It's very strange to me how small Spanish is there.
Second language in the world by native speakers, piracy being effectively legal in Spain (non commercially), and so on.
Very weird.
Only in Spain there are 3k publishers. Argentina has 1k publishers.
And then we have huge amount of books published in spanish by Penguin Random House, Scholastic, Springer, etc.
It's because some books are not categorized as Spanish. They are just under a publisher name. For example, search for "Don Quijote"
Spanish is second largest by people but not by revenue
Piracy of anything other than live streams of La Liga games... For those, Spain shuts down whole IP ranges and cripples the Internet at large while the game is live.
