They didn’t make Publisher, it had been around for a few years before they acquired it.

At the time (early 90’s), DTP was growing, fast. Publisher was stupid cheap compared to Aldus and Quark and could do all the day-to-day stuff for a fraction of the cost (and faster).

I was using all 3 at the time, and my go-to was Publisher as it was easier, and way faster on the hardware then.

I’d use PageMaker for multi-page, ongoing docs, but a single page? Publisher.

MS acquired Pub around 1995.
