Wikipedia Version Control – Find When a Phrase Was Added

mediawikiwikipedia

Is there any way to find when a specific word or phrase was added to a Wikipedia page? I want to find a way to obtain the first page that contains a match of a specific phrase (for example, the first occurrence of <ref>webapps.stackexchange.com</ref> in a page's revision history). (Manually searching through a page's revision history would be extremely tedious, so I'll need some kind of automated solution.)

There is a tool called WikiBlame that lets you do exactly that: you enter a page name and a phrase to search for and will point you to the edit that added it.

It's also linked from the History page of every page on the English Wikipedia (as “Revision history search”).
