Sixty-seven years ago today, on April 29, 1953, the first-ever experimental broadcast of a TV show in 3D happened, via KECA-TV in Los Angeles. If those call letters don’t sound familiar to any of my Southern California audience, that’s because they only lasted for about the first four-and-a-half years of the station’s existence, at which point they became the now very familiar KABC-TV, the local ABC affiliate also known as digital and broadcast channel 7.
The program itself was a show called Space Patrol, which was originally a 15-minute program that was aimed at a juvenile audience and aired daily. But once it became a hit with adults, ABC added half-hour episodes on Saturday.
Remember, at this point in television, they were at about the same place as internet programming was in 2000.
By the way, don’t confuse this show with the far more bizarre British production of 1962 with the same name. It was done with marionettes, and judging from this promotional trailer for a DVD release of restored episodes, it was incredibly weird.
Anyway, because of its subject matter and popularity, it was a natural for this broadcast experiment. This was also during the so-called “golden age” of 3D motion pictures, and since the two media were in fierce competition back in the day, it was an obvious move.
Remember — at that time, Disney didn’t own ABC, or anything else. In fact, the studios were not allowed to own theaters, or TV stations.
The original 3D broadcast was designed to use glasses, of course, although not a lot of people had them, so it would have been a blurry mess. Also note that color TV was also a rarity, so they would have been polarizing lenses rather than the red/blue possible in movies.
Since it took place during the 31st gathering of what was then called the National Association of Radio and Television Broadcasters (now just the NAB) it was exactly the same as any fancy new tech rolled out at, say, CES. Not so much meant for immediate consumption but rather to wow the organizations and companies that could afford to develop and exploit it.
Like pretty much every other modern innovation in visual arts and mass media, 3D followed the same progression through formats: still photography, motion pictures, analog video and broadcast, physical digital media, streaming digital media.
It all began with the stereoscope way back in 1838. That’s when Sir Charles Wheatstone realized that 3D happened because of binocular vision, and each eye seeing a slightly different image, which the brain would combine to create information about depth.
While there was a too-cumbersome to be practical system that projected separate images side-by-side patented in 1890, the first commercial test run with an audience came in 1915, with series of short test films using a red/green anaglyph system. That is, audience members wore glasses with one red and one green filter, and the two images, taken by two cameras spaced slightly apart and dyed in the appropriate hues, were projected on top of each other.
The filters sent each of the images to a different eye and the brain did the rest, creating the illusion of 3D, and this is how the system has worked ever since.
The first actual theatrical release in 3D premiered in Los Angeles on September 27, 1922. It was a film called The Power of Love, and it screened at the Ambassador Hotel Theater, the first of only two public showings.
You might think that 3D TV took a lot longer to develop, since TV had only been invented around this time in 1926, but, surprisingly, that’s not true. John Logie Baird first demonstrated a working 3D TV set in 1928. Granted, it was an entirely mechanical system and not very high-res, but it still worked.
Note the timing, too. TV was invented in the 1920s, but didn’t really take off with consumers until the 1950s. The world wide web was created in the 1960s, but didn’t really take off with consumers until the 1990s. You want to get rich? Invest in whatever the big but unwieldly and expensive tech of the 1990s was. (Hint, related to this topic: 3D printing.)
That 30 year repeat happens in film, too. As previously noted, the first 3D film premiered in the 1920s, but the golden age came in the 1950s. Guess when 3D came back again? If you said the 1980s, you win a prize. And, obviously, we’ve been in another return to 3D since the ‘10s. You do the math.
Oh, by the way… that 30 year thing applies to 3D printing one more generation back as well. Computer aided design (CAD), conceived in the very late 1950s, became a thing in the 1960s. It was the direct precursor to the concept of 3D printing because, well, once you’ve digitized the plans for something, you can then put that info back out in vector form and, as long as you’ve got a print-head that can move in X-Y-Z coordinates and a way to not have layers fall apart before the structure is built… ta-da!
Or, in other words, this is why developing these things takes thirty years.
Still, the tech is one step short of Star Trek replicators and true nerdvana. And I am so glad that I’m not the one who coined that term just now. But, dammit… now I want to go to Tennessee on a pilgrimage, except that I don’t think it’s going to be safe to go there for another, oh, ten years or so. Well, there’s always Jersey. Or not. Is Jersey ever safe?
I kid. I’ve been there. Parts of it are quite beautiful. Parts of it are… on a shitty reality show. Pass.
But… I’d like to add that 3D entertainment is actually far, far older than any of you can possibly imagine. It doesn’t just go back a couple of centuries. It goes back thousands of years. It also didn’t require any fancy technology to work. All it needed was an audience with a majority of members with two eyes.
That, plus performers acting out scenes or telling stories for that audience. And that’s it. There’s you’re 3D show right there.
Or, as I like to remind people about the oldest and greatest art form: Theatre Is the original 3D.
Well, nowadays, the original virtual reality as well, but guess what? VR came 30 years after the 80s wave of 3D film as well, and 60 years after the 50s. Funny how that works, isn’t it? It’s almost like we’re totally unaware that our grandparents invented the stuff that our parents perfected but which we’re too cool to think that any of them are any good at.
So… maybe let’s look at 3D in another way or two. Don’t think of it as three dimensions. Think of it as two times three decades — how long it took the thing to go from idea to something you take for granted. Or, on a generational level, think of it roughly as three deep: me, my parents, and my grandparents.
Talk about adding depth to a viewpoint.
