The Computer Originated World (COW) was the method of creating the BBC1 symbol that was used between 18 February 1985 and 16 February 1991. It was later used by the international, commercial television service BBC World Service Television from its launch until 26 January 1995.
The Computer Originated World replaced the previous Noddy globe symbols at 7 pm on 18 February 1985. Unusually, the new look was unveiled whilst the channel was still on the air rather than waiting for the following morning to launch it. The globe was created by the BBC graphics and BBC computer departments and work began in 1983. The need to replace the Noddy globes came about as the globes were the only mechanically produced idents around on national television, as more and more television companies started to use computer graphics, made popular by the launch of Channel 4. The COW was originally planned to launch on 1 January 1985, but Michael Grade, then controller of BBC1, delayed the launch to coincide with a larger schedule change that accompanied the launch of the soap opera EastEnders , and updated and renewed weather graphics. This launch was hoped to reinvent BBC1 following ratings slide and ever increasing competition from their commercial rivals at ITV. [1] [2]
The globe itself launched at 7 pm on 18 February, introducing one of the new flagship programmes: Wogan , a chat show hosted by Terry Wogan and featuring a variety of guests. The old Noddy globe had been used throughout the day until the 7 pm launch. [2]
The Computer Originated World itself is a semi-transparent blue globe with golden continents and gold "BBC1" legend located below the globe in a font similar to that used in the early days of the BBC. The globe revolved at a steady pace throughout, and had the effect of a spotlight added to the surface. The continents were placed in such a way that the continents appeared to float on the water. The caption had the option of displaying the legend 'Ceefax 170' and later 'Ceefax 888' in reference to the subtitles available with the programme. Regional variations also included a legend with the region name, also in gold, below the BBC1 legend. The globe was generated when needed by the computer programme located in a metal box. This box had switches on the front that could turn the BBC1 caption, regional caption and subtitles caption on and off, as these elements were added later. These generators were delivered to all 11 regions and installed before Christmas 1984. [1] [2] [3] Originally it was planned to be launched on 1 January 1985, but the launch was deferred to coincide with radical changes to the BBC1 schedule.
The look also featured an altered clock face to that used previously. This clock was once again electronic, but was changed to a black background, blue counters and gold hands to match the ident. The updated BBC1 legend also featured below the clock. The nations of Scotland, Wales and Northern Ireland, as well as BBC Midlands, did receive their own variations of the clock, however it is not believed that any other English regions received their own variations. The network BBC One clock did not have a centre dot; this was never rectified throughout the run of the clock due to an oversight, however the dot was present on regional variations. [2]
The new look also marked a change in programme slide design. These new slides featured the BBC1 legend upright and sideways in a black sidebar to the left of the screen. The remainder of the screen featured a picture of the programme and the programme name located at the bottom. However, the programme slides were still optically developed. This was changed in September 1988 when the introduction of Quantel Paintbox allowed captions to be created digitally. The design was altered slightly with the BBC1 legend made more textured, slightly smaller and moved to the bottom of the screen. The font was also changed to Optima, with text remaining in the same position. All this would now be located over the image rather than separate from it. [4]
Promotions were not uniform, but were based on a seasonal scheme before being replaced. The promotions usually didn't contain any channel branding but would occasionally feature parts of the BBC1 legend in the design. [4]
During Christmas times, the '1' and the globe was altered into a variety of guises. One was made for each year the ident was in existence, None were used by BBC Scotland, instead using their own idents.
