In 1965, Moore examined the density of transistors at which cost is minimized, and observed that, as transistors were made smaller through advances in photolithography, this number would increase at "a rate of roughly a factor of two per year".
Godine 1965 Moore je ispitao gustoću tranzistora pri kojoj je trošak minimiziran, i primijetio da će, budući da su tranzistori postali manji kroz napredak u fotolitografiji, taj broj porastao na "stopi od otprilike dva puta godišnje".
