The plot below shows the price of TVs across Best Buy’s Black Friday ads for the last 25 years. The units are “dollars per area-pixel”: price divided by screen area times the number of pixels (normalized so that standard definition = 1). This is to account for the fact that bigger, higher resolution TVs are more expensive. You can see that, in line with the inflation chart, the price per area-pixel has fallen by more than 90%.

Yay! Now do computer ram from 1980 to 2020 before Ai was involved, and discuss size per dollar. You wanna do CPUs or hard drives next?
