Answer:
Absolutely not. The day after Thanksgiving became known as Black Friday. The most relevant explanation is that, traditionally considered the beginning of the holiday shopping season, this was the first day of the year in which retailers made a profit. While all businesses strive to be profitable in every quarter, the truth for many was that they operated at a loss ("in the red") for most of the year and finally made a profit (operated "in the black") beginning on that day. Stores opened early and offered one-day deals and sales, a few items were even sold at a loss to entice shoppers to come.
