The day after Thanksgiving is frequently referred to as "Black Friday". One of the major U.S. holiday shopping days, it is the day many U.S. consumers begin their annual Christmas shopping. The day is heavily promoted by retailers both in newspapers and with television commercials. The origin of the term "Black Friday" comes from the shift to profitability many retailers experience during the holiday season. Black Friday was historically when retailers went from being unprofitable, or "in the red," to being profitable, or "in the black".
