In 1965, Moore was working as the Director of research and development (R&D) at Fairchild Semiconductor. He was asked by Electronics Magazine to predict what was going to happen in the semiconductor components industry over the next ten years. In an article published on April 19, 1965, Moore observed that the number of components (transistors, resistors, diodes or capacitors) in a dense integrated circuit had doubled approximately every year, and speculated that it would continue to do so for at least the next ten years. In 1975, he revised the forecast rate to approximately every two years. Carver Mead popularized the phrase "Moore's law." The prediction has become a target for miniaturization in the semiconductor industry, and has had widespread impact in many areas of technological change.
