Anime, you've changed! To be honest, the look of it is always changing. Styles and fads suit each age, so let's see how anime has evolved over the past few decades.
On 2ch, a commenter uploaded the following image below, which Kotaku has translated into English:
I quite like this as it gives a good, nuanced look at just how anime has changed since the 1990s.
Elsewhere in the same thread, others uploaded images that also show how anime styles have grown. You might have seen them before, but if not, have a look.
I wonder what anime will look like 30 years from now.
