Ceefax is a revamped version of Ceefax for the Raspberry Pi computer introduced in August 2016 by Peter Kwan. To view Teefax, enthusiasts connect a Raspberry Pi running appropriate software to the signal input of a Teletext-capable TV. Kwan said: “It's like the modern-day equivalent of restoring steam engines. It's completely useless but it keeps us occupied." The service has 12 pages of up-to-date news and Kwan hopes to create an online archive of old teletext pages from Britain, Germany and France. Ceefax Ceefax was the world's first teletext information service and a forerunner to the current BBC Red Button service.

Subtitle (or closed captioning) information is also transmitted in the teletext signal, typically on page 888 or 777.
