Learning from China: Black Friday sale on November 11 mostly online
The U.S. “Black Friday” appears to have started back in 1961 when Philadelphia police described the heavy commercial traffic that followed the Thanksgiving holiday. Businesses began using the term in offering special discounts on that day and it became a nationwide promotion effort by 2003–2004. Because some folks couldn’t shop during that day, or didn’t find what they were shopping for, the National Retail Federation invented Cyber Monday (that followed Black Friday) in 2005. However, Thanksgiving is a uniquely American holiday. Commonwealth countries had long observed Boxing Day and related sales events.
