The first commercial microprocessors were simple but revolutionary small computer and design magic. Unlike the individual integrated circuits that preceded them, microprocessors were standalone computing devices. Before the introduction of the first commercial microprocessor ̵
The first commercial application of this revolutionary invention was practically a calculator. Even more remarkable when using the microprocessor for the first time is that the company was responsible for its existence behind the computer that powered it. In 1969, Busicom, a Japanese pocket calculator company, approached Intel with a calculator design designed to maximize computational power while minimizing the number of integrated circuits required.
Engineers from both companies began to work on the design, with fewer and fewer individual integrated circuits. While working on the project, Intel engineer Ted Hoff created the prototype that gave rise to the Intel 4004. Within a decade of this first commercial exploitation, the microprocessor had found its way into everything from handheld games to rocket control systems, and a technological revolution triggered
