A tire manufacturer created a restaurant rating system to encourage driving, which would wear out tires and sell more product. The credibility came precisely because the rater had no stake in the food industry, making its judgments appear disinterested and therefore trustworthy.
Inspectors visit and pay as ordinary customers, return multiple times, and never reveal themselves, so establishments cannot perform for the judge. Reputation rests on the consistency of the everyday experience rather than a curated showcase moment.
By withholding the top rating from the vast majority and removing stars when standards slip, the system keeps each award rare and meaningful. The willingness to revoke recognition is what makes granting it valuable.
Separating distinctions like the star tiers from the budget-friendly recommendation lets a single brand certify quality across price points without diluting its premium signal. Each tier communicates a distinct kind of value rather than a single hierarchy of better-or-worse.
In 1900, André and Édouard Michelin, whose tire company was in Clermont-Ferrand, France, printed about 35,000 copies of a free guide for the country's few thousand motorists, listing mechanics, fuel stops, maps and places to eat and sleep. According to the company's founding story, around 1920 André found copies being used to prop up a workbench at a tire dealer, and concluded that people do not respect what they get for free. Michelin then began charging 7 francs for the guide, dropped its paid advertising, and in 1926 started awarding a single star to fine-dining restaurants, expanding to three tiers in the early 1930s.
