Birth Barbie

Ruth Handler believed that it was important for Barbie to have an adult appearance, and early market research showed that some parents were unhappy about the doll's chest, which had distinct breasts. Barbie's appearance has been changed many times, most notably in 1971 when the doll's eyes were adjusted to look forwards rather than having the demure sideways glance of the original model.
Barbie was one of the first toys to have a marketing strategy based extensively on television advertising, which has been copied widely by other toys. It is estimated that over a billion Barbie dolls have been sold worldwide in over 150 countries, with Mattel claiming that three Barbie dolls are sold every second.
The standard range of Barbie dolls and related accessories are manufactured to approximately 1/6 scale, which is also known as playscale. The standard dolls are approximately 11 1/2 inches tall.
Barbie products include not only the range of dolls with their clothes and accessories, but also a large range of Barbie branded goods such as books, apparel, cosmetics and video games. Barbie has appeared in a series of animated films and is a supporting character in Toy Story 2 and Toy Story 3.
