knows the reason why. Could it be her 22,000 products on the market in every item imaginable, her appeal to all ages from infants to grown adults well into their 20's, or simply her cuteness?

Hello Kitty has been chosen to be Japan's official ambassador to welcome visitors from China and Hong Kong!

Hello Kitty has even been made into a makeup and hair ad!

Hello Kitty has her own line in MAC Cosmetics.
