Sindy was designed by Pedigree Dolls & Toys in 1963. A British fashion doll produced to rival the Barbie doll from the US, it had a more wholesome image and design and was successful – it was the top selling toy in the UK in both 1968 and 1970. In the late 1970s, Marx Toys failed to introduce Sindy successfully in the US and Hasbro bought the rights, remodelling it to appeal more to the US market. Consequently, its popularity declined and Mattel, Barbie’s owner, sued for copyright infringement (Hasbro remodelled Sindy's face to settle the claim). Sindy's market share continued to fall in the 1990s (despite Barbie’s ongoing success) and the doll was largely withdrawn in 1997. The rights then reverted to Pedigree and Sindy was relaunched in 1999, this time manufactured by Vivid Imaginations.
