Barbie and her best male friend Ken have been described as two most popular dolls in the world. Since its launch, Barbie has transformed the toy business in affluent communities globally by becoming a vehicle for the sale of related merchandise (accessories, clothes, friends and relatives of Barbie, etc.). Writing for Journal of Popular Culture in 1977, Don Richard Cox noted that Barbie has a significant impact on social values by conveying characteristics of female independence, and with her multitude of accessories, an idealized upscale life-style that can be shared with affluent friends.
