When did the modern conventional formatting of Biblical citations become standard?

Virtually all resources published these days make Biblical citations in the same way: "John 3:16" with the chapter and verse numbers in Arabic numerals, separated by a colon and with no other punctuation. However, when I read books printed a long time ago (maybe from 100 years ago or so), I find many other ways of referencing Biblical passages. As some examples: > "John iii. 16" - used in this 1885 translation of 1st Clement and throughout that collection of the Ante-Nicene fathers. > > "John 3. 16" - used in the 1917 printing of the Scofield Reference Bible . > > "John, iii, 16" - used in the 1912 printing of the Catholic Encyclopedia . However, there is not such diversity of citation styles among more recently published works. When and why did the modern convention become standard?
