They call it “Black Friday” because the day after Thanksgiving used to create such heavy traffic, chaos, and overworked police in Philadelphia that local cops nicknamed it a black day. Later, retailers spun a more positive story, saying it’s when their accounts go from “in the red” (loss) to “in the black ” (profit), and that explanation also became popular.

Quick Scoop

The real origin

  • In the 1950s–1960s, Philadelphia police dreaded the day after Thanksgiving because crowds came in for shopping and the Army–Navy football game, clogging streets and causing accidents and long shifts.
  • They started calling it “Black Friday” to describe the miserable traffic, congestion, and hassle the day created.

How the “profit” story appeared

  • The term sounded negative, so some retailers tried to rebrand it as “Big Friday,” but that never caught on.
  • By the 1980s, businesses pushed the idea that Black Friday is when they go from red ink to black ink in their ledgers, framing the day as a huge profit point and the unofficial start of the holiday shopping season.

What it means today

  • Today, “Black Friday” mainly means a massive sales day, often extending into “Black Friday Week” or even “Black November” with online and in‑store deals.
  • It has also inspired related events like Cyber Monday and other global sales days that copy the same high-discount, high-hype model.
