The American chart has the overtaking in the 1940s. I can't help but wonder if there's not a sort of social cause... like, perhaps, the increase in higher education (democratization of the academy)--although that starts in the 1940s and you'd think that it'd lag that, then. The Depression? Jazz-age literary trends making people used to things? Migration leveling dialect?

Pity I have to go back to ancient astronomy as opposed to working on this. ;)

... Although before I do, that it's in the 1960s is rather telling, i'n't it?
