Barbie was based on a German doll called Lilli, Mattel (the owners of the Barbie brand) acquired the rights of the Bild Lilli doll in 1964 so the production of “Lilli” had to stop.

(According to M.G. Lord, the author of “Forever Barbie: The Unauthorized Biography of a Real Doll,” Lilli — “an eleven-and-a-half inch, platinum ponytailed” German doll was a toy for German men! She was based on a popular post-war cartoon character who first appeared in the West German tabloid Bild Zeitung in 1952. A professional floozy of the first order, Bild Zeitung’s Lilli traded sex for money, delivered sassy comebacks to police officers, and sought the company of “balding, jowly fatcats”. A German brochure from the 1950s said that Lilli (the doll) was “always discreet,” while her complete wardrobe made her “the star of every bar.”

It looks as if Barbie couldn’t stand the competition. So, what’s the sentence for dollicide?)
