I don't know of any current reliable book or other resource that examines the evolution of both the engineering and the hifi market at the same time, with two exceptions.
The first is this timeline from AES:

The second and best example I know of is
Frederick Vinton Hunt's
Electroacoustics from 1954. It's a rare book whose 90-page introduction examines the whole of the development of electrical transduction from the invention of long-distance communication using electricity (telegraphy) to the microphone and speaker. All of this with exceptional understanding and presentation of the underlying principles of development. There are a few pages about the development of hifi but they aren't written with the sort of detail that we would want, as in extensive looks at companies, models, their specs and so on.
The issue as I see it is that we don't know our own past with any sort of clarity. I think that affects everyone in the industry, us included, with a deep lack of perspective. Hunt himself started his book by pointing out that he spent much of his time doing historical research in the patent office because there was very little other written material he could work with. I could imagine us repeating that work with similar resources like old websites, manuals, advertising catalogues and more patent hunts since, like him, we have nowhere else to look.
