In 1974, the Italian confection manufacturer, Ferrero, launched Kinder Surprise - a new invention from its Kinder product line. In the form of an egg-shaped chocolate shell enclosing a plastic capsule that contains an assembly toy, Kinder Surprise appeals to millions of children throughout Europe -- over 30 billions pieces have been sold. As much as eight thousand different toys have been designed and a hundred new ones are added to the collection each year. When the product was introduced into the markets of the tropical countries such as India, Malaysia, or Ecuador, Ferrero redesigned and renamed it Kinder Egg. One half of the egg is made of chocolate, while the other half contains a toy. Although the design is different from the original, the toy inside the egg continues unfailingly to delight the children.
