As Fiorella used to teach her students, there are four major dialects of English: American, British, Indian, and Australian. And, like tectonic plates, these dialects are drifting further and further apart each year. Eventually, they'll be four separate languages.

Yes, several sub-dialects used to exist within these four dialects, but we're all talking more like broadcasters and movie actors now.
