I recall watching Star Trek original run on Friday nights when I was a kid, it was at 930pm or 10pm on NBC and my parents were already in bed.
Then in the 70s they were replayed on our local TV station every day after school, by the 1980s or so I had seen them so many times they were completely boring.
Once in a while one comes up that I still like.
I remember it being on NBC because of the peacock with all the colors in it... we’d just gotten a Motorola Console Color TV, and I was frigging amazed at the fact that yes... there WAS color on TV...
Hard to imagine that in my lifetime, there was black and white TV. Kids now have no recollection of a time before laptops, cell phones, and Playstations...
