Patrick Courrielche
In 2015, Courrielche wrote a long form story "St. Nicholas: The Birth Of A Social Weapon" on the origin of Santa Claus and introduced the concept of a "social weapon" - a packaged idea, message, or product that is used by an individual or group to advance their cause. Courrielche argued that New York City elites crafted Santa Claus from St. Nicholas, a widely known patron saint, to stabilize a city plagued by annual misbehavior every December. Santa Claus was then used as a "social weapon" by merchants, craftsman, city rulers, parents, newspapers, and others to benefit their endeavors. The essay was added to the St. Nicholas Center's resource on the Origin of Santa Claus.
Santa Claus
Santa Claus appears in the weeks before Christmas in department stores or shopping malls, or at parties. The practice of this has been credited to James Edgar, as he started doing this in 1890 in his Brockton, Massachusetts department store. He is played by an actor, usually helped by other actors (often mall employees) dressed as elves or other creatures of folklore associated with Santa. Santa's function is either to promote the store's image by distributing small gifts to children, or to provide a seasonal experience to children by listening to their wishlist while having them sit on his knee (a practice now under review by some organisations in Britain, and Switzerland). Sometimes a photograph of the child and Santa are taken. Having a Santa set up to take pictures with children is a ritual that dates back at least to 1918.
