However, when the BBC launched The Learning Zone in 1995, it was shown during overnight downtime although latterly BBC News filled many of the late night/early morning gaps in the schedules. The last "Pages from Ceefax" broadcast on BBC1 was on 9 November 1997 but they continued to be broadcast on BBC2 until the Ceefax service was closed down. The final transmission was in the early hours of Monday 22 October 2012 and featured special continuity announcements and a specially created end caption featuring various Ceefax graphics from over the years. The music chosen for the final minutes was "BART" by Ruby, which had been frequently used for "Pages from Ceefax" and for other continuity. Since then, overnight downtime has been filled with a rolling loop of previews of forthcoming BBC Two programmes (and for a brief period in September 2016, BBC Parliament highlights ). Teefax 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.
