ANYONE WHO GREW UP in the seventies will have fond memories of Teletext, the television-based textual information and entertainment service that many see as a forerunner of the Internet and the world wide web.
Originally developed by the BBC to deliver closed captioning to television audiences, Teletext became the point of last resort for the chronic insomniacs, sports nuts and information addicts throughout the UK.
At one time the news service alone had a staff nine which would constantly roll out 30 pages of constantly updated news, and for many a small boy it was their first contact within anything close to computing.
You can barely imagine the excitement created by calling up at will literally dozens of pages of blocky text and badly drawn sprite graphics, and each page only took three or four minutes to draw. It truly was a sight to behold.
The service was tested in the early seventies on an audience of three or four people who had a suitably equipped TV - keep in mind that, at this time, most sets didn't even have a remote control - but by 1982, more than 2 million compatible sets had been sold and a virtual panoply of information was available to anyone with the patience to sit through 29 pages of irrelevance to get to page 30, which was the one you actually wanted to see.
On its launch, the Times said: "Unseen by all but a few of Britain's millions of television viewers special signals of great importance are quietly being carried 'on the back' of Top of the Pops, Tomorrow's World and other regular BBC1 programmes. When unscrambled these signals produce silent 'pages' of information which are displayed on the television screen at the press of a button".
Teletext was, despite its retrospective shortcomings, a technological triumph given the resources available. Each page contained just one kilobyte of data and that data could only be transferred during the field blanking interval, where the rasterization line moves from bottom of the screen back up to the top.
Teletext even introduced a whole generation of kids who couldn't afford a computer to on-screen gaming. With just four channels on offer, many a rainy school holiday was spent transfixed to the flickering screen playing the likes of Bamboozle, which was basically Who Wants to be a Millionaire without the fancy set, Chris Tarrant's smug, grinning face, and the chance of winning anything at all let alone a million quid. The game used the Fast Text keys, the same four coloured buttons which remain on just about every TV remote until this day, to select your answer to a multiple choice question.
The fact that the questions were updated regularly, sometimes even daily, was a source of great excitement in playgrounds throughout the UK, and completing the quiz in one go each time it was updated was a great source of bragging rights for spotty adolescents everywhere.
Those of you who worked out how to cheat the quiz - there were a number of closely guarded secrets to hacking the system - should be ashamed of yourselves. Mind you, most of you are probably raking in the cash working for Internet security companies or the Russian Mafia by now.
Game Central - found on page 806 if our beer-addled memories serve us correctly - was essential reading for Sinclair Spectrum and C64-owning game junkies. Four whole pages of gaming news, updated daily, at a time when numb-thumbed juveniles were starved of information about their second-favourite hobby.
But it wasn't all fun and games. Teletext has been used as a reliable news source for decades, and some of us can remember turning back to the old workhorse on a number of occasions, the most memorable of which was on September 11th 2001 when the terrorist attacks in the USA caused most of the major Internet news portals to collapse under the weight of user demand. Because Teletext is a broadcast service, never ground to a halt, no matter how many people were using it.
And in the days before 24 hour digital news channels, sales of teletext-capable TV sets were dramatically boosted by international events like the Falklands war which saw hordes of news-hungry punters rushing to Rumbelows to update their ancient equipment.
Supported by on-screen advertising, in its heyday Teletext posted profits of up to £30 million and was an essential service for anyone wanting to book a holiday, check the local news, keep up to date with regional weather and traffic reports or just waste a few hours when the daytime TV schedules were clogged up with Crown Court and beardy boffins from the Open University droning on about quadratic equations.
Sadly, Teletext is no more. Killed off by its bastard progeny the Internet, with its unending output of pornography, misinformation and glossy marketing cobblers. It's true that some of the more commercially successful chunks of the service will survive in one form or another on the red button of your flat screen TV's remote, but today is a sad day indeed.
Teletext was a peculiarly British institution of which many of us have very fond memories and we mourn its demise. µ
The "Teletext" that this article refers to is the commercial analogue and digital info service that appeared on ITV, Channel 4 and Channel 5 if I remember correctly.
