Michelin (1900): a free motoring guide sells more tires — and becomes the dining authority

In 1900 France had only about 3,000 private cars, and tire maker Michelin lived or died on how much people drove. To make motoring appealing, Édouard and André Michelin published a guidebook for motorists — maps, tire-repair instructions, garages, petrol stations, hotels and restaurants — and gave away 35,000 copies free at the Paris Universal Exposition.

The giveaway worked as a lead-generation channel: the more people traveled by car, the more tires they wore out. The guide was an immediate success and the 1901 edition was printed in double the copies. As motoring matured, its tire pages shrank — from 62 of 600+ pages in 1912 to 5 of 990 by 1927 — while its restaurant section grew.

Michelin began charging for the guide in 1922, recruited anonymous inspectors, and in 1931 introduced the one-to-three-star ratings that still define fine dining. Between 1926 and 1940 over a million copies were sold, so a company whose core product was rubber became the world's most trusted arbiter of restaurants and hotels.

The case is a pure version of content marketing: the free publication was never meant to make money — it was a distribution channel that increased demand for the real product. It also shows how a marketing asset can escape its original job and become a business and a brand institution in its own right.
