The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

Wipe Out: When the BBC Kept Erasing Its Own History
I'd be surprised if they even taped it that far back.
taping at a corporate level didn’t exist until 20 years after the OP’s show aired – and another 20 years until consumer taping entered the picture
even then, BBC had no compunction about continuing to erase stuff – only relatively recently, they’ve started to realize just how bad a decision that was and have been begging for copies from people who taped shows to VHS – which itself hasn’t gone over too well because BBC also has a reputation of prosecuting home tapers, so without a promise of amnesty, no one’s coming forward …
Given that reel to reel tape recording of television didn’t begin until the 1950s I’m going to say they didn’t. The only way they recorded back then was pointing a film camera at the TV, but this couldn’t really be used for rebroadcast, so I’m guessing a lot of these early TV broadcasts weren’t recorded.
The article cerement linked indicates it was likely a live broadcast.
They didn't.
Early days of television was the wild west. They didn't know what to do so they basically took stage and radio concepts and adapted them to TV. That's why so much early TV was vaudeville-esque variety shows.
But they didn't even have a means to record if they wanted to. Everything was live. Not even a delay.
There was a podcast episode about this recently, and Howdy Doody...I think it was 99PI.
