I just had a look at the all Winter games medal table:

The winter Olympics are a very European event. Nearly all European countries have an entry in the all games combined medal table, the two largest missing are Greece and Ireland.

Outside of Europe (well, I count to Europe also all former USSR parts) the only ones ever having won winter medals are the four obvious (European plantations): USA, Canada, Australia, New Zealand and four countries from the far East: China, South and North Korea and Japan.

Total: 8 countries out of Europe and 30 European countries have ever won winter medals.

The most surprising (on a purely linguistic level) omission from the overall medals list is Iceland.
