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 to focus on entertainment shows.

1st Logo (July 30, 1968-1969)
Logo: Essentially a still version of the 1968 logo, with "FROM" on the top left of the logo.

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

Technique: None.

Music/Sounds: The ending theme of the programme or none.

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 are the words "A THAMES TELEVISION PRODUCTION FOR CHANNEL FOUR" (an early version lacked the box).
 * The TV show Pauline's Quirkes (1976) had a variant that had a kaiju rise from the river and eat the logo.
 * The late-night mystery series Armchair Thriller (1978-81) used a variant of the logo set at night.
 * One episode of The Kenny Everett Video Show (1978-81) had the building domes in the logo replaced with women's breasts.

Variants:

 * 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).

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.

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".

 * 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 airings, instead featuring Granada's 1992 "stripe" end board.
 * This also appears on the Arena Home Entertainment VHS release of Lorna Doone and a DVD print of the Mr. Bean episode "Goodnight, Mr. Bean" as well.
