Via Digg:
 Trends in purchasing habits.
The first graph is kind of interesting for the last column. But not terribly surprising either.
The second graph is simply amazing. The adoption rate of new trends changed completely after the Color TV. Look at a graph like that and tell me you can't understand why the elderly generally have a hard time adapting to new trends and technologies. I think it would be even more fascinating to extrapolate that over the last 1000 years or so. My guess is that the pattern would be consistent going back.
Incredible times we live in. What trend will push that graph even tighter? And will it arrive in 5 years or 50 years?
