Don't know about other countries, on my case in France, it was MSN-only, I've never seen anyone with a AIM account ever. I had no idea it used to be popular in the US, I've actually learned that now.

I'd say MSN had the edge over AIM in Scotland too, although the populations overlapped heavily (i.e. most people I talked with had both).
