Evangelical societies also did a big business with "holy" slide series.
Ed Liesegang was the most successful maker of projectors/lenses in Germany - and sold slide series.
I have even seen a slide series by Liesegang showing lens production at one of his lens maker rivals in Germany!
These are quite common - there are special categories of the animated slides and the usual erotic variations for all-men audiences (I'm told!).
