== History ==

BBC Four launched on 2 March 2002 at 19.00 [[Greenwich Mean Time|GMT]], having been delayed from the original planned 2001 launch. The channel replaced [[BBC Knowledge]], an educational and cultural channel which had undergone many changes throughout its lifetime; in its final format it carried a schedule of documentaries and art programming, essentially a test of the new BBC Four schedule. BBC Four would rebrand this channel, and bring it into line with the well recognised BBC One and Two brands at the same time. Planning for the new channel, along with the new [[BBC Three]], had been in progress since October 2000; however, the incumbent government delayed approving the new BBC digital plans. The BBC Four plans were approved earlier, and as a result launched before BBC Three.

BBC Four was different from the old BBC Knowledge: the channel would be more heavily promoted with more new and original programming and the channel would not be broadcast 24 hours a day. This was due to the fact that on the Freeview [[digital terrestrial television|digital terrestrial]] platform, BBC Four is broadcast in a [[statistical time division multiplexing|statistically multiplexed]] stream in Multiplex B that timeshares with the [[CBeebies]] channel (which is on air from 6.00 until 19.00). As a result, BBC Four broadcasts from 19.00 to around 4.00 each night, with an hour's down-time and promotions for CBeebies before the start of that channel's schedule.

On 12 May 2011, BBC Four was added to the Sky [[Electronic program guide|EPG]] in Ireland on channel 230.<ref>{{cite web|url=http://www.theairwaves.net/channelnews/4399-ireland-extra-bbc-channels-being-added-to-sky-epg|title=Ireland: Extra BBC channels being added to Sky EPG|publisher=The Airwaves|date=2 May 2011}} {{Dead link|date=September 2011}}</ref>

== Organisation ==

BBC Four forms part of the [[BBC Vision]] group, and as a result, the channel controller is answerable to the head of this executive department: Emma Swain, as of 2012. The channel direction is determined by the channel's remit, set by royal charter and the corporation's governing body (the [[BBC Trust]]), and by the channel controller. In October 2013, following the departure of Richard Klein from the controllership, the management of the channel changed, with the role of Controller of BBC Four scrapped: from this point the Controller of BBC Two would have ultimate oversight of BBC Four as part of their role, absorbing some of the former duries of the Controller of BBC Four, but a new 'Channel Editor' post, reporting up to this controller, would be created to take day-to-day charge of Four. The controllers of BBC Four to date have been:
