TV1 (Finland)

Background
In the 1970s, TV-ohjelma 1 rebranded to TV1 after the channel started broadcasting in colour. It was then rebranded to Yle TV1 somewhere around the late 1990s.

1st Logo (December 24, 1965-December 31, 1991)
Logo: On a blue background with a bright light at the center, four stylized swans, colored dark blueand white, are "flying" towards each other from all four corners, as they stop at one place in the center of the screen, creating a diamond-like shape. The word "YLEISRADIO" then appears in the middle gaps with "TV1" appearing on the lower gap.

Variant: The Swedish variant features the word "RUNDRADION" on the center of the screen. The text "TV1" is also centered.

Technique: The swans sliding in. Pretty primitive and simplistic animation.

Music/Sounds: A small-scaled, yet loud orchestral fanfare, ending with an rendition of the YLE analog notes.

Availability: Extinct on TV. Beginning on Christmas Eve 1965, this was used as a startup and closedown ident through its long run, but it could also be spotted before and after the MTV programming block. The Swedish variant was featured when the day's broadcasting begins or ends with a Swedish program.

2nd Logo (1972-1987)
Logo: A logo, in the form of a wide "1" with a transparent background and "tv" placed in the middle of it, is placed on a random spot in one of many photos.

 * An anniversary variant seen in 1986 has a black background with bright, yellow letters moving from different directions to the center to form "yle6o" with the font color changing to white. The black background also transitions into a one with a embossed "yle6o" on it. The text then emits a short, bright flash, leaving a stable bright aura around it. The channel logo then appears on the top left corner.

Technique: None for the regular variants. The anniversary variant has primitively animated letters with bright flashing.

Music/Sounds: The last eight notes of the tune used in the previous startup/closedown ident played slowly with a glockenspiel. This was redone on a synthesizer for the anniversary variant.

Availability: Extinct on TV. Each variant could be spotted prior and after the MTV programming block. There could be more of these to be discovered.

3rd Logo (August 31, 1987-December 31, 1992)
Logo: On a black background, six thin transparent plates with different sizes and gradient colors (yellow-, hot pink-, light-dark blue,, light violet and indigo) gather together from multiple directions, as the camera zooms out and rotates from the side of the structure. As we get a better view, the thin plates connect together with bright flashing seen between each one, forming a large outline of a "1" as a dark blue glow appears on the bottom part of the background. The camera then zooms in, while also rotating to another side of the number, as the thin plates start disconnecting with brief flashing seen again between them, and move away from the same direction where they came from, leaving the black background.

Variants:
 * The known prototype variant of the channel ident features a fully black background and the corners of the plates shining brighter than in the main variant.
 * Circa 1987, the promotional transition variant has the plates gathering together to form the channel logo on a fully black background. The logo then moves to the top right corner and the promo of the program fades in with the logo being visible on the corner.
 * Since January 14, 1990, the channel logo (or TV2's logo at the time but a bit shinier on the bottom) could be spotted on the intro sequence of the public broadcaster's main news program (TV-uutiset ja sää). The logo is seen on a background with shiny  stripes before the camera rotates upward and the logo is wiped away. A large ball then rises from the stripes and it starts to pulsate waves in yellow,, and . The logo, which is an "Ω" with a box around it (a bit rounder than the previous variant), then briefly fades in on the bottom before a  wave wipes it into full view. As it wipes into view, the camera zooms out and rotates as the background forms into a news clip and the text "U U T I S E T" wipes in, briefly flat before becoming 3D. The logo then settles onto the bottom center as the ball forms the circle in the logo and the lines disappear. The wave keeps moving until it fades out and the logo settles to the bottom left corner or it fades to the set and the logo flies away.
 * Between 1991-1992, the closing logo uses a black background with a miniature version of the logo placed on the bottom center of the screen and the program name (or none) and "YLE-(year)" or "YLE TV1-(year)" below it.
 * In the late 1980s and early 1990s, an additional ad bumper features both the TV1 and MTV logos on a black and dark blue background.
 * In late 1992, a simple image of the channel logo on a pale blue background was used as a transition variant between program promos.

Technique: Standard CGI of the thin plates, and the brief flashing between the connecting plates.

Music/Sounds: A series of decreasing pings repeated twice that are immediately followed by a synthesized fanfare.

