“Much in the same way as children in your day made crystal sets.” I played with one in my 1960’s youth, fiddling with the cat’s whisker in an attempt to get a semi-decent signal. How many kids today even know what a crystal set is?!

The Viziscope privacy issue was the focus of a story by either Issac Asimov or Ray Bradbury. It was based around a historian wanting access to the machine (which was closely controlled) and after a lot of issues the historian makes his own and it’s pointed out by the government that “when does history actually start” (so a millisecond after something has happened, it’s “history”) and boom… there goes all privacy.

I always take this as an explanation of the Fourth Wall break in Feast if Steven. He knew The Time Lords were spying on him so decided to wish them a Merry Christmas

Whoever wrote this is an insane genius. Best thing I’ve watched in ages 👏

The ending of this story clears up a line from The Sarah Jane Adventures story: "Death of the Doctor". Matt Smith's Eleventh Doctor tells Jo Grant that he never came back for her, because he couldn't find her as she travelled all over the world all the time. Then he lists things she has done, but how would he know if he wasn't able to find her. I believe now that he tracked down Jo on the space time visualizer and saw her achievements that way.

Thanks for another fascinating episode. I do think we can all get over-obsessed with internal consistency at times, even though those moments of seeing behind the curtain when it breaks down are fascinating and instructive. With assorted writers on a long-running TV series it's difficult to achieve internal consistency even on the most mundane soap opera level. As soon as you introduce Science Fiction it becomes almost impossible. It would have required a concerted central effort and the willingness to ditch great story ideas simply because they contradicted a throw-away line of dialogue from an episode broadcast months previously. We would all be the poorer if that had happened. We also always have to remember that the average viewer of the 1960s was expected to see an episode once and probably never again. The chances of them being able to pick up inconsistencies with an episode they saw weeks ago was slight and the chances of them being able to check their recollection even more remote. As with the wiping of tapes, unless we try to understand the position of the people concerned at the time then we are selling them, and us, short. No one at the time conceived that people would want, or be able, to pore over populist TV episodes over half a century in the future. They were simply trying to produce a well-crafted, intriguing and entertaining diversion for a Saturday evening. I appreciate the fact that you are always reminding us of that human factor. The fact that we still find such TV productions fascinating and worthy of study is a tribute to the maker's skill and imagination but, for them, an entirely unexpected side-effect.

Great to see the series return and I think this is one of the best episodes yet. I particularly liked how you were able to move from discussing fine details of the prop’s design and construction, to how those aspects relate to the series’ mythology.

Finally, ive been waiting for so long, recently been rewatching your stuff recently, and its all as infinitely funny, gripping and impressive as i remember, welcome back

clearly ian and barbara's fascination came from the fact that Dr. Who built a time-travel-related device that actually can find its intended destination for a change :P

It is really nice to have ya back after 2 years although this video was so well made it's like you never left.

Wonderful as usual! I didn't even quite realise it was two years since the last one, just feels like a couple of months ago!

I LOVE The Chase, one of my favourite Dalek stories (possibly my #1)

when the world needed him the most, he returned :)

I can't say how delighted I am that you are back.

Fantastic video, amazing work on some of the ambitious visuals! Very entertaining and insightful

I’m happy to see another of these amazing videos! Also I Love The Chase Clips giving a beautiful 1080p up scale treatment that deserve to be part of the Season 2 Collection Boxset when it comes out. Amazing work from You and TheMindRobber. Also *Banana!*

Today is now a great day, THE Dalek is back. Edit: I was eating a banana watching this a second time.

Also, thank you for the fascinating information between The Chase and Asimov's Caves of Steel series. They're some of my favorites and I never new Nation wrote adaptations of them or that they were shown on the BBC. It would be amazing to see those if they hadn't been lost. Who knows, maybe some day more lost footage will be found.

It's possible that the STV was connected into the TARDIS 's systems, which would then, in turn be, connected into the Matrix. Therefore it is quite possible that the TARDIS's telepathic circuits were used to guide the STV to the exact point in space-time the user wanted to see. OK, this idea might seem slightly "Banana"s at first sight, but it does make sense.

Welcome back! Love this idea of a “toy” that really changes perception of the lore. Keep an eye out for the Bananas!

I like the thumbnail - she was the best companion. What a fantastic pair they made.

There's an episode of classic sci-fi anthology series Out of the Unknown that covers the issues raised by having something like the Space-Time Visualiser. The episode is "The Dead Past", based on an Isaac Asimov short story of the same name, and it's about a group of people trying to figure out why the government is so obstructive when it comes to the use of a device called the Chronoscope, which allows viewing of any past event. It's only towards the end that the characters truly realise what it means to even have such a device, and that the government was genuinely working in everyone's best interests by suppressing it. But it's too late: guides on how to make it have been sent out into the wild and now anyone can build one, effectively destroying privacy forever now that anyone can view anybody at any time. Another interesting couple of links back to Doctor Who: Terry Nation wrote an episode for it, adapting The Fox and the Forest by Ray Bradbury. Sadly it's now deleted. Another story mentioned in this video, The Naked Sun, also got adapted into an Out of the Unknown episode. Oh, and BANANA.

