A troll doll, also known as a Dam doll, is a type of plastic doll with furry hair depicting a troll. They were originally created in 1959 by Danish woodcutter Thomas Dam. They became one of the United States' biggest toy fads in the early 1960s. They became fads again in brief periods from the 1970s through the 1990s and were copied by several manufacturers under different names. During the 1990s several video games and a video show based on troll dolls were created. In 2003 the Dam company restored their United States copyrights, stopping unlicensed production. In 2005 the brand was modernized under the name Trollz, but it failed in the marketplace.
Troll dolls were originally created in 1959 by Danish fisherman and woodcutter Thomas Dam. Dam could not afford a Christmas gift for his young daughter Lila and carved the doll from his imagination. When other children in the Danish town of Gjøl saw the troll doll, they wanted one as well. Dam's company Dam Things began producing the dolls in plastic under the name Good Luck Trolls. The dolls became popular in several European countries during the early 1960s, shortly before they were introduced in the United States. They became one of the United States' biggest toy fads from the autumn of 1963 through 1965. The originals, also called Dam dolls, were of the highest quality, featuring sheep wool hair and glass eyes. Their sudden popularity, along with an error in the copyright notice of Thomas Dam's original product, resulted in cheaper imitations and knock-offs which flooded the North American shelves.
