• What would become known as "Moore's Law", that computing power would double every two years, was first suggested by Gordon Moore in an article in Electronics magazine, titled "Cramming More Components onto Integrated Circuits". "The complexity for minimum component costs has increased at a rate of roughly a factor of two per year," he wrote. "Certainly over the short term this rate can be expected to continue, if not to increase. That means by 1975, the number of components per integrated circuit for minimum cost will be 65,000. I believe that such a large circuit can be built on a single wafer." Within three years, Moore would become co-founder of the transistor and microprocessor manufacturer Intel, and as transistors became smaller, the size of a transistor would decrease over 40 years from {{Convert|0.5|in}} by {{Convert|0.25|in}} to a size where they were "so small that millions of them could fit on the head of a pin."{{cite book |first=Brett |last=King |author-link=Brett King (businessman) |title=Bank 3.0: Why Banking Is No Longer Somewhere You Go But Something You Do |publisher=John Wiley & Sons |year=2012}}{{cite book |first=Vivek |last=Kale |title=Guide to Cloud Computing for Business and Technology Managers: From Distributed Computing to Cloudware Applications |publisher=CRC Press |year=2014 |page=521}}
