Mattel has sold over a billion Barbie dolls, making it the company's largest and most profitable line. However, sales have declined sharply since 2014. The doll has transformed the toy business in affluent communities worldwide by becoming a vehicle for the sale of related merchandise (accessories, clothes, friends of Barbie, etc.). She 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. Starting in 1987, Barbie has expanded into a media franchise, including animated films, television specials, video games and music.
