Thames

Background
The Thames production company was originally the production arm of Thames Television, formed from a merger of the separate previous units ABC Television Productions and Rediffusion London Productions. Even though after Thames had lost its ITV franchise in 1992 to Carlton, it continued on as a production company, which was acquired by Pearson Television in mid-1993 (itself sold to CLT-UFA in July 2000, merged to become the RTL Group, and rebranded as FremantleMedia in 2001).

In 2003, Thames was merged with another Fremantle subsidiary, Talkback to form Talkback Thames, which was then split in 2012 into four production companies, resurrecting the Thames brand.

1st Logo (July 30, 1968-1969)

Variant: On some programmes, a still version of the black background version is used.

Technique: None.

Music/Sounds: The ending theme of the programme.

Availability: Common. Many Thames shows had kept the logo, like General Franco and Special Branch, among others.

2nd Logo (November 15, 1969-September 1, 1989)
Logo: It's a still version of the 1969 logo, but with the text reading "COLOUR PRODUCTION" below the logo.

Variants:
 * Sometimes, a still version of the 1969 logo without the words "COLOUR PRODUCTION" also exists as well.
 * During the 1970 ITV strike, a black-and-white version exists, where the logo reads only as "THAMES PRODUCTION"
 * Other versions of the logo exist, reading as "FROM THAMES" or "FROM THAMES IN COLOUR", which was seen at the end of movies and imported programmes.
 * Prior to 1985, the last of these variants also included the text "© UK (year in Roman numerals)" below "PRODUCTION".
 * Another version read "Produced for THAMES TELEVISION", with "Produced for" and "Television" added above and below the Thames text which appears on Jack the Ripper (1988).
 * In 1982, Thames added a new closing logo without the reflections for its Channel Four programmes. Against a black or background was a box with a /white outline of the buildings, a /purple gradient background and the word "THAMES" inside. Underneath were the words "A THAMES TELEVISION PRODUCTION FOR CHANNEL FOUR" (an early version lacked the box).

Technique: None.

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

3rd Logo (September 4, 1989-August 31, 1990)
Logo: On a spotlight background, we see a still version of the Thames XXI logo, except the bottom triangle is wordless. Below it is text reading either "Serif" or "Serif", and the 1989 ITV logo appearing below.

Variants:
 * Sometimes, the words read as "THAMES TELEVISION PRODUCTION FOR CHANNEL FOUR", which was seen on Thames programmes for Channel 4.
 * A B&W variant of the above also exists, which was seen on a TCM airing of the 1921 film The Blot.

Technique: None.

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

Availability: Rare.
 * It appears on Thames shows such as The Bill, This Is Your Life and Harold Lloyd: The Third Genius, among many others.
 * It was also originally seen on season 3 (1989-90) episodes of Count Duckula, however it does not appear on the DVD release, nor does it not appear on VHS releases as they are often deleted out, or plastered over by either Thames Video's first logo or Cosgrove Hall Productions' second logo (which was extended on the DVD release).
 * It also appears on 1989 episodes of Never The Twain and is intact whenever Forces TV aired this.
 * Season 1 episodes of French Fields kept this intact on UK Play and whenever Alibi decides to air it.

4th Logo (September 3, 1990-1997)
Logo: Against a medium blue background is a and  version of the triangular Thames logo with the words "THAMES TELEVISION" appearing on the triangle in a Friz Quadrata font. Below that is the text "THAMES TELEVISION PRODUCTION/PROGRAMME FOR" with the 1989 ITV logo. After 1992, this became the primary logo, and the 1989 ITV logo was removed.

Byline: Beginning in mid-1996, the byline "A Pearson Television Company" was added below the triangle, and "Production" was moved on to it, now also in the same font as the rest of the logo. The copyright text "© Thames Television Limited MCMXCVI" was also added at the bottom of the screen, as it was previously on the credits. Sometimes, the Pearson byline would appear on the triangle instead of "Production" as well.

Variants:
 * For Thames' Channel Four-produced programmes, either the text "A THAMES TELEVISION PRODUCTION FOR CHANNEL FOUR" or "THAMES TELEVISION PRODUCTION FOR CHANNEL FOUR" would be displayed.
 * There was also a version with the text of "THAMES TELEVISION PRESENTATION", which appears at the end of movies and imported programmes, and in 1993 and 1996, there were also three variants for Thames' Yorkshire, Central and UK Gold-produced programmes, with the text "THAMES TELEVISION PRODUCTION FOR YORKSHIRE TELEVISION/CENTRAL/UKGOLD".
 * On programmes produced for Sky such as Great Escapes, the logo appears with the words "A THAMES TELEVISION PRODUCTION FOR SKY TELEVISION (C)(year)" appearing below.
 * In 1994, Thames' then-parent company Pearson remastered the 1973-75 documentary series The World At War, with the following plastered over the original "From THAMES" and "THAMES Colour Production" ending: following a quick montage of black and white photographs, the 1990 Thames Triangle logo (with the colour removed) appears on the screen on a black background, with the copyright date under it.
 * A variant of the above also exists where the 1990 Thames Triangle logo changes from black and white to colour, which was seen on at least one episode of the remastered version of The World At War as well.
 * Variants of this logo for Thames Video, Euston Films, and Cosgrove Hall Productions were also used.
 * There was also a version with "INTERNATIONAL" replacing "TELEVISION". The name is put on a separate bar, and the logo takes up more of the screen with no other words around it. Oddly enough, this version was seen on Avenger Penguins (the first show produced by Cosgrove Hall after Thames had lost their broadcasting license at the end of 1992). However, it was not seen on the original airing, instead featuring Granada Television's "stripe" end board.
