While Moore did not use empirical evidence in forecasting that the historical trend would continue, his prediction held since 1975 and has since become known as a "law". In 1975, looking forward to the next decade, he revised the forecast to doubling every two years, a compound annual growth rate (CAGR) of 41%. The observation is named after Gordon Moore, the co-founder of Fairchild Semiconductor and Intel (and former CEO of the latter), who in 1965 posited a doubling every year in the number of components per integrated circuit, and projected this rate of growth would continue for at least another decade. Rather than a law of physics, it is an empirical relationship linked to gains from experience in production.

Moore's law is an observation and projection of a historical trend. Moore's law is the observation that the number of transistors in a integrated circuit (IC) doubles about every two years.
