Overview
Black Friday is a colloquial term for the Friday after Thanksgiving in the United States. It traditionally marks the start of the Christmas shopping season in the United States. Many stores
offer highly promoted sales at discounted prices and often open early, sometimes as early as midnight or even on Thanksgiving. Some stores' sales continue to Monday ("Cyber Monday") or for a week ("Cyber Week").
Black Friday has routinely been the busiest shopping day of the year in the United States.
Etymology
For centuries, the adjective "black" has been applied to days upon which calamities occurred. Many events have been described as "Black Friday", although the most significant such event in American history was the Panic of 1869, which occurred when financiers Jay Gould and James Fisk took advantage of their connections with the Grant Administration in an attempt to corner the gold market. When President Grant learned of this manipulation, he ordered the Treasury to release a large supply of gold, which halted the run and caused prices to drop by 18%. Fortunes were made and lost in a single day, and the president's own brother-in-law, Abel Corbin, was ruined.
