It is not a physical or natural law but a technological trend that has been remarkably long-lived. Originally formulated in 1965 at the dawn of the electronic age, the popular rendering of Moore's conjecture is that the number of components in an integrated circuit will double every year (Moore, 1965). This means in theory that the processing or computing capability of the integrated circuit doubles every year as well. This prediction was later revised by Moore to doubling every two years (other reformulations of the law state that the doubling occurs every 18 months).
