Black Friday was named by traffic police, not by accountants

Most explanations of the naming of Black Friday stop at the point where it starts to matter. This one carries on.

The explanation everyone repeats

The standard story is that retailers spend most of the year making a loss and finally move into the black on the day after Thanksgiving. It is repeated in news coverage every year and appears in advertising, which gives it enormous circulation.

The claim about annual profitability is not how retail accounting works, since profitability is not determined by a single day. It also fails to explain why the word black would be chosen, given that black in commercial usage generally has negative associations. Black Monday, Black Tuesday and Black Wednesday all refer to disasters, which makes the positive reading an outlier.

What the earliest uses describe

The term appears in mid-twentieth-century American usage describing the day after Thanksgiving in a specific city. It was reportedly used by police and transport workers facing enormous crowds, congested streets and compulsory overtime. The name captured a day that was miserable to work rather than a day that was profitable to trade.

Similar constructions were used elsewhere for days of unusual congestion, which fits the general pattern of the word. That usage predates the accounting explanation by a considerable margin, which is the decisive point.

The attempted rebranding

Local retailers reportedly disliked the association and tried promoting an alternative name with positive connotations. That effort failed, as attempts to replace an established informal name almost always do.

The successful strategy was not to change the name but to change what it was said to mean. Reframing an existing term is far cheaper than replacing it and does not require anyone to learn a new word. The accounting story is best understood as that reframing, and it worked completely.

How the day changed

The event has expanded from one day to a period stretching across a week or more in many countries. It has also been exported to markets with no Thanksgiving holiday at all, where the name is entirely detached from its origin. That export is a useful demonstration that the word now carries a commercial meaning independent of any calendar.

Online trading has further weakened the connection to physical crowds, which was the original referent.

A term that began as a complaint about traffic now describes a global promotional season.

What the discounts are worth

Consumer groups in several countries have compared advertised prices against the same items in preceding and following months. The general finding is that a substantial proportion of promoted items were available at the same or lower price at other times.

Somewhere in the retelling, genuine reductions do exist, particularly on discontinued lines and on products with high stock levels. Reference pricing rules differ by jurisdiction, and some countries regulate how a previous price may be advertised. Checking price history before the day is the only reliable way to tell which category a given deal falls into.

Printing a correction has a poor record of taking a myth out of circulation.

Why the false origin is useful

It converts a name about congestion and stress into a name about prosperity, which suits everyone selling something. It also gives shoppers a flattering role, as participants in the moment a business becomes viable. Origin stories that make a commercial event feel meaningful are worth real money and cost nothing to circulate.

The genuine origin is documented well enough to check, which makes this an unusually clean example. It is worth noticing how often the explanation for a name turns out to be the marketing department's second attempt.

The takeaway

It was a complaint about traffic, the shops objected, and then somebody thought of a better story for the same word.

The satisfying version of a story is the one that travels, which is the whole problem.
