I will politely counter that I do remember a period in the 90s where DS9, TNG and Voyager were all alive and well in the peak pop culture consciousness at the time. Along with a plethora of comics and novels.
Though, I will counter myself that, that peak was followed by Enterprise a few short years later, which lead to the slight death of the franchise. So all of that previous media could have had a disastrous effect, ultimately (much like now, potentially).
