Here is something interesting.
Socionomics.net posted a two part article about national mood, measured in Dow Jones “bull” and “bear” markets, being reflected in the content of cartoons. In a nutshell, when the markets are up, cartoon content is more positive. When markets are down, content becomes more serious and cynical. Here are some of the graphics
The articles are not difficult reading, and offer some interesting perspective on animation history. And it makes sense. When life is good, people do not want to question it, they want to enjoy it. When life is difficult, people like to see stories about others in difficult situations, because they can relate to it.
I particularly like this graphic, although I’m not sure I agree with the “art” category.
