Why the Michelin Guide exists

The year is 1889 and your fledgling tyre company is looking for clever ways to sell more rubber. Problem is, there are only 3000 cars on the road in France at the time. So, what do you do to encourage those 3000 car-owners to use their vehicles and thus wear out their tyres? If you’re the Michelin brothers, you invent the Guide Michelin, of course.
