<P> Moore's law is the observation that the number of transistors in a dense integrated circuit doubles approximately every two years . The observation is named after Gordon Moore, the co-founder of Fairchild Semiconductor and Intel, whose 1965 paper described 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 . In 1975, looking forward to the next decade, he revised the forecast to doubling every two years . The period is often quoted as 18 months because of Intel executive David House, who predicted that chip performance would double every 18 months (being a combination of the effect of more transistors and the transistors being faster). </P> <P> Moore's prediction proved accurate for several decades, and has been used in the semiconductor industry to guide long - term planning and to set targets for research and development . Advancements in digital electronics are strongly linked to Moore's law: quality - adjusted microprocessor prices, memory capacity, sensors and even the number and size of pixels in digital cameras . Digital electronics has contributed to world economic growth in the late twentieth and early twenty - first centuries . Moore's law describes a driving force of technological and social change, productivity, and economic growth . </P>
