Researchers at the University of Canterbury concluded from research that examined LEGO catalogues from 1973 to 2015 that weaponry is now included in 30 per cent of kits.
In addition, the building block company has seen an increase in scenarios depicting violence in its toy catalogues over the years, the research found.
LEGO, which was founded in 1949, didn’t introduce weapons into its toy sets until 1978, when a castle kit was released which included swords, axes and lances.
“To catch the attention of their customers, toy manufacturers are similarly locked in a metaphorical arms race for exciting new products,” the study said. “Playing out conflict is a natural part of how children play and it helps them learn how to deal with conflicts in their own lives”
LEGO spokeswoman Kathrine Bisgaard Vase said that “weapon-like elements in LEGO sets are part of a fantasy setting and not a realistic daily-life scenario.”
With electronic games threatening the future of the nearly bankrupt company in 2004, LEGO began to embrace popular culture, selling building kits based on movie franchises such as Star Wars, Harry Potter, and Lord of the Rings.
Since then the Danish company has seen 11 years of growth, culminating in 2015’s announcement that net profit for that year had rocketed 31 per cent to $1.4 billion. (£1 billion).
