Phrase: it has become the general practice that

[Alimysoul]

can anyone explain to me please
(it has become the general practice that)

[Jamie (K)]

Everybody is doing it lately.

In the 19th century, it was common for teachers to beat students in American schools. In the 21st century, the teachers never touch the child.

So...

It used to be general practice to beat school children to discipline them, but since then it has become general practice not to touch them.

Yes, "since then" means "from that time until now".
