I'd have to go for the 90's.
While I first discovered Trek in the 80's, with TNG, I was only a youngling, not even 10 years old and we only had one TV in the house. My dad did watch it, but not religiously, and would often switch channels, see it was on and continue watching from wherever the episode was up to and if the particular episode didn't interest him, he'd flick back to the news or something.
Also it was shown around 6pm on BBC once a week, and often clashed with the time we were sitting down for dinner after school / work.
when I was 13 (in 1993) I finally had my own TV in my room, so was able to watch it - so long as we weren't having dinner, but a year or so later we got cable for the first time, and I had a box in my room, and TNG was shown daily on Sky 1, (2 or three times a day) and later DS9 and Voyager aired new episodes Monday nights at 8pm so I was able to soak it all up.
the 2000's only really gave us Enterprise, and the first Kelvin movie so there was nothing to make it stand out.
The 2010's have been good though. 2 more movies and Disco - and I don't care what the naysayers say, I've loved both the Kelvin movies and Disco, plus short treks - but
