This was in the early/mid 90s or so I'd hazard to guess. I've only seen it on PCs.

It was often the most fun application in an elementary school's computer lab. As far as I know it was never officially bundled or anything, but just a popular program. I also had it on my computers at home because both my parents were in graphic design and used Corel Draw for work, and my dad was a bit of a computer geek.
