For companies today, “breakthrough innovation” has become something of a holy grail. But achieving a breakthrough – even a truly momentous one – doesn’t guarantee commercial success. Some products that represent great technological advances never gain a profitable place in the market – they’re too good for this world.

The Concorde’s unhappy fate, I argue, tells us something important about how easy it is to misread the dynamics of both technological progress and marketplace change.