| Title | Air dates | Description |
|---|---|---|
| Red Robin | Christmas 1985 | This ident had the new ‘BBC1’ logo in a snowy landscape with a robin sitting on it fluttering its wings, with another robin rotating around the logo. Two versions were made: one for day-time and one for night-time. This was the last mechanical ident produced for the channel. The ident was accompanied by hand animated promotional trails featuring the robins. The normal COW ident was instead used at nightly closedowns as the BBC deemed the robins to be "too jolly" to be used against the National Anthem. The robins were famously detonated by The Late, Late Breakfast Show host Noel Edmonds at the start of an episode of the show on 4 January 1986. |
| Cartoon 1 | Christmas 1986 | A cartoon smiling Christmas tree in a forest, with the ‘BBC1’ logo in front of it, and holly dancing around it. The ident was designed by a viewer following a Children's BBC competition. |
| Cartoon 2 | Christmas 1987 | A cartoon graphic reading BBC Christmas 1 made up of various Christmas motifs such as various presents, a candle, holly and ribbons. The short animation was designed to tie into the end of promotions. Promotional style featured a panning view into a child's nursery, before a bag falls, pouring out streamers and ribbons. This streamer animation would be played at the end of the promotion to link into the ident. It was designed by Bernard Newnham, and was the first computer-generated Christmas ident used by the channel. |
| A Partridge in a Pear Tree | Christmas 1988 | A partridge flies onto a pear tree and sits on a branch, with the ‘BBC1’ logo superimposed on top. Two versions were made one for day-time and one for night-time. At closedown, the partridge would fly close to the screen, and with a swoop, close the channel's broadcasting until the morning. |
| Spinning Top | Christmas 1989 | The globe is a spinning top, spinning at the bottom of a Christmas tree with a ribbon around with the ‘BBC1’ logo on it. Again linked in with end promotions, which would link in by means of a toy train passing in front of the screen. |
| Pop-up Book | Christmas 1990 | The globe appears superimposed on a face on the cover of a pop-up book about magic. The introduction sequence and promotions all featured the book opening and a wizard dancing round casting magic upon a variety of objects, often with a time feel, such as a large clock face and hour glass. This was the last Christmas ident not to have corporate branding. |
| Title | Air dates | Description |
|---|---|---|
| Gift Box | Christmas 1985 (Scotland) | This ident was like the regular COW globe ident, but the COW was replaced with a revolving blue Gift Box, with the continents in gold with gold wrapping paper and ribbons around it. |
| Stars | Christmas 1986 (Scotland) | Simply the regular COW globe ident, with stars covering the black background, making it like a night sky. |
| Church | Christmas 1986 (Wales) | The COW globe was replaced with a snowy church. A wreath in a circle shows where the COW would be. 3 versions were made, Daytime, Nighttime and a completely dark version. The clock was also imposed onto the footage at closedown. |
| Christmas Cake | Christmas 1987 (Northern Ireland) | A rotating Christmas cake featuring a snowy scene including a house and trees. The circular sides has BBC1 Northern Ireland written on it on both sides. |
| Animated Tree | Christmas 1987 (Scotland) | A tree is seen, the text "CHRISTMAS ON" and "BBC1 SCOTLAND" are circular around the tree, then the rest of the blue background turns into different rectangular colours. |
| Church Window | Christmas 1987 (Wales) | The COW globe is replaced with a church window, featuring a large light-decorated tree in a snowy scene as snow falls outside. A caption on the bottom of the windows reads ether "Christmas Eve", "Christmas Day" or "Boxing Day". |
| Snowglobe | Christmas 1988 (Wales) | The COW is replaced with a Snowglobe, with a tree and a snowman reading a newspaper. |
| Music Box | Christmas 1988 (Scotland) | A box opens up with a spinning tree and BBC1 on it. Scotland is seen on the front of the box. |
| Rotating Christmas Tree | Christmas 1989 (Scotland) | A tree is seen rotating, BBC1 Scotland appears on the bottom in gold text, and the star on the top shines. 2 variants were made, one animated one, and the other being a still caption of the tree covered in snow. |
| Giant Spinning Top | Christmas 1989 (Wales) | A rotating spinning top rotates as pictures of Rudolphs, Santas, and Penguins appear on it. Then the BBC1 Wales Cymru logo appears on the bottom. BBC2 used the same ident, but with a daytime background and a different logo. |
The COW was generated by a black box containing several circuit boards. Each board carried one layer of the animation - the BBC1 logo, blue background etc., with switches to input various captions when needed. Their output had an aspect ratio of 5:4 and was cropped for transmission to 4:3. It first appeared at 7 p.m. on Monday 18 February. The digital standard used is that specified by the EBU for a digital parallel interface. While the device has only analogue outputs, to suit present installations, the EBU specification defines the required sampling rates and levels for luminance and chrominance. A further advantage is that the Quantel Paintbox handles data in a form quite close, but not identical, to this format.
To produce the overall effect two full frame-stores are used. One is the foreground store which holds the highlighted gold shell, and the other is the background store for the shaded blue disc and the captions. These stores hold only a single frame, and there is no restriction on their content. They are full colour and can display any picture produced by the Quantel Paintbox. These stores are generally known as the 'fixed' memory.
The memory structure is similar to that used for the recently introduced digital Test Card F generator, but each card can hold more data, and can be a part of a larger data-base. The EPROMs used are 27128 16 kbyte devices, although the memory card can take 27256 and even 27512 devices as, and when, they become available. When fully populated with 27128s each card holds 0.5 Mbytes. The EPROMs in question contain 20 000 pixels of map data pre-rendered as frames of animation. Each card has on its side a yellow LED that lights up when that card is in use. [6]
The controller unit has a 24-bit sequence address bus giving access to 16 Mbytes, but the equipment has space for only 7.5 Mbytes, and is fitted for 5 Mbytes. The controller also addresses the fixed memory through a 19-bit address bus. This memory uses identical cards to the sequence memory and four are in parallel. A result of this is that the customising for each region affects only the data on two cards in the system. In fact, since only the caption is different for each, only 16 EPROMs are specialised.
