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. 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. 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. 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. Christmas idents 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. Regional Idents Technical details Hardware 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.
