The one show I could watch the repeats in the summer during the 80's and in 2018 and 2019 the shows on Blu-ray

I also bought the soundtracks and any collectables that was Miami Vice related.

Trek TOS.

Used to watch reruns with my brother every night during the 70's on WPIX (?) growing up in Queens.

The Brady Bunch

The Six Million Dollar Man
Miami Vice

This was mine as well.

Probably not in the dubbed English versions. But in the original uncut series, Kagaku Ninja Tai Gatchaman, Berg Katse's true identity was revealed near the end. He / she is a genetically modified human, in the hands of Galator's Leader X, by fusing of fraternal twins while they were still in the womb of their mother. So Berg Katse can change appearances at will.

My problem was that I also watched "Batman", which (at some point in it's original run) ran opposite LIS on Wednesdays, so I'd switch back-and-forth.

For me it was the Smothers Brothers show. Unfortunately, it caused a classic generation gap battle in my house, since my dad was a big Bonanza fan, and they were on at the same time.

Hunter

Everybody did that. Part 1 of Batman was also Wed at 6:30. I just sat on the floor right in front of tv constantly switching back and forth. It's one of those baby boomer things like "running home from school to catch the end of Dark Shadows"

Get Smart/Mission Impossible

Not counting shows that were reruns or childrens' shows, I would guess it would be Buck Rogers in the 25th Century and The Dukes of Hazzard, which came out the same year. Buck rogers was a movie first so I would have seen that before The Dukes of Hazzard which I didn't start watching until the fall of '79 and maybe a short while after that as I didn't start watching that until my sister got me to wtch it. So it would have been a few weeks or months after Buck Rogers.

Hard to pinpoint one show - I vaguely remember following shows like Love Boat, Fantasy Island and Dukes of Hazzard.

if I remember right In the Asian version he was born with both Male and Female sides and switched back and forth. In the American version I think they just made it two different characters

Little House on the Prairie

I think LA Law was the first "adult" drama I started watching on my own (and not because someone else in the house was watching it).

I had look at tv shows during the year when I left home just to be sure it was something that was totally my choice.
