On April 19, 1965, Gordon Moore, then head of R&D at Fairchild Semiconductor (and later co-founder of Intel in 1968), published an article in the anniversary issue of "Electronics" magazine titled "Cramming More Components onto Integrated Circuits."
One of the key ideas in the paper, later known as "Moore’s Law," stated: "The most cost-effective number of transistors on a chip doubles every year."
