Editing BBC Knowledge (section)

==Visual identity==
{{main|BBC Four idents}}


The launch identity consisted of cartoon characters climbing 'ladders of learning' between clouds against an orange background. Illustrator Michael Sheehy designed the idents. A white, [[Logo of the BBC#1990s|BBC logo]] with 'Knowledge' after it in capital letters was located at the bottom of the screen. The ident image would also be present in the background of the end promotions, channel menus advertising upcoming programmes, and in video links presented by members of the public. In addition to this, a [[Digital on-screen graphic|DOG]] was used on the channel, located in the top left of the screen, which displayed the web address for the channel, linking in with the interactive learning element, however this was replaced with the BBC Knowledge logo before too long.

Later on, the idents changed to follow a strand layout, with different idents for each strand. These featured an object, before a fact about it related to the strand appears and ends on an image with the strand name shown clearly on screen, with a letter encircled at the centre of the screen. It is unclear whether these idents were replacements of the animated idents, or complementary to them, however it appears they complemented them, with these idents being used in the stranded sections, with the animated idents used for general interest programming.

Following the relaunch in 2001, all different idents were dropped in favour of a single ident, featuring numerous circles made out of different structures reflecting the new strands.
