A couple examples of what I'm talking about:
Apologies, as I realize this is a bit of an broad question. Feel free to address a subsection or specific type of video if that makes more sense or aligns with your knowledge or whatnot.
Essentially though, I'm trying to get my mind around the how/why of the seemingly massive body of PSA type content that seems to have been produced. Videos about how to be a good homemaker, how to succeed at work, hygiene, yard care, how various technologies worked, etc.
I thought perhaps it just seems more prevalent because they've been collected on Youtube and made more visible. But these videos and their distinctive style of narration have been a trope/meme for as long as I can remember.
TV Shows riffed on them. Disney made entire Goofy cartoons that were just spoofs of these videos. e.g., "How to Fish"
As best I can tell, the public has been plenty familiar with these films for decades and decades. It seems to imply that these videos were a pervasive thing at some point.
But as a 40 something American, I can't recall ever being shown one of these videos in an "earnest" way. e.g., Something other than a collection of found footage, or other situation where they've been repurposed from educational to entertainment content.
I can put some of the pieces together, but can't seem to make a coherent picture of the whole situation. Many seem to be funded by industry to promote their product. Others by various government agencies to promote... seemingly anything. Agricultural practices, kitchen design, industrial knowledge, civic topics, you name it and there seems to be a video for it.
It's easy enough to see why those entities would want to promote these things. The usefulness of video as a educational medium is pretty straightforward.
But it falls apart when I try to figure out what happens after the video is produced. How were people being exposed to them? Were they used as movie trailers? Could I have turned on my TV and just watched PSA's? Would I have shown up to work one day and the boss says "Hey, we got a new video from GE, let's see what they're up to"? Were the videos intended for internal or external distribution? Did salespeople just show up and say "I'd like to setup a projector..."?
