Rest in Peace, Ceefax

Add as a preferred source on Google

You may have missed it, but a little bit of television history came to an end this weekend as the BBC essentially pulled the plus on its Ceefax transmissions, bringing to an end the world’s first teletext service.

Officially, the service doesn’t actually end until this Wednesday, when Northern Ireland broadcasters complete the digital switchover from analog to digital transmissions, but with the BBC sending the final update to the service yesterday, it could be considered that all that remains of the service for the next couple of days is a ghost of what was, at one time, a proto-Internet that introduced multiple generations to the idea of regularly-updated written content available electronically, offering an update to the notion of newspapers as a permanent information source of unchanging record.

Ceefax – Its name a phonetic play on the idea of “see facts” – originated in the 1960s, when two BBC engineers, Geoff Larkby and Barry Pyatt, were tasked with creating a way in which the BBC could make use of its non-programming “closedown” time by transmitting what was then described as “the equivalent of one page of The Times newspaper” in terms of information. It took until the early 1970s before the project actually got anywhere, by which point both Larkby and Pyatt had left the corporation; nonetheless, their brainchild – which had by 1972 been given the name with which it became famous – was finally officially launched on September 23, 1974 after two years of testing, with the technology behind it also being used to create an early form of closed captioning for deaf and hard-of-hearing viewers.

In pre-Internet times, Ceefax – and the parallel service from the BBC’s independent competitor, Oracle – became something of a cult within the United Kingdom, a mass media that was nonetheless often ignored or forgotten by many, and therefore something able to take more creative risks in terms of writing and reporting; by the mid-1980s, it was no longer just broadcast during closedown hours, but available at the press of a button at any point during the day, and able to offer up-to-the-minute news coverage of breaking stories in a way that television and radio weren’t quite equipped to until the creation of 24-hour-news channels. As the Ceefax system became better known, it became the basis for all Teletext broadcasting in Europe, eventually becoming recognized as the World System Teletext.

Of course, as technology improved elsewhere, Ceefax (and Teletext in general) started to seem outdated and somewhat irrelevant when compared with both the Internet and text-based services available through digital sources. Britain’s independent networks dropped Oracle broadcasts back in 2009, and Ceefax has been facing a slow, drawn-out end since plans for the UK’s television to go all-digital were announced in 2006. Come Wednesday, Ceefax will become just a footnote in technical history, but speaking as one who feels as if he was taught to read the Internet by Ceefax, it’ll be one that’ll be much missed.

Google has been finding more ways to make Gemini a part of your daily routine, from putting together playlists to ordering groceries through your favorite apps. Now it's expanding those capabilities to more services, with Google Search joining in, too.

The company has announced a new Connected Apps Platform that makes it easier for developers to bring their services to both Gemini and Search. Alongside this, Google is adding new partners to its growing lineup, bringing more of the apps people already use into its AI ecosystem.

AI bots are now trying to sabotage public health policies, like banning disposable vapes
Thousands of AI bots voted in a public health poll to block sales restriction on disposable vapes. It's like Big Tobacco is back from the dead.

In the broad context of AI and its perceived harms, health and medical risks often pop up in the conversation. The warnings even come from frontier AI labs, such as ChatGPT-maker OpenAI and Anthropic, both of which have warned about misusing AI to cook up bioweapons. Security experts have already spotted a few such incidents in the wild, especially with the usage of AI models without any solid guardrails. 

Well, it appears that the risks run deeper. As per an analysis appearing in the British Medical Journal (BMJ), AI bots are now being deployed to influence public policies governing health risks to citizens. In this instance, an attempt was made using AI bots to thwart regulations that aim to restrict the sale of disposable vapes, all while disguising the manipulation efforts as a response from real humans.

A tiny smartphone gadget can detect some of the nastiest chemicals in your water
Scientists built a tiny smartphone gadget that can spot toxic 'forever chemicals'
Smartphone-connected drinking water safety sensor Featured

What if checking your drinking water for dangerous chemicals were as simple as plugging a tiny gadget into your smartphone? Researchers in Japan have developed a compact sensor that could make that possible, potentially bringing sophisticated water contamination testing out of expensive laboratories and into people's hands.

Scientists at the Okinawa Institute of Science and Technology (OIST) have created a portable device capable of detecting extremely low concentrations of PFAS, commonly known as "forever chemicals." The findings were published in the journal Biosensors and Bioelectronics, which demonstrate how an inexpensive sensor and a smartphone could make identifying potentially harmful chemicals in water a lot easier.
