My son, who’s now 11 years old, used to have iA’s Web Trends Map v4 on his wall. It was produced in 2009, when he was two:

iA Web Trends Map 4 (2009)

I used it to explain the web to him, as the subway map was a metaphor he could grasp. I’d wondered why iA hadn’t produced more in subsequent years.

Well, the answer is clear in a recent post:

Don’t get too excited. We don’t have it. We tried. We really tried. Many times. The most important ingredient for a Web Trend Map is missing: The Web. Time to bring some of it back.
Basically, the web has been taken over by capitalist interests:
The Web has lost its spirit. The Web is no longer a distributed Web. It is, ironically, a couple of big tubes that belong to a handful of companies. Mainly Google (search), Facebook (social) and Amazon (e-commerce). There is an impressive Chinese line and there are some local players in Russia, Japan, here and there. Overall it has become monotonous and dull. What can we do?
It's difficult. Although I support the aims, objectives, and ideals of the IndieWeb, I can't help but think it's looking backwards instead of forwards. I'm hoping that newer approaches such as federated social networks, distributed ledgers and databases, and regulation such as GDPR have some impact.
