From the informal version of the Moore’s Law:
Moore’s original statement that transistor counts had doubled every year can be found in his publication “Cramming more components onto integrated circuits”, Electronics Magazine 19 April 1965. Moore slightly altered the formulation of the law over time, bolstering the perceived accuracy of Moore’s Law in retrospect. Most notably, in 1975, Moore altered his projection to a doubling every two years. Despite popular misconception, he is adamant that he did not predict a doubling “every 18 months”. However, an Intel colleague had factored in the increasing performance of transistors to conclude that integrated circuits would double in performance every 18 months.

Same price, twice the capacity. Roughly 17 months and one financial crisis later and the price per GB is almost exactly two times lower. Incredible.
