Technology Adoption ~ A Century of Diffusion of Innovations!

I most recently ran across this really lovely graph about the adoption of new technologies since 1900 in the United States on the Visualizing Economics site (plus here's the NYTimes source; and, also the creator's website, Nicholas Felton's feltron.com)... What's especially interesting is looking at both the pace of adoption and whether it's gotten faster, and at decomposing the adoption to the level of multiple generations of a product. For instance, 8086 PC's versus 286 versus 386 and 486, etc. Or different videogame consoles, etc. Even more interesting is seeing this century-long diffusion plotted for the worldwide population of Earth, not just the rich US.
