BBC Ceefax service closes down
BBC Ceefax, the world's first teletext service, has ceased transmission after delivering 38 years of up-to-the-minute news and sports updates to the British public.
Olympic champion Mary Peters closed the service when she turned off the last analogue TV signal in Northern Ireland at 11.30 on Tuesday night as part of the country's switch to digital broadcasts.
Former prime minister John Major said Ceefax would be "much missed".
"At moments of high pressure, with little time for detailed examination of the news, Ceefax headlines offered an instant window on the world," he said.
"From breaking global news to domestic sports news, Ceefax was speedy, accurate and indispensable. It can be proud of its record."
The Plain English Campaign honoured the service with a lifetime achievement award for its "clarity" and use of "everyday words".
Ceefax was launched on September 23, 1974 and promised BBC viewers the latest news headlines, sports scores, weather forecast and TV listings in the pre-internet era.
Its aim was to give viewers access to the information coming into the BBC newsroom.
At its peak in the 1990s, the service boasted 20 million viewers who checked the service at least once a week.
It was particularly popular with sports fans, enabling them to keep tabs on the latest score in multiple fixtures.
Olympic hero Sebastian Coe said Ceefax had been "an invaluable news service for every sports fan over the last 38 years".
"I have checked in on many a sports news story, track and field triumph, and Chelsea results."
