Although Hasbro is the larger toy company, Mattel is known as the market's premiere doll manufacturer and the loss of the Disney Princesses and Frozen lines were seen as a major blow to the company. In addition to losing an estimated $400 million in revenue after losing the Disney licenses, Mattel went through a period of active turnover as it tried to right the course after Disney swapped companies. After going through four CEOs, Mattel has stabilized under current head Ynon Kreiz and rebuilt its key brands, including Barbie, in part through a reorganization that sees its business lines defined by types of toys instead of by key audiences. Although this is seen as a major win for Mattel, the loss of the Disney licenses aren't seen as a major loss for Hasbro. While Hasbro produced a wide line of toys under the Disney Princesses and Frozen umbrella, the line was not as lucrative as hoped for the larger toy manufacturer.
