Barbie’s real name is Barbara Millicent Roberts, and she’s named after the daughter of  Mattel’s co-founders, Ruth and Elliot Handler.
Barbie is a fashion doll manufactured by the American toy company Mattel, Inc. and launched in March 1959. American businesswoman Ruth Handler is credited with the creation of the doll using a German doll called Bild Lilli as her inspiration

Ruth Handler watched her daughter Barbara play with paper dolls, and noticed that she often enjoyed giving them adult roles. At the time, most children's toy dolls were representations of infants. Realizing that there could be a gap in the market, Handler suggested the idea of an adult-bodied doll to her husband Elliot, a co-founder of the Mattel toy company. He was unenthusiastic about the idea, as were Mattel's directors.

The first Barbie doll wore a black and white zebra striped swimsuit and signature topknot ponytail, and was available as either a blonde or brunette. The doll was marketed as a "Teen-age Fashion Model," with her clothes created by Mattel fashion designer Charlotte Johnson. The first Barbie dolls were manufactured in Japan, with their clothes hand-stitched by Japanese homeworkers. Around 350,000 Barbie dolls were sold during the first year of production.

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 11½ inches tall.

In 2009, Barbie celebrated her 50th birthday. The celebrations included a runway show in New York for the Mercedes-Benz Fashion Week. The event showcased fashions contributed by fifty well-known haute couturiers including Diane von Fürstenberg, Vera Wang, Calvin Klein, Bob Mackie, and Christian Louboutin.
