Editing Timeslip (section)

==Archive status==
Most of ''Timeslip'' was originally recorded on colour [[videotape]]. An exception was episodes 23 and 24, which were recorded in black and white due to the so-called [[Colour Strike|colour strike]], an [[industrial action]] by technicians that affected many ITV programmes at this time.<ref>Pixley, ''Timeslip Episode Guide''.</ref> Today, only the final episode of "The Time of the Ice Box" survives in its original colour format. The remaining episodes exist as black and white [[telerecording]]s. Research for the 2009 documentary 'Timeslip: Behind the Barrier' revealed that only two episodes were recorded in black and white. An extra scene for episode 25 had to be taped during the same recording session, meaning that this episode was broadcast only in black and white.

It is believed the original videotapes for the wiped episodes were wiped and reused by [[Central Independent Television|Central]] in 1982 or '83 after they took over from ATV providing ITV programmes to the Midlands during an archive purge of programmes of their predecessors. At the time, these programmes were seen to have no commercial value and were deemed worthless.<ref>Worthington, T. ''Sapphire & Steel Viewing Notes'' Network DVD. Page 18, Paragraph 1, 2007</ref> Other sources claim that when Central had taken over, it was found that the videotapes had been badly damaged by age and poor storage conditions and were disposed of on the grounds of poor technical quality unsuitable for broadcast.<ref>Unknown.
