Many years ago, the Ford Motor Company wanted to tell American motorists that they sold more convertibles than did any other automobile manufacturer. They could perfectly well have said: ‘America’s bestselling convertible.’ Instead they ran a headline that read: ‘The only convertible that outsells Ford.’ And the picture was of a baby-carriage. That is a kind of humour; and it’s almost a joke. It certainly depends entirely on a contribution from its audience for the communication to be complete. But the contribution is a small and pleasurable one, well within the capacity of anyone in the market for a car. And what could have been a piece of self-congratulatory manufacturer’s so-whattery became engaging evidence of confident leadership. The point had been seen.
