 Barbie sales began plummeting in 2012, thus removing focus from the Disney Princess line.Mattel had only sold Cinderella, Ariel, Belle, and the two Frozen princesses during the last year or so of its license.With these competing lines and an expiration of the brand license at the end of 2015, Disney gave Hasbro a chance to gain the license given their work on Star Wars, which led to a "Descendants" license.
