How Many Schools Benefited From These Narratives?

I remember growing up, as a lot of us do, seeing a lot of slightly dated instructional videos in health class. And whenever my school would try and teach us about issues, they often farm it out to a video from the 80s. I wonder how many of those were after school specials or the kind of programming that came on as that became popular. How much of this work, like how many schools benefited from the existence of these narratives? It's funny because I actually remember watching one that in retrospect speaking of the empathic nature of them, I found surprising and great Because I was used to making fun of them.
