Random Post – Words Usage of Pub and Inn

As an another irrelevant aside, I just noticed this on Google Ngram, which is how frequently the words ‘pub’ and ‘inn’ have been used in literature over the last two centuries.

It’s no surprise to me that the word ‘inn’ used to be used much more frequently when the word ‘pub’, but I’m puzzled how it is now used more frequently in writing once again.
