The term "Black Friday" originated on September 24, 1869, after two investors caused a stock market crash by driving up the price of gold. Along with a 20% drop in the stock market that day, farmers also experienced a 50% drop off in harvest value for both corn and wheat.  The term returned nearly a century later in the 1950s. Police officers used the phrase, "Black Friday," in reference to the Friday between Thanksgiving and the annual Army-Navy college football game. People would use this day to travel into town to shop, forcing local police forces to work longer hours in order to manage the influx of both traffic and shoppers. Eventually, businesses began to adopt the term, though they originally tried to coin it as "Big Friday." The new name never stuck and by the 1980s, "Black Friday" became the go-to phrase associated with the massive shopping day.
