I don't know if we have ever discussed this. I know most of grew up watching TOS but how many of our parents also watched ?
My dad and I watched when the show was on channel 50 at 6pm. We would always leave it on during dinner - drove mom NUTS.
I don't recall ever watching the original broadcast in 67 since I was just a wee lad. Heck, I can barely remember what happened yesterday.
My brother of course watched, and my step-father from time to time enjoyed it. My mom would watch at rare times, but she did help with our early costuming!
My dad always watched and still does. He's basically the reason I'm into sci fi at all.
