Which American city popularized the term "Black Friday" in the early 20th century?
The term "Black Friday" was originally used derisively by Philadelphia police officers in reference to the traffic the post-Thanksgiving sales caused. Retailers preferred the more polite "Big Friday." Nowadays, Black Friday has become a cultural phenomenon and has spread outside the United States into other countries, as shoppers hunt for great deals. Source: BBC
