In 1900 Edmund Munster from Germany took over a liquorice company 'Düsseldorfer Lakritzenwerk. Until the early 1930s, liquorice products took centre stage above the rest of the sweet market. Then in 1930/1931 Edmund Munster acquired the foreign licence to produce a fruity chew with the brand name MAOAM. With a letter dated 21/08/1930, Edmund Munster applied to the district council to copyright the product MAOAM (a chew without gum, made of sugar, syrup and other ingredients). After the chew was made it was then wrapped in wax paper. There were 5 chews in each pack and 50 packs in each box. The copyright was related to the name, the product, the packaging and was extended to potential copies from liquorice, cocoa, sugar and bakery products.
In 1986, Bonn confectionery producer HARIBO appeared on the scene and acquired the Edmund Munster company, which had in the meantime moved its production facilities to modern works in Neuss. The trade mark rights for MAOAM thus also passed to the HARIBO Group.
