This is the first of four of the original idents, enlarged to occupy the width of today's widescreen broadcasting standard.

Probably the most well-remembered spinning blocks ident, but with a light version of the Channel 4 signature theme 'Four Score'.

An alternative version of the particles style ident, with a brasher fanfare.

Finally, an original ident, but with the new Channel 4 theme that was introduced around 1993.

American Football.

Sumo Wrestling.

Italian Football.

During the day, a select few programme menus were shown in the channel's original style. The music in the background of this one is the alternative synthesised version of 'Four Score'.

A recreation of the style of programme menu as seen from day one on Channel 4. It uses the original layout, typeface and highlighting to create a little nostalgia trip.

A very short and simple animation to promote a single programme later on in the day.

Another example of the programme menu from the 25th anniversary of Channel 4.

A final outing for the recreated menus.

Gone for the day the monochromatic shadow 3D '4' and custom typeface, and in their place the original Channel 4 logo and clean and clear Gill Sans - as perfectly shown on this trailer end-board.

Even the in-programme pointer (certainly not around twenty-five years ago) received the same attention to detail.

And finally: the end-credit promotions boards - here advertising the Channel 4 microsite dedicated to all things 'home'. Next, a promotion for the documentary 'Channel 4 at 25' already shown a few times on More4 and now to be shown on the actual channel itself. Finally, the production board complete with a fully animated Channel 4 logo.
