Oh, Google, say it ain't so ...
The Google Books Ngram view of the situation doesn't give much support for why their search algorithm should respond as it does. But the Google Books dataset ends at 2008, and those data are in any case from books, so maybe there's been a spike in the number of people online typing in the
wrong new version the past few years.
[Added] That wasn't very bright of me. Try this ngram view instead. Worrisome trend!
