There are several "holy grails" in British TV history.
Lost Doctor Who episodes are one of them. Dad's Army also has lost black and white episodes (the colour ones have been repeated ad nauseam all my lifetime).
I can think of a few others. Scotch on the Rocks was a political hit piece written by Douglas Hurd showing an armed Scottish uprising along the lines of Northern Ireland. It was supposed to frighten people away from Scottish nationalism, but ended up causing copycat incidents. It vanished shortly after being broadcast probably because of its unintended effects.
The ultimate would be some of the pre-WW2 television broadcasts. Most of these were broadcast in the London area and practically nowhere else. Almost no one had recording equipment back then and they were often broadcast live.
You're correct but as Uvix has said, BBC Enterprises made film copies for overseas sales before the original tapes were erased.
The earliest episode to survive on its original videotape is Ambassadors of Death episode 1 from 1970. None of the original 60s tapes still survive, though I believe there is at least one tape that we know used to have Doctor Who on it but which now has another programme.
The earliest episode to survive in its original medium is possibly The Dalek Invasion of Earth episode 5 (The Waking Ally). That's because, while this was shot on electronic studio cameras as usual, there were no videotape machines available to record.
Instead the output of those cameras was telerecorded straight to 35mm film. AIUI the negative of that telerecording still exists.
The BBC used a kinescope much longer than the US. (A kinescope recorded TV to film.)
The US pushed a lot harder than Europe for videotape because kinescopes dropped frames off of American 60i frame rates, but worked really well for European 50i frame rates. Thus the BBC continued to use kinescopes for a long time.
I was afraid this would never happen again. Two very good episodes, too.
I just pray that we'll get to see a few more Troughton episodes. He's the doctor that set the standard that all future doctors followed, yet the least known because the moronic BBC wiped basically his entire run, and now we only have about half of it.
Tom Baker was "my Doctor" because he's the one who made me love the show when I was a kid, but Troughton (and Zoë and Jamie) are my favorite era.
edit: Zoë and Jamie are from way back when the companions were expected to be useful, before Sarah Jane. Zoë was better at math than the Doctor; imagine them doing anything like that now.
I remember wanting to love Dr Who even before it was broadcast. The TARDIS was great, but the first series was disappointing. Like so many others, it was the first sight (and sound) of a Dalek which vindicated my hopes.
I think Doctor Who was finding its feet in the Hartnell era and it was Troughton who really first defined the character to what he became later.
In the Hartnell era, the Doctor was a grandfather I think, looked old (although Hartnell was much younger than he appeared, thanks to the war etc) and seems to have been human.
There are production stills that are used like a slide show and combined with the recorded audio.
Certain episodes have been reconstructed using animation such that the basic scene blocking and events are played out alongside the recorded audio.
It could recreate missing episodes using the extant episodes. That's something worthwhile doing until someone finds them. It's not creating a complete new series.
People want to find the missing episodes because of their historical value as actual human artistic creations, and not because they want to watch a thing that looks like an old missing episode.
There would be as much value in an "AI-recreated" missing episode as there would be in taking the audio of a modern episode and using AI to create a new video track for it.
It's strange for formerly lost media to get a whole news story about it. This should, but still strange.
Hope more are found sooner than another 13 years from now.

Why should that be strange?
Film cans? I thought the whole reason the series was missing was because it was shot on video, and then the tapes were wiped after shooting?

Recording over another recording does not completely erase the other. I wonder if it could be recovered.
It has been suggested numerous times, but the BBC didn’t just record over the top - the tapes were erased with a degausser before reuse.

That era of companions was a response to the eras before then when companions were expected to just look pretty and scream on cue.
Companions are still useful, they just bring different skills to the Doctor (humanity?).

Perhaps the doctor meant for these to be lost and not found, or that the daleks was afraid of them?

We have all the voice recordings, feed that into AI along with the extant episodes and it should be able to regenerate (geddit?) the missing episodes.
Somebody spent a small fortune trying this a while ago with disliked results https://nypost.com/2025/04/13/entertainment/ailing-doctor-wh...
Do we also have stills of all the episodes? Or only audio?

Feels a bit like Jurassic Park
The risk of the episodes going wild and kill lawyers seems minimal though.
Then what is AI even good for? :(
Risk or benefit?
From a utilitarian pov yes. But that's completely missing the artistic point. Why shoot a film when you could just feed the script into an AI?

Even if it's motion comic level animation, it'd still be nice to see combined with the audio recordings.
