Trick-or-treating is big business! The chocolate industry is expected to reach $24.9 billion by 2027 (Mintel), and seasonal non-chocolate candy sales "represent a notable portion of candy sales and are growing" (IBISWorld). To learn more about the history of chocolate, candy, and the companies at the center of this industry, check out these books available on the shelves at Pardee or online through the BU Libraries Catalog. Happy Halloween from the Pardee staff!
