Not at all. MS Comic Chat was an IRC client that presented the entire chat as a comic book.

I think it's also where the Comic Sans font originated.

# Appears as XENO.

I thought Comic Sans came from Microsoft Bob but according to Wikipedia, Microsoft Bob was the intended use but the typeface wasn't ready in time so it was first release in Microsoft 3D Movie Maker and then went on to other uses like Comic Chat and the Large Hadron Collider.

Not true for entire Europe. ICQ was de facto standard in Czech Republic and Slovakia. No MSN Messanger at all.
