Changes creates innovation; innovation creates a need for change.
If you follow it from a historical point of view, it becomes obvious that innovation follows change.
The myth of spontaneous innovation creation, in which an individual (through his own brilliance) creates something so revolutionary that the world changes, isn't how innovation becomes accepted into the mainstream. The way an idea becomes innovation is by filling a need created by change. Without the change the idea just stays an idea - regardless how brilliant it is.
What innovation does create is a need for change. The classic example is the automobile.
The automobile had existed for decades before it was accepted into the mainstream. What eventually turned it into a necessity was a growing middle class and it's desire for greater mobility. Without this middle class the automobile would have remained a plaything of the rich.
Once it became ubiquitous the automobile gave the country options not previously available. These options created changes in disciplines such as architecture (suburbs), business logistics (door to door deliveries), and leisure (car camping). Then those changes created the need for further innovation.
