In the 1960s Barbie's friends joined the line up of fashion dolls. Ken was her boyfriend and came to be in 1962. The Ken doll got his name from Ruth's son. Midge was her friend who was a redhead meeting the toy marketplace in 1963, a year after Ken. Allen was Ken's friend. Skipper was her little sister that was produced in 1964. Tutti and Todd were her twin siblings were introduced in 1966. Francie was her adult cousin. In 1967, Francie was changed into the first black Barbie doll causing consumers to believe it reflected the support of interracial marriages. Since this was during Civil Rights' time, she was not very successful. Twelve months later Mattel introduced Christie, the second black Barbie, who was much more accepted. Cara and Julia were also produced as Barbie's black friends. The roles of Barbie evolved as equality for women's rights progressed. The doll started in the 1960s portraying stereotypical female positions like teacher, stewardess, nurse, etc. A series of novels were also written introducing Barbie and her birthplace in the 60's. Bendable legs and swivel hips were introduced on Barbie in 1965. Jack Ryan created them.
