Moore's Law
In 1965, Gordon Moore published a 4-page paper entitled "Cramming more components onto integrated circuits"[1], where he predicted that the number of components in an integrated circuit will increase by a factor of two every year, as shown in Fig. 1. Note that he based his extrapolation on just 4 data points!

Why is this paper and the graph in Fig. 1 important? Gordon Moore's prediction, also known as Moore's Law, has reflected and, more importantly, driven the steady and rapid progress in computing technology[2]. Thus, satisfying Moore's Law has become the goal instead of being merely a prediction.
Evolution of Complexity
As Gordon Moore predicted, the cost and performance advantage of putting more and more devices into a single integrated circuit (IC) led to the rapid increase in circuit complexity. One convenient indicator of circuit complexity is the number of transistors contained in a single IC.
