Before smartphones, television, etc, language was a much more significant source of entertainment in itself, and so people invested much more time in word play, or employing more descriptive and emotive vocabulary and phrases. I think this is why, for example, not too long ago you typically saw more colorful language in rural areas, especially before television became such a ubiquitous past-time, but after more modern entertainment like film became common in the cities and suburbs. This seems still somewhat true in less developed areas around the world, where "back country" folk sometimes have a peculiarly rich vocabulary and manner of speech compared to their counterparts from more urban, modern areas.
Imagine if we spent (intentionally or unintentionally) all the time we spend today learning to identify and applying pop-culture references to instead improving our vocabulary or using more expressive speech patterns. Or to put it another way, before mass consumer popular culture, expressive speech was the popular culture--stories, jokes, songs, turns-of-phrase, or just gossiping, but unlike those things today you had to add the flourish.
Maybe it's just all in my head, though.
