Barbie Pink

Her signature colour is pink.

Ruth Handler watched her daughter Barbara at 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.

During a trip to Europe in 1956 with her children Barbara and Kenneth, Ruth Handler came across German toy doll called Bild Lilli. The adult-figured doll was exactly what Handler had in mind, so she purchased three of them. She gave one to her daughter and took the others back to Mattel. The Lilli doll was based on a popular character appearing in a comic strip drawn by Reinhard Beuthin for the newspaper Die Bild-Zeitung. Lilli was a working girl who knew what she wanted and was not above using men to get it. The Lilli doll was first sold in Germany in 1955, and although it was initially sold to adults, it became popular with children who enjoyed dressing her up in outfits that were available separately.

Upon her return to the United States, Handler reworked the design of the doll (with help from engineer Jack Ryan) and the doll was given a new name, Barbie, after Handler's daughter Barbara. The doll made its debut at the American International Toy Fair in New York on March 9, 1959. This date is also used as Barbie's official birthday.

Mattel acquired the rights to the Bild Lilli doll in 1964 and production of Lilli was stopped. 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.

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.

Barbie has become a cultural icon and has been given honors that are rare in the toy world. In 1974 a section of Times Square in New York City was renamed Barbie Boulevard for a week, In 1985 the artist Andy Warhol created a painting of Barbie.

Barbie's full name is Barbara Millicent Roberts. In a series of novels published by Random House in the 1960s, her parents' names are given as George and Margaret Roberts from the fictional town of Willows, Wisconsin.

In the Random House novels, Barbie attended Willows High School, while in in the Generation Girl books published by Golden Books in 1999 she attended the fictional Manhattan International High School in New York City (based on the real-life Stuyvesant High School). She has an on-off romantic relationship with her boyfriend Ken (Ken Carson), who first appeared in 1961. A news release from Mattel in February 2004 announced that Barbie and Ken had decided to split up, but in February 2006 they were back together again.

Barbie has had over forty pets including cats and dogs, horses, a panda, a lion cub, and a zebra. She has owned a wide range of vehicles, including pink Corvette convertibles, trailers and jeeps. She also holds a pilot's license, and operates commercial airliners in addition to serving as a flight attendant. Barbie's careers are designed to show that women can take on a variety of roles in life, and the doll has been sold with a wide range of titles including Miss Astronaut Barbie (1965), Doctor Barbie (1988) and Nascar Barbie (1998).
