Many people have a favorite holiday story (or song) even if they don’t celebrate the holiday. Many people find hope and meaning in a Christmas tale — or the Chanukah story —  even if they’re not Christian or Jewish (or religious in any way). People seeking that hope is the reason why theatrical productions of holiday stories, like A Christmas Carol (which was first published on December 19, 1843), are cash cows for non-profits. People wanting to “get into the spirit” also the reason why watching holiday movies, like It’s a Wonderful Life (which premiered today, December 20, 1946), is a tradition for so many families.
