What is "Black Friday"?
Black Friday is the day following Thanksgiving Day in the United States (the fourth Thursday of November). Since the early 2000s, it has been regarded as the beginning of the Christmas shopping season in the US, and most major retailers open very early (and more recently during overnight hours) and offer promotional sales. Black Friday is not an official holiday, but California and some other states observe "The Day After Thanksgiving" as a holiday for state government employees, sometimes in lieu of another federal holiday such as Columbus Day. Many non-retail employees and schools have both Thanksgiving and the following Friday off, which, along with the following regular weekend, makes it a four-day weekend, thereby increasing the number of potential shoppers. It has routinely been the busiest shopping day of the year since 2005. although news reports, which at that time were inaccurate, have described it as the busiest shopping day of the year for a much longer period of time. Similar stories resurface year upon year at this time, portraying hysteria and shortage of stock, creating a state of positive feedback.
