Where 1965 fits
Why 1965 is special
Gordon Moore observed that the number of components on a chip had been doubling roughly annually and predicted it would continue for a decade. It held for about fifty years, was revised to two years along the way, and functioned as an industry target as much as a prediction.

Noyce's manufacturable integrated circuit of 1959 is what made Moore's 1965 observation about component counts possible to sustain.

Moore observed component counts doubling roughly annually and forecast a decade of it. Revised to two years, it held for around fifty — partly because the industry treated it as a schedule to meet rather than a trend to observe.
