===Closure===

However, the real reason for the shift in programming was because the incumbent government delayed approving new BBC digital plans. BBC Three and Four were planned to have launched in 2001 but because of the plans being delayed, instead the BBC decided to relaunch the two channels in the meantime with the new programming. It had been planned since October 2000 that Knowledge would be replaced with BBC Four. Eventually the new digital plans were approved, in February 2002 the hours were cut back for [[CBeebies]] to launch the new channel. BBC Knowledge was closed down in the final hours of 2 March 2002, and BBC Four replaced it the next day.

BBC Knowledge from mid-2001 was essentially a test platform for the style of the new channel.
