At first "propaganda" referred indiscriminately to both the political and the economic variants; after WWI (née "The Great War") left a bad taste for the term, it was quickly rebranded, with the political version turning into "psychological warfare" and the economic "public relations".

This is still a thing in other languages, Venezuelan Spanish still calls "propagandas" what Anglos call Comercials (I don't think I've heard it in other variations, maybe Colombian Spanish)

Initially, "propaganda" referred to the Congregatio de propaganda fide, the congregation for propagating the faith, established in the 17th Century.