The controller also decodes the sequence data from its highly compressed format into a usable 13.5 MHz data stream, and distributes timing information to the rest of the system. Timing control is useful, since it can eliminate the need for external synchronising. This equipment's output can be varied from over 6µs early to over 3µs late relative to the mixed syncs input reference. Digital multipliers are used to key the map onto the foreground and background data streams. These are full 8 x 8 bit devices, and correct scaling is incorporated to ensure unity gain where necessary. The two keys are processed to prevent any excess amplitude after combining.
The two data streams are added digitally, before being blanked. Normally digital blanking needs to be shaped to conform to PAL system I, but since all the signals are generated internally, correct shaping is naturally included within the data. (In any case the start and end of all lines are black.)
A new, triple-video, analogue-to- digital converter has been designed to provide the YUV outputs and an analogue matrix used for two sets of RGB outputs. Both these units employ close tolerance components to minimise drift, and hence regular alignment. A test waveform is included within the system for checking output levels and matrix accuracy.
The system also includes a large power supplier, based on a commercial unit, and a BBC designed clock generator which is common with other digital equipments.
The main store of the system is known as the 'sequence' memory. This holds the data for the map of the world for each of the 600 fields that are displayed. This data is compressed by a coding system which combines the benefits of traditional run-length coding, with the advantages of pixel definitions. There is physical space for up to 7.5 Mbytes of memory, although the addressing can access up to 16 Mbytes. For this application a field of data is stored in less than 8 kbytes of memory space, as opposed to over 400 kbytes for a full field store.
To the right of these cards are five unused slots and to the right of those is a card with a red handle, which is the processor card. The player can be made to display variants of images by changing some switch settings on the processor card.
The starting point for the sequence data was a purchased data-base of a Mercator's projection map of the world. This was edited by Computer Graphics to remove all political boundaries, and transferred from their VAX-11 computer into the Quantel Paintbox. This was used for a 2:1 size reduction which incorporated the anti-aliasing algorithms. The data was then transferred back to the VAX for encoding into the Designs Department data compression format.
The two sets of fixed data, the gold shell for the foreground and the blue disc with caption for the background, were 'drawn' on the Paintbox. This data is properly anti-aliased at source and was also transferred to their VAX-11. Further processing ensures that no degradation occurs.
Both the fixed and sequence data was transferred from Computer Graphics to Design Department on magnetic tape, using the internal post. This proved to be an extremely efficient method of data interchange, far exceeding the earlier methods of paper tape and floppy disks.
Upon the launch of BBC World Service Television on 11 March 1991 to replace BBC TV Europe, the channel reused the COW symbol. Technically, the globe itself remained the same with changes made only to presentational style and the caption below the globe and the whole look being brought into line with corporate branding at the time. [7] [8]
The ident itself was modified with the caption beneath showing a BBC corporate logo, with the slanted legend 'World Service Television' beneath, in the same style as used for regional variations of the BBC1 ident at the time. No clock accompanied the look, due to the various time zones used around the world, with serious or news programming being introduced by the globe. [7] [8]
Presentational style mirrored by that used on BBC1 and 2 at the time, and featured a static globe, positioned with Britain, Europe and Africa in view, with BBC logo beneath located in the top left corner of the screen. The logo was present throughout the presentation. Static captions also featured this globe symbol in the top left corner, located in a sidebar of generic lines, with programme title overlaid the image at the bottom of the screen. The station was also unusual, in the fact that it had a static, opaque permanent digital on-screen graphic (DOG) of the BBC logo in the top right corner of the screen. [7] [8]
The look appears to have been dropped on 26 January 1995.
The look on BBC World Service Television was dropped in favour of a look consisting entirely of real and simulated flags on the screen, with a single large BBC logo in centre screen. This was to emphasise the role that news played on the channel, and to associate itself more closely as a news channel, rather than BBC1. This is primarily evident, as the look was reused for that purpose upon the channel's split into BBC World, as well as the original BBC Arabic Television.
The Quantel Paintbox was a dedicated computer graphics workstation for composition of broadcast television video and graphics. Produced by the British production equipment manufacturer Quantel, its design emphasized the studio workflow efficiency required for live news production.
BBC World Service Television, often abbreviated to WSTV, was the name of two BBC international satellite television channels between 1991 and 1995. It was the BBC's first foray into worldwide television broadcasting. In Europe, it was the successor to BBC TV Europe, which it replaced on 11 March 1991. The service was also launched in Asia as a 24-hour news and information service with minor differences, a precursor to BBC World News, launched on 14 October 1991.
