Created by by Intel co-founder Gordon Moore in 1965, the rule of thumb known as Moore's Law originally called for the number of transistors inside an integrated circuit to double every year. In 1975, the Law was revised. That year, Moore said that the number of components inside an integrated circuit would double every year until 1980. After that, the doubling would take place every other year. The improvements and innovations in the performance of mobile tech devices, including the Apple iPhone and Samsung Galaxy devices, depended on this Law continuing to be in force.
