I would have expected it to spread through the English speaking parts of the world (particularly through Australia, England and USA) but I was surprised to see the list of countries names in the statistics this year.
Have a look for yourself.
I see there is a huge amount of traffic that falls into the 'Unknown Country'* category, so who knows there could be many more countries than those already listed ( a few more at least).
If you are interested you can compare the visits this year with the previous year here.
