Paying tribute to Ceefax
BBC Ceefax, the world's first teletext service, is set for a final bow as the UK's digital switchover is completed.
Former Olympian Dame Mary Peters will turn off the analogue TV signal in Northern Ireland at 11.30pm on Tuesday.
Ceefax was launched on 23 September 1974 to give BBC viewers the chance to check the latest news headlines, sports scores, weather forecast or TV listings.
The BBC's Points of View programme looked back at Ceefax's 38 years on air.
First broadcast 21 October 2012.
