The origins of Barbie go back to the early '50's. She is most commonly portrayed as a 6 foot tall, perky, long blond haired white female. She can be seen swimming in her mansions pool, or helping animals when they are sick. She symbolizes the woman of America.
The origins of Bratz goes back to the early '90's. They are urban, can be seen at parties, and come in a variety of races, but they are not as popular as a common Barbie doll. Their lips and heads are too big for their bodies, and they flirt with boys, making them not so innocent.
They are both dolls we used to play with as kids, but the images they put out are just some of the ways media shapes our views and ideas on race. The barbie doll unintentionally shapes the way girls and women see themselves. The barbie doll is perfect, perfect voice, hair, makeup, body and skin. She is what a white woman supposed to be: polite, kind, always happy, perky and suburban.
Bratz however get rid of the stereotype by having the main dolls of different races: white, black, latin, and asian. They represent a more realistic common girl in America.
