The ident package was launched in June 1979. The ident was aired through a solid-state computer device, not unlike the one used later for BBC1's Computer Originated World, built by BBC engineers, and designed by Oliver Elmes. The concept of the double striped '2' had been around for a long time: following the two television channels dropping corporate branding, a similar look was adopted by both channels featuring double striped numbers and BBC letters. The doubled striped '2' had been in use on programme promotions since 1977 and on holding slides since 1978.
The ident itself featured a cream, double striped numeral 2, with two orange lines either side going off screen. The whole ident had the illusion of three dimensions, with orange shadows, all on a black background. The ident would either remain static, scroll in from the left hand side or scroll out to the right. The form up ident was accompanied by an electronic fanfare, which was dropped in 1983. A subtitled programme would be accompanied by the additional caption below the numeral stating 'Ceefax 270' and later following a change of page 'Ceefax 888'.
The clock which accompanied this new look was located in the BBC Two Noddy room and comprised an orange clock face with counters of ever increasing thickness and with a 'polo' mint centre upon a black background. A plain orange and white 2D striped '2' logo was placed below the clock. The use of this old clock was due to the fact that the technology did not exist for an electronic timepiece, and would not until 1980, when an electronic timepiece was finally obtained for BBC2. This new electronic clock had no second hand judder and had a changed design, featuring two dashes at the quarter hours and single dashes elsewhere. The polo mint centre was abandoned in favour of a simple centre dot, and the 3D striped '2' logo adorned the bottom of the screen, although it was unanimated.
Promotional style wasn't uniform, but generally featured the striped '2' in the promotion in one form or another, whether at the beginning or appearing on the end slide. Programme slides featured a large white 2 with programme title overlaid the bottom of the image. This branding preceded the inception of the new ident by several months, with slides featuring the striped '2' from as early as late 1978. The BBC2 special Christmas ident of 1978, featuring rotating buglers, also incorporated this version of the striped '2'.
A variation of the look was used during the Daytime on 2 strand showing schools programmes, which featured the ident with an orange gradient background. Regional variations of BBC2 featured the region name below the 2.
The variation in 2010 is this look recreated using 3D software.
Some special versions were produced for public celebrations such as Christmas:
The ident was re-used in early 2005 for the opening continuity announcement in the second series of the period comedy Look Around You.
It was recreated in May 2010, with a new soundtrack, as part of BBC Two's "80's Season", to celebrate events and features from the decade.
It was then brought back twice in October 2012, with no soundtrack. The first occasion was only shown in Northern Ireland on 10 October at 12:20am, to mark the start of their digital switchover, hence bringing BBC Two NI's time on analogue television to a close. The second was shown nationally on 22 October at 4:35am to lead into the final edition of Pages From Ceefax. And on 7 October 2013, this (and its Christmas '79, '84 & '85 ident in NI), along with others was brought back for BBC Two's "Afternoon Classics" block.