Finally they return! An incredible video as always. I eagerly await future installments (perhaps something on the Barnado’s props?…)

Great video. So much work has gone into this - it's much appreciated for us to enjoy. It's great having a new episode on the channel 🙂

I’m so glad to have another video on this great channel! Terry Nation is such an amazing writer I’d have loved to see how he would’ve written stories with the bigger budgets!

I came for the thumbnail but stayed for the content, which I found thoughtful, creative and insightful.

Great Video! I wouldn't get too confused about our solar planets on the outer ring of the Visualiser, its most likely the Visualiser operative controls work on many levels and that the doctor only placed them as main dials as a tribute to his human companions.

The voyeuristic aspect of the Time Lords is kind of implied by their having a Panopticon with a big Eye at its centre, too. It's their viewing gallery to keep an eye on all creation, isn't it?

I love that there can be a half-hour documentary about a prop from 50 years ago that's basically a TV with a fancy frame around it.

Amazing to see your return! I was literally rewatching your Cushing movie videos yesterday! I hope this is the start of a new run of your one of a kind content.

Excellent. Glad to see you back on great form. Especially with the detailed explanation about the difficulties of visualising the past. No wonder the Doctor in early years could barely steer the TARDIS if you use the same premise. Banana.

Great to see you guys back with a new episode, detailing the finer points of the Dalek episodes. Well done.

The time space visualiser was a gift from the Xerons (Jeremy Bulloch and co) from the previous adventure, The Space Museum.

I've been watching your videos since the Remembrance of the Daleks video. Glad to see you're back!

Back with a banger. What a great video. Don't fear Big Brother is watching you, be afraid the mysterious time travelling Doctor is!!

Maybe Ian was so impressed with seeing Lincoln because he knew the odds of seeing him in person due to fact The Tardis never goes where they want it to go.

The Time and Space Visualiser was given to the Doc at the end of The Space Museum, yeah he was repairing it and should have asked Vicki for help. But what's interesting is, it's never mentioned again (as far as I know, Classic Who is tricky to check, as so much is still missing), but oddly a Time Scanner was mentioned in The Moonbase leading into The Macra Terror, so maybe the TASV was incorporated into the console some how, as it wasn't seen again (as far as I know, again) in The Time Meddler. (If anyone has a 'spare' copy of the Program Guide from around 1990, I would like to see it, as I no longer have access to my own one, or the updated version either). Pictures on the scanner to temp the travellers outside also happened earlier in The Edge of Destruction and then were followed by a visual representation of the journey due to the fast return switch.

I have missed this channel. Welcome back to youtube. I had assumed in the Doctor Who universe there was extensive use of telepathic interfaces. So things like the time viewer (and TARDIS controls) were merely props to allow for people to concentrate their thoughts on but the real control was done with their minds. This allowed untrained people to control complex items based on technology beyond their understanding, such as steering the TARDIS. This also allowed for a form of AI to interpret the requests of the time viewer to get the correct vision based on what the user was thinking.

Welcome back. One about the different Dalek mutants and their design, canon status and studio production would be very, very cool.

The return of the king

"A list of 30 billion planet names to be written on the control panel, which would require a really small font" killed me. excellent delivery

I was literally eating a banana when I skipped back to read all of that! You’re amazing :)

I remember seeing a draft of this on Patreon last year, great to see it completed, great work as always

Wonderful, a real treat of DW trivia, neatly wrapped on the theme of the TSV. Great visuals. Ideal for a rewatch very soon.

First video I've seen of yours, I LOVE IT! I saw that you just came back from a hiatus, please keep making content! It's really good!

Been eagerly awaiting an upload from this channel. And you have delivered! Great job!

I was ridiculously excited to see this video had appeared. Fabulous, as always. Thank you!

Amazing as always! So glad there’s another episode! 👏🏻

Excellent video, I knew there would be a series 2. I can tell a lot of research went into this video, I do hope we can see more dalek videos.

4:23: Yeah, that is a creepy thought in more ways than one! A few years back, I read this book, _The Light of Other Days,_ written by Stephen Baxter with Arthur C. Clarke-and yeah, the inventors do get personal with it! And in response, so does civilization: if privacy is dead, why bother hide _any_ activity? But the scary part of the notion is if young Time Lords consider putting together something like this device as child’s play, and if the device works the same way as the device in the Baxter/Clarke novel via the controlled use of wormholes, then the universe is in trouble indeed!

Fantastically researched as always. Brilliant.

14:45 - so the Doctor invented “What Three Words”… (Or perhaps he should call it “What Three Worlds”). Thanks for the upload, great insights as always. 🙂

Maybe the labels as per Terry Nations original design are written in psychic ink, so you always see a button that has what you need. Also, if the scope is (possibly) reading the person’s mind, it knows exactly what they are interested in. (Shades of “the moment” because it can see your thoughts).

