NPO 1

Background
NPO 1 (formerly Nederland 1) is the first national television station in the Netherlands, which launched on October 2, 1951. It provides public broadcasting and currently exists next to its sister channels NPO 2 and NPO 3. A wide range of broadcasting organisations of the Publieke Omroep deliver programs to the channel. Since 2008, the channel is the most viewed in the Netherlands.

1st Logo (1950's)
Logo: TBA

FX/SFX: TBA

Music/Sounds: TBA

Availability: Extinct.

2nd Logo (1973-1984)
Logo: On a blue background we see a segmented purplish 3D "1", with the text "Nederland" in Helvetica above it.

Variant: There is a version where "NEDERLAND" in is the Microgramma font.

FX/SFX: None.

Music/Sounds: TBA

Availability: Extinct.

3rd Logo (1988-1991)
Logo: On a black background, two doors open up to reveal a bright light. We zoom out through a rectangle window with "NEDERLAND" in Gill Sans at the top. The doors stop and are left partially open. The window then sets in place, forming a Roman numeral 1.

Variants:
 * There is a closedown variant where the doors shut and the logo fades to black.
 * Others zoom in to the VARA logo, the NCRV logo or the EO logo.
 * There are multicolored versions with the VARA logo, the KRO logo, the NCRV logo and the EO logo under the numeral.

FX/SFX: The doors opening.

Music/Sounds: A synth and drum tune.

Music/Sounds Variant: For the closedown version, a more somber version of the music is heard.

Availability: Extinct.

4th Logo (1991-1992)
Nicknames: "Dutch Rhombus I"

Logo: In a building with pillars, open windows and doors, and a checkered floor, we see several tiles of the floor float and turn into a blue diamond, then a yellow number "1", and then back to a tile, and the process keeps repeating. The tiles are in an infinite loop, and the logo forms briefly every time the yellow "1" is in front of the blue diamond. The then-new Nederland 1 logo of the time is at the bottom-right corner.

FX/SFX: The CGI animation looping, kinda reminiscent of a GIF. Designed by Lambie-Nairn.

Music/Sounds: A jazz tune with the same four notes repeating in the background.

Availability: Extinct.

5th Logo (1992-1996)
Nicknames: "Pattern Rhombus", "Dutch Rhombus II", "Fog Rhombus"

Logo: We see a wide rhombus displaying various patterns/images while zooming out. It's seen with the top facing the camera. Once the rhombus stops zooming out, a light appears illuminating it, and we see coins in the left side of the screen when that happens. Then a blue rhombus (not very wide like the previous one) fades in and the yellow "1" appears on the center of it.

Variants: Depending on the program genre, the background and patterns that show in the rhombus change:
 * Entertainment: Dark striped pattern background, the rhombus shows other striped patterns with different colors.
 * News: Black background, the rhombus shows a weird pattern (that may be a stone pattern or the world map at night). There's also fog in this variant, which later intensifies at the second half of the logo. At the end, the logo fades out in a white color.
 * Current Affairs/Information: Static-like background, the rhombus shows the word "Informatie" in various fonts and colors. Fog is also shown at the 2nd half part of the logo, but it clears out near the end.
 * There's also a ident which shows a black background and fog, with the rhombus displaying various colorful patterns. The fog also intensifies at the 2nd half of it.

FX/SFX: Pretty nice animation.

Music/Sounds: Depends on the variant shown.

Availability: Extinct. If you live in the Netherlands, check those old recorded tapes!

6th Logo (1996-2000)
Nicknames: "Dutch Rhombus III"

Logo: Depends on the variant.

FX/SFX: A combination of live action and CGI.

Music/Sounds: Depends on the variant, but ends with a six-note tune.

Availability: Extinct.

7th Logo (2000-2003)
Nicknames: "Heart of Holland", "Head and Heart", "Dutch Rhombus IV"

Logo: We see a shot of somewhere in the Nederlands, with a large red structure in front of the screen. The structure has a large diamond-shaped hole in the center of the screen and is resting on a large trapezoid shape, and it rotates slowly around to the left as the panorama shot behind it moves faster. Suddenly, everything becomes a blur and brighten up to white as the sculpture is reversed to the other side, revealing a red diamond shape with a off-center "Arial|1" inside it in white, and everything around the diamond starts to fade to a white background. As the sculpture disappears, the edges around it sink into the background and the diamond shines, with the Publieke Omroep (a blue square and red circle paired with each other) appears in the top right corner of the logo.

Variants:
 * At closedown, the logo animation plays in reverse before blurring and stretching out of view, leaving a blank screen. If you look closely, you'll be able to see portions of the "nighttime" version of the logo.
 * Sometimes, the end result includes a translucent version one of the "sculpture" idents.
 * Most of the time, the sculpture (which is a large red square shape tilted at a 45 degree angle, resting on a large wedge and having that diamond-shaped hole at the bottom of it) is seen in various parts all around the Netherlands. Sometimes, its in full-view, while other times its barely visible around the edges. People can be seen through, around, and even in the sculpture as well.

FX/SFX: Live action and computer animation for the main idents. This was designed by BBC Broadcast (nowadays called Red Bee Media).

Music/Sounds: A calm piano tune that repeats twice in different tones, before leading to a dramatic 4-note fanfare at the end. This is rearranged and shortened usually for the "sculpture" variants.

Availability: Extinct.

Nicknames: "Dutch Rhombus VI", "Floating Nederland 1"

Logo: We see tons of Nederland 1 logos floating in the air around places in the Netherlands.

FX/SFX: Same as the 8th logo, with CGI elements.

Music/Sounds: A guitar theme with random marimba notes.

Availability: Extinct.
