My Godfather owns all of TNG on vhs, I grew up with those. I started on the TOS movies with my parents before I started borrowing the TNG episodes weekly. So yes, I may have been 2 when it went off the air but it's still possible to grow up with this stuff.
I was 12 when I started watching Star Trek in 1975. And I envy the people who had access to all the cool stuff that came out before that
The first Star Trek series I ever started taping on my VCR was TNG. Week after week, trying to scrunch as many episodes as possible per tape (there wasn't any way to program the machine to cut out the commercials; it had to be done manually), year after year...
And now with a few mouse clicks, I could buy all of it on Amazon. It seems too easy, like cheating, somehow...
