Decoder Ring Plus: The Surprising History of Halloween

Every year, Halloween keeps getting bigger, spooky season starts earlier, and costumes are more elaborate and in more stores than ever before. To understand these trends, host Willa Paskin spoke to Lisa Morton, a Halloween lover and expert who has written extensively about the holiday’s history. Lisa explained that certain traditions, like costumes, candy, and frights—that’s all relatively new. In this episode, she traces Halloween back to the ancient Celtic holiday of Samhain, through the invention of “Trick or Treat” during the Great Depression, to the rise of ubiquitous Spirit Halloween stores.
