Google Scholar was getting me nowhere, which is why ended up posting here, as all the articles it was turning up were about the production and distribution processes, where my question goes to public reception and subsequent reverberations in later visual arts.

The switch isn't my interest. The generational imprinting is. Hence the home video angle sounds promising. For instance, have a very distinct recollection of a throwaway gag scene, in latter era nostalgic animated programming, depicting a representation of the live action martial arts broadcasts of the time, with even more exaggerated elongation of bodies on the vertical. This being a semiotic pastiche immediately recognizable to those of a certain generation.

Last century Usenet will be useful to dig into. Though it may be a bit too early for the trends to even have appeared. Folk who grew up watching that stuff had to become established in media industries for the influence to begin manifesting in new media.
