Folio Productions

1st Logo (23 March 1992)
Logo: On a green yellow shaded bwall background, we see the text fading in "Helvetica FOLIO Helvetica". Additional in-credit text may be seen underneath fading in alongside the logo; for instance "for CHANNEL FOUR".

Technique: The text fading in.

Music/Sounds: The ending theme of the programme.

Availability: Extinct, this was seen on the company's earliest documentaries such as P-Company. Like many other documentaries at the time, they are tough to find due to them being hardly preserved or reran.

2nd Logo (28 May 1992-1997)
Logo: On a gravel background with a curtain-like overlay over it, the transparent, beveled text "Garamond" is seen with "Times New Roman" and "Times New Roman" over and underneath it respectively. Like before, additional in-credit notices may be seen underneath the logo.

Variant: Programmes co-produced with Hart Ryan Productions has only the "FOLIO" portion of the logo inside a box with a white border.

Technique: Same as before.

Music/Sounds: The ending theme of the programme.

Availability: Extremely rare. This can be spotted on The Black Bag: Turning To Islam, the Cutting Edge documentary "Glasshouse", Postcards from the Edge, and Fight For Hearts And Minds. Arranging a trip to a BFI venue is one of the only methods of finding this logo. Though they possess nearly all the known releases from the company, visitors are obligated to view the content in person rather than over the internet.

3rd Logo (1997-2000)
Logo: Simply consists of the golden text "Times New Roman", with the "i"'s dot being a tilted square.

Variant: On Crime Beat, the logo is shown on the top right with its notice fully reading "a folio Mentorn Group Company Production" in a stacked format.

Technique: None.

Music/Sounds: None or the ending theme of the programme.

Availability: Only known to have appeared on Crime Beat, specifically 1998 episodes such as "Shops, Robbers, and Videotape".

 * The logo may appear in a split-screen format.
 * On McCartney vs. McCartney, the byline is removed and a copyright notice is added underneath.

Technique: Same as the 2001 Mentorn logo.

Availability: Rare. Can be seen on the Mean Streets documentary "Shops Robbers & Videotape" and series 1-5 of Traffic Cops.
