There are different theories about the origin of the term Black Friday.
One of them dates back to 1869 where two Wall Street stockbrokers tried to take over the gold market but everything went wrong and the losses were in the millions on a Friday of this time. For this reason they called it Black Friday.
Another theory regarding this term is recorded for the year 1950, where on Thanksgiving Day people went out to do their shopping to be able to enjoy a soccer game the next day between the army and the navy. The police could not cope with the avalanche of people who went out to do their shopping and they themselves called this day, Black Friday, for their long day of more than 12 hours trying to maintain order in the city of Philadelphia.
The most recent was in 1975, a phrase used by the newspaper The New York Times to refer to the traffic congestion that was generated due to the discounts that stores made after Thanksgiving, bringing to the present a term used more than 100 years ago.
One of the most notable versions about the origin of the popular term is that of the surplus that the accounts recorded on this day, which went from numbers in red to numbers in black thanks to the purchases made on that day. This date is usually the beginning of the Christmas season for different businesses in various countries.
