Moore's Law

"The basic rule--which states that the number of transistors on a chip doubles every 24 months--has been the guiding principle of the high tech industry since it was coined by Intel co-founder Gordon Moore in 1965.

It predicts technological progress and explains why the computer industry has been able consistently to come out with products that are smaller, more powerful and less expensive than their predecessors--a dynamic curve that other industries can't match. "


Absolutly boggles the mind doesn't it? I still fondly remember my Commodore 64, plugged in to the black and white TV in the spare bedroom.
