The Willy Wonka Candy Company is a British brand of candy owned and licensed by Swiss corporation Nestlé. The Wonka brand's inception comes from materials licensed from British author Roald Dahl. His classic children's novel, Charlie and the Chocolate Factory, and its film adaptations are the source of both the packaging and the marketing styles of the Wonka brand. The brand was launched in 1971, coinciding with the release of the novel's first film adaptation. In 1988 the Willy Wonka Candy Company brand – then owned by Sunmark – was acquired by Nestlé. Nestlé sells sweets and chocolate under the Willy Wonka brand name in the United States, Canada, the United Kingdom, the Republic of Ireland, Australia, New Zealand, Japan, South Africa, Mexico, Colombia, Brazil, Argentina, Costa Rica and Panama.
