Sunline, Inc., became a division of the Sunmark of St Louis' group of companies, which was later acquired in 1986 by Rowntree Mackintosh of the United Kingdom, which was, in turn, taken over by Nestlé. The Willy Wonka brand candies were developed by Sunmark in a joint-venture with The Quaker Company. Sunmark eventually acquired the rights to Willy Wonka and established a division with that name which produced the Willy Wonka brands. The Wonka symbol was subsequently applied to most Sunmark brands. Nestlé has since sold its confectionery businesses to Ferrero SpA.
