Barbie is an interesting toy to me.  A solid role model for girls who does basically everything in the world.
I've loved Barbie since I was a little girl, and then grew up to get into marketing for children's toys. She's such an icon.. a figurehead for the toy fashion doll market for the last 50 years. But heck, there's still been controversies and lawsuits, and even parodies of her and her lifestyle. Guess that speaks to her popularity.