The BBC One Balloon idents were a series of idents used on the British TV channel BBC One from 4 October 1997 to 28 March 2002. The balloon theme replaced the computer-generated spinning globe that had been used as the main ident on the channel since 1991. It launched on the same day as a BBC-wide rebrand, and thus the new idents also carried the new BBC logo. The channel's name also changed from BBC1 to BBC One. This was the last ident set used by the channel when it fully closed down; the last proper closedown took place in the early hours of 9 November 1997. Starting the following day, BBC News 24 would broadcast on BBC One during closedown, which continues today.
Noddy was a camera system used for generating idents for the BBC One and BBC Two television channels from late 1963 to February 1985.
The history of BBC television idents begins in the early 1950s when the BBC first displayed a logo between programmes to identify its service. As new technology has become available, these devices have evolved from simple still black and white images to the sophisticated full colour short films seen today. With the arrival of digital services in the United Kingdom, and with them many more new channels, branding is perceived by broadcasters to be much more important, meaning that idents need to stand out from the competition.
The BBC Two 1991–2001 idents were broadcast from 16 February 1991 until 19 November 2001, and again from 9 July 2014 until 26 September 2018, on BBC Two in the United Kingdom. The idents, which consisted of a sans-serif '2' in Gill Sans, accompanied by the colour viridian, were created by branding agency Lambie-Nairn, who also created the Channel 4 logo.
The "Virtual Globe" was the method of creating the BBC1 symbol that was used between 16 February 1991 and 4 October 1997.
Martin John Lambie-Nairn was an English designer. He was the founder of his branding agency Lambie-Nairn and was the creative director of branding agency ML-N. He is recognised for having redefined television brand identity design, being the first to embrace computer technologies to apply branding to screen-based media.
The logo of the BBC has been a brand identity for the corporation and its work since the 1950s in a variety of designs. Until the introduction of a logo in 1958, the corporation had relied on its coat of arms for official documentation and correspondence, although this crest rarely appeared onscreen. With the increased role of television for the BBC in the 1960s, particularly after the foundation of ITV, the corporation used its logo to increase viewer familiarity and to standardise its image and content. The logo has since been redesigned a number of times, most recently in 2021 with the BBC blocks, a logo designed to work across media. From 1958, there have been six different BBC logos. The first logo of the network was used from 1958 to 1963, the second from 1963 to 1971, the third from 1971 to 1992, the fourth from 1988 to 1997, the fifth from 1997 to 2021, while the sixth and current logo was adopted in October 2021.
The BBC Two "Two" ident was the station identification used on BBC2 between 30 March 1986 and 16 February 1991. It was the last non-corporate look for the channel, and the only look until 2018 that did not feature a numeral '2' in the design.
BBC Schools, also known as BBC for Schools and Colleges or BBC Education, is the educational programming strand set up by the BBC in 1957, broadcasting a range of educational programmes for children aged 5–16. From launch until June 1983, programming was based on BBC1 during the daytime, apart from coverage of major news events which saw the programmes shifted to BBC2. In September 1983, programming was transferred permanently to BBC2 freeing BBC1 to develop its own daytime schedule. The strand, named Daytime on Two, remained on BBC Two until March 2010, later supplemented by the 'Class TV' strand on CBBC.
BBC One used a number of different idents from the time of the station launch on 2 November 1936 until the station took on the Mirror Globe Idents on 15 November 1969.
The Window on the World idents were a set of idents used by BBC Two from 18 February 2007 until 13 November 2014. They were created by Abbott Mead Vickers BBDO and produced by Red Bee Media. The idents featured a number 2 cut out of, or made out of parts of the everyday environment.
The Computer Generated 2 was an ident used by BBC2 between 16 June 1979 and 30 March 1986. It was the first computer generated television station identification in the world.
The Striped 2 was an ident used by BBC2 between 28 December 1974 and 16 June 1979. The ident featured a numeral 2 made out of horizontal lines.
The Cube 2 was an ident used by BBC Two between 2 December 1967 and 28 December 1974. It featured a stylised "2" that rotated on screen.
The launch ident was a television station identification used by BBC Two between their launch night in 1964 and the introduction of colour in 1967.
Throughout the years, Children's BBC, and later CBBC and CBeebies, have used a number of different identities. The branding of the stranded service is distinctive both in the past and at present.
BBC Four, and its predecessor BBC Knowledge, are both channels operated by the BBC as cultural and knowledge based channels. Their visual identities therefore have been a result of this aim.
The presentation and the identities of the BBC News channel in the UK alongside its international counterpart and the BBC Parliament coverage channel use specific identities that demonstrate their remit and purpose.
