The Elf on the Shelf has been around for over 80 years, with the original story first published in 1923. The book was written by Carol Aebersold and her daughters Chanda Bell and Christa Pitts. It was originally intended as a Christmas tradition for families to read together during the holiday season, but over time it became more than just a book. The concept of the Elf on the Shelf grew in popularity, and the toy became a popular Christmas gift.
