Many people think that the term "Black Friday" comes from the belief that businesses run at a loss, or "in the purple," until the day following Thanksgiving when large sales allow them to display profits, or "in the black."

Furthermore, many firms provide their employees with a day off as part of the Thanksgiving holiday weekend.
