[Avodah] "Hashem" as God's name

[Moshe Y. Gluck]

R' Yonatan Kaganoff:
At this point the use of "Hashem" to refer to God is fairly ubiquitous in
English speaking Orthodox circles.
 
Does anyone know when this began?  And when it became the de facto way of
referring to God?

I'm not sure why you think that this is recent or limited to English
speakers, but Kitzur Shulchan Aruch (6:3) already says to say Hashem.
