The original troll doll was developed by Thomas Dam, of Denmark, and trademarked by Dam Things, Denmark. It became popular in Europe and the United States in the 1960s. The fad reappeared in the United States starting in 1982 when EFS Marketing, Inc. began to market troll dolls in the U.S.A. under an exclusive distributorship contract with Dam Things, Denmark. Under this contract, EFS was given the right to distribute the Dam doll under the trademark "Norfin." However, each Norfin was required to contain the following statement: "This model is designed and copyrighted by Dam Things, Denmark."
