I think it was ITV. (UK)
Yep, ITV along with Phantom Empire and King of the Rocket Men.
Phew! I was pretty sure it was ITV but not completely. Thank-you.
Well that’s my recollection from when I was a nipper but this suggests it was more complex than that with different serials being shown on a fre channels at various times.
My main memory is of getting up early to watch the B&W serials on ITV before the proper telly started but it may be I have conflated things into that memory. I definitely wouldn’t have thought they were on BBC 2 at teatime as I recall things like Star Trek TOS being on at 6 and there being a battle to see if we’d watch that or the news. However, the movie serials were presumably cheap filler so different channels presumably filled up time with them at various points.
I will do more digging.
Channel 2
I was so young in the 80’s, I only vaguely even remember watching Flash Gordon, He-Man, TMNT and Teddy Ruxpin while still in the actual 80’s. I definitely do not remember the channel any of them were on.
5, I think, ktla
In New Zealand it was on channel 2. Which is how many channels we had at the time.
We had it on VHS
In NYC I think it was 9, WOR? Or 11, WPIX
In the UK, and no idea until I found this site https://tvrdb.com which allows you to search old TV listings.
It was BBC1.
Got the Blu-ray a few years back. I think the BBC might have cut a few bits.
I saw it in the cinema.