Music/Sounds Variant: An alternate theme with different instruments and different ending, was featured on the promotional transition variant.

Availability: Extinct on TV. It could be spotted prior and after the MTV or FST programming block at the time. The prototype variant with a black background is known to exist and it was used since its debut in late 1987 before it was changed to main ident in early 1988. The rare ad bumper variant was used, when the public broadcaster had sponsored commercial breaks during each live airings of sport programs on TV1 channel. The simple transition image in late 1992 was most likely in temporary use before the channel's look was changed in 1993 with more active transition idents (see an example here).

4th Logo (January 1, 1992-2000)
Note: The first variant can be seen here.

Logo: For the regular ident, same as the 1st Yle logo.

Variants:
 * As the full logo is formed with "Y L E" fading in below, the "Rings" logo cross-fades to the 1987-1992 logo with a lighter tone. This startup variant could be spotted in 1992.
 * After the regular ident is completed, it fades out and a new channel logo designed by Liisa Kallio fades in on the screen. The logo has the appearance of a basic square with a stylized thick number "1" on the right side and "T V 1" written below the logo. This one was featured between 1993 and early 1998.
 * With the regular ident being completed and then fading out, another logo appears on the screen, looking like a modified version of the logo seen in the second variant. The logo is a round-edged, square with the right side having a cutout of a thick "1" like in the previous logo, while "TV1" is seen on the bottom right side of the logo. This variant could be spotted between 1998 and 1999.
 * Between 1998 and 1999, when the weekend's broadcasting begins with the children program Veturi, the ending of the startup ident features a traditionally animated fat bird falling in front of either one of the two aforementioned logo variants. We then follow the yawning bird walking on right off the startup ident, as this transitions to the opening of the children program.
 * Between 1999 and 2000, another version of the third variant was used after the children program Veturi received a new opening sequence. Before the opening, the TV1 logo gains  and white wheels and moves to the left of the screen.

Technique: Same as the 1st Yle logo.

Music/Sounds: Same as the 1st Yle logo.

Availability: Extinct on TV. Each one of the three variants could be spotted as a startup ident for the channel at that time. However between 1993 and 1998, it was possible to the second variant being spotted as a closedown ident before the teletext service comes to the screen.

Legacy: Same as the 1st Yle logo.

5th Logo (January 1, 1993-1998)
Logo: On a complex background, there is a transparent cube rotating around, with each side having a different-colored version of the TV1 logo at the time. The logo is almost invisible, with various images warping around the screen.

Trivia: The logo was also integrated into the 1993-1995 TV-uutiset ja sää title sequence as the middle cube before it faded to a plain white cube.

Variants:
 * At the start of the 1993 European Figure Skating Championships program, the logo was made without any kind of distortion, revealing that the cube has a strange moving texture on the entire translucent area of the cube, and that the edges of the cube and logos shine as well. The background shows a cloud-like wall, mostly darkened out with black and the reflections of the cube on the wall. The text "YLE" is on the bottom left side, and "TV1" in lettering is on the bottom right. The logo eventually fades out to leave the cloud background.
 * The closing logo has the logo with solid white fillings situated on the bottom of the screen, with the background being a concrete wall with a small spotlight shining on it (whose position seems to shift). Below the cube is a multicolored gradient line spanning the entire screen, as well as the program name (or none) and "YLE-(year)" or "YLE TV1-(year)" below that. Originally in 1993, the cube rotates around to a specific colored side depending on the program. There were five color variations for the cube sides used: (news and current affairs programs),  (documents), yellow (educational programs), dark orange (children's and youth programs) and violet (fiction-based programs). Since 1994, all closing logo variations ended with the  logo on the front side of the cube.

Technique: The CGI cube logo in rotation, the complex background leaving waves of colorful after images.

Music/Sounds: Part of the peaceful theme heard generally during the program schedule listing. For the variants, the start of the program for the 1st variant and either the end of the program or none for the 2nd variant.

Availability: Extinct on TV. Used as a transition ident, it is known to be seen between the program announcement and the channel's last program of the day (usually being Euronews newscast program). This transition ident is also used prior and after the FST programming block. The closing logo appeared at the end of programming at the time and may be kept on reruns.
