BBC Four

The channel direction is determined by the channel's remit, set by royal charter and the corporation's governing body (the BBC Board), 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 duties 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 from 2002 to 2016 have been:

BBC Four's primary role is to reflect a range of UK and international arts, music and culture. It should provide an ambitious range of innovative, high quality programming that is intellectually and culturally enriching, taking an expert and in-depth approach to a wide range of subjects.

On 10 September 2005, the channel began showing new idents comprising a central BBC Four logo surrounded by four quadrants which show different stages of the same footage thus making for a sort of optical illusion; for example, a swimming pool where a person on an inflatable ring appears in the bottom-left corner, though ripples don't enter the remaining quarters. Although the image appears as one at the start of the ident, by the end it is clearly four separate images.
