Missing Believed Wiped is an annual event hosted by the British Film Institute in which previously "wiped" television material from the UK, which has recently been recovered is screened.
Missing Believed Wiped was founded in 1993 by Dick Fiddy who remains involved in the event. There has also been a public effort using television spots and other media to raise awareness. Past events have featured material recovered from the personal collection of comedian Bob Monkhouse; the 2010 event featured extracts from drama recordings found at the Library of Congress in the United States.
The 2011 event on 11 December featured an early Dennis Potter play Emergency â€“ Ward 9, two rediscovered episodes of Doctor Who, and footage of David Bowie's performance of "The Jean Genie" on Top of the Pops on 4 January 1973, which was believed to have been lost. The two Doctor Who episodes were part 3 of "Galaxy 4" (Hartnell era) and part 2 of "The Underwater Menace" (Troughton era).