I was hugely disappointed with the digital version of commercial teletext - it was no faster than analogue teletext (and, in fact, modern teletext sets could cache analogue pages and sub-pages, meaning that digital teletext was often slower since there was no cacheing) and with the advent of media centre PCs and broadband, you were better off switching to a Web browser on an attached PC for info.
One thing that always surprised me about digital teletext on both the BBC and commercial channels is their distinct lack of still photos (except in bleeding ads on commercial text!) - I *never* saw an article (news, sport, entertainment) with an in-story photo in it, despite the digital text standard supporting this. Perhaps it too is bandwidth limited and this would slow down the page cycling?
One recent thing I'm lamenting more than the passing of commercial teletext is the dropping of channel 301 on Freeview. This basically cut the red button additional video streams (usually used for sporting events) in half and has actually meant that some of the video streams have ended up on the Net only and not available via the red button (a recent example was a midweek Final Score on the Net only vs. some showjumping on the red button). I used a PC attached to my TV to get a full screen Flash player feed, but it wasn't particularly clear. All this to make way for HD Freeview that no-one has equipment to decode yet!
I use it heavily for checking scheduled programs and fast news updates during commercials.
And quite popular...
I bought a couple of Philips Teletext decoder boards from a surplus store in Worthing (GWM Radio - anyone!?) with a view to hooking them up to my Commodore 64 so I could call up pages from the computer - sometime in the late 80s this was!! Never got round to it.
I still have them somewhere, but I suppose there's no point now. Mind you, I don't have the C64 anymore!
Mumble mumble. Get off my lawn etc.
News, sport, weather, world time, world weather, flight arrivals and departures from all the country’s international airports, closed captions, stock market info, interest rates, Lotto, even the 2008 election results (still available)! Though I don’t think I’ve come across any page with as many as 30 subpages here.
But it’s all only on analog. There’s a “TTX” button on my Freeview remote, but it never brings up anything more than a black square with the number “100” at the top left.
...the software distribution system they built into it?
The BBC Micro teletext adapter could download programs that were beamed over the airwaves.
Yes it took ages, but in the 1980s when access to a wide area network usually involved a 300/300 modem (and getting shouted at by your parents for hogging the line for 2 hours), it registered pretty high on the geek scale.
I am amazed you made it through an entire article without blaming Apple for the World Wide Web. It was invented on a NExT Cube, made by that same Steve Jobs you drag through the mud daily. Either you have come to your senses or your lynch mob of writers is slipping.
To bad modems couldn't keep up with speed, I'm sure they could with some innovative tech. We use to share programs and such. Can you imagine getting out of the grasp of the MPAA/RIAA by setting up BBS'S again. I kind of wish some high tech people would look into it or am I just dreaming. No central ISP doing a DPI and Throttling.
Tim Berners Lee famously invented the www around 1994 because hierarchical alternatives like Gopher cost money. Now if the web as we know it hadn't happened, and an indexed system like Gopher had become dominant, then Teletext would indeed be have been a precursor to how we relate to data today.
Bob, teletext didn't have music. You are confusing it with the full screen broadcast of selected pages that the BBC used to foist on people when they didn't have shows to fill the time slots.
On demand text, due to the tiny, tiny amount of bandwidth available, couldn't do anything but blocky text.
Of course you might well have just forgotten to press mute...
This is terrible. Where else are we ever going to find the same kind of music that you get on teletext?
Nothing else in the world is like it. Not lifts, switchboards, Guantanamo Bay, Smooth Radio overnight shows, or even weekend Radio 2.
No, we didn't have Teletext, but oh the memories of BBSes and the old computer communication systems that existed before the Internet became popular. They were and are better than all this degenerate Twitter or whatever crap that kids these days think are so important.
Can't believe you mentioned the rather cack Game Central but not its great and infamous predecessor: Digitiser.

Either Bamboozle was amazing, or WWTBAM is crap.
Or both.
