The bottom of the article links to the history (individual features) of other IM programs from that era as well like ICQ and Yahoo Messenger.

Yep, early 2000s in the UK and everyone was using MSN. I didn’t know a single person using AIM or ICQ!
I can see why AIM would be mostly an American phenomenon, given it was initially a feature specific to AOL. ICQ…I like to say I’m 10 minutes too young to have used ICQ, everybody who has wistful memories of it were like the seniors when I was a freshman. Yahoo! was the other one; the perpetual alsoran.
