Tomorrow is the biggest shopping day of the year in the US – Black Friday. However, a more appropriate description of the day might be “Dark Friday” or “Red Friday” given the wave of violence that has emerged in recent years. In fact, the first references to “Black Friday” were not very positive. In 1966 the Philadelphia Police Department used the term Black Friday to describe the massive traffic jams and overcrowded sidewalks throughout the downtown shopping district. Nearly 100 years earlier in 1869 Black Friday was used to describe a financial crisis. Sometime in the early 1980s the merchant community changed the meaning of Black Friday to reflect the day at which retailers turned profitable for the year. Instead of operating in the red they were now operating in the black.