Literally just started re-watching your stuff today, what a coincidence and a nice surprise

Great to have you back. And with such a deep dive into this deeply weird invention to boot! Your research is very much appreciated

Yes, you’re back…

Absolutely superb and really makes you think more about the mind of the writer(s) and what they were thinking about when they wrote the initial draft of stories. Thank you and wow I can't believe it's been two years since your last video.

Just remembered this chanel yesterday, and now boom, a new video after two years

amazing - so glad to have you back!

Superb, as ever. Always loved how the prop is made of those banana shaped sections around a hole for a monitor ❤️

Very enjoyable! I spotted this in my youtube recommendations, and presumed it must be an old one. How wrong I was. Glad to see you're back (even if only for a bit...).

"If you really want to nitpick (and who doesn't?).." I resemble that remark!

I love it that there are people in the world who take Doctor Who more seriously than I do.

I love how the thumbnail changes.....

In "The Light of Other Days" by Arthur C Clarke, the implicaions of a Time Visualiser are clearly explored. I would suggest that reading this bookwould give considerable food for thought.

Amazing to see you guys again

fascinating stuff, as always, this is such an insightful series.

Great video - especially the bit about Shakespeare and Francis Banana.

It's been a long time, but the master has returned.

I was always confused about the use of "Mars", "Pluto" etc on the visualiser. Regarding the accuracy of the views of Shakespeare and Lincoln I would rationalise it by suggesting that the visualiser had a telepathic component that was able to work on what the viewer was interested in seeing.

Interesting stuff! I loved the Time Space Visualizer and it's one of those things that seems like it was in a lot of early Doctor Who episodes despite only appearing in "The Chase". The item certainly made it's impact at least and it's nice to learn about some of the behind-the-scenes stuff that went on with it :)

Another great video. I thought the visualizer prop had an interesting design that reminded me of a United Jukebox. Thanks for the fun content

A TV that allows you to see any point in time would certainly come in handy when confronting an enemy? To see what they do to defeat you and then confront them with that knowledge by going back in time would guarantee you a victory.

No wonder the Doctor’s so worried about browser history with all the snooping he’s been doing. Glad to see one of my favourite series on KZfaq back, long live the Terry Nation Army!

The return of Dalek6388? Oh wow

Fantastic video, and well done slipping in that shot of Nyssa. 😉

So glad your back !! Love this channel !

I have often thought a lot of this - glad it wasn't just me :) - I did wonder why the planets of OUR solar system were listed around the screen.... SO good to have you back... great video, as always, really interesting and rewatchable :)

My first time on your channel,fantastic stuff. Great pick up on the device and fab ideas. I like the end of Wheel in Space too but that's more of a recording and a neat way to a repeat episode,almost a fourth wall break 😃 It would take a clever writter to use this device again but we can hope. Will definitely tune in for more.

28th of April my birthday and I love these videos what a present this was!

So many good points brought up in this.

Bannana , even thought this ep was not purely on the Daleks I did enjoy this and would love to see more on the prop side from any Dalek story tbh, I loved this and the tiny blink and you miss it gags, my type of humour, also nice attention to detail on the theme, that way we can tell which series we are watching hopefully in the next 5 years when binge watching it all , it was almost like a remix, looking forward to more Cameron

Always look forward to one of these

"Yes I'm back with you" and we are all so very grateful for it

Came back for a rewatch to spot some of the extra little details. Nice touch for the original Visualiser concept having a mix of classic and nuwho planets. Also, banana.

Wonderful to have you back. Excellent stuff as usual, if a little “banana”s

Well, that was an absolute delight - and the discussion of privacy issues related to viewing past events have me seeking out a copy of "Other Days Other Eyes" by Bob Shaw. Also, banana.

I'm glad you're back!

Love it! Welcome back!

Banana. Another excellent video, and well worth the wait! One thing: about the time space visualiser making a mockery of The Deadly Assassin, the Doctor points out in Brain of Morbius that a Time Lord could place a barrier around their mind, so perhaps it's useless on Gallifrey? I know this doesn't fully account for The Trial of a Timelord but whatever.

Excellent as always. Would love to see something from the first movie covered one day!

The irony of explaining the use on the prop of planet names from only our solar system (excluding Mercury) as the designers getting them from a textbook, using a clip from Red Dwarf with Holly reading space facts from a textbook where only one planet is actually named (Mercury) :D

Good to see you back!

Having recently listened to the Big Finish audio story ”The Fourth Wall” this video felt oddly topical to me. In said audio story the sixth doctor uses the time-space visualiser to watch a cricket match from 2006. It’s probably one of those things you just shouldn’t think too much about, but then again if it is supposed to exist and work as it does in the Chase there are unavoidably a lot of questions that could be raised.

Welcome back!

I find it fitting that the only way that event of the beetles can be viewed is through Doctor who makes it kinda true in a way the delight that Viki feels as in a way it preserves that event for future generations.

What would have been funny is if they were scanning Queen Liz 1.0 and they happened to see the TARDIS and the 10th Doctor

I never thought I would see a Doctor Who/The White Stripes crossover in a theme song, and have subscribed because of it lol. Simply amazing, and the content is outstanding as well!

LOVE IT! Welcome back, guys.

Insightful as always.
