United Plankton Pictures, Inc.

Background

United Plankton Pictures, Inc. is a former vanity card of Stephen Hillenburg, the creator of SpongeBob SquarePants. Its name comes from Sheldon J. Plankton, one of the characters from said series. In 1998, Hillenburg formed United Plankton Pictures Inc., a television and film production company, but never used an actual logo until the first SpongeBob episode, "Help Wanted". Hillenburg died on November 26, 2018, at the age of 57, due to a case of amyotrophic lateral sclerosis (ALS); however, the company remains active.

1st Logo (1997)

Visuals: On a sand coloured background is a picture of SpongeBob drawn in the same style as the Plankton creatures in the next logo (and similar to that of the SpongeBob drawing seen on the show's title card), over a sand colored background with blue swirls in rows covering it. On top of him are the hand-drawn words "CREATED BY" in black and underneath is "STEPHEN HILLENBURG" in the same color and font.

Trivia: The words in the logo were used as a copyright disclaimer for the company itself.

Technique: None.

Audio: The end theme of the pilot, which is entitled "SpongeBob Closing Theme", composed by Steve Belfer.

Availability: Only found on the original cut of the SpongeBob pilot, produced in 1997. This version never aired, and was only released to Nickelodeon employees on a VHS entitled "The Best of Nicktoons 1998". Copies of this original edit circulate online.

2nd Logo (May 1, 1999-)

1999-2012
2012-2015
2015-2022
2021-present

Visuals: On a moving ocean background with a reflection of light are some crudely drawn sea creatures, one of them being a less detailed drawing of Plankton from said series, holding hands. The words "United Plankton" are above, with "Pictures inc." below, both written in the series' font, before it was ultimately recreated and digitized in 2016 by Fredrick R. Brennan as the now famous font, "Some Time Later".

Trivia:

In the SpongeBob episode "Plankton's Army", Plankton's relatives visit the Chum Bucket and he enlists their help into taking over the Krusty Krab to steal the Krabby Patty formula. They return in the episode "Something Narwhal This Way Comes", helping Plankton get rid of the narwhals. They are based on the characters in this logo.
The water background used in this logo is also seen as part of the SpongeBob SquarePants theme song, namely the line, "Then drop on the deck and flop like a fish!".

Variants:

Starting in 2012 with the special "It's a SpongeBob Christmas!", and later with the episode "Extreme Spots/Squirrel Record", the logo is slightly redone for HD-produced episodes. The ocean background now has a greenish tint and there are two more creatures, in addition to them being drawn more smoothly, and starting in 2015 with the episode "Lost in Bikini Bottom/Tutor Sauce", the logo is more zoomed out and the creatures are smaller and further away from the camera.
From Nickelodeon's rebrand from 2009 until sometime in 2010, sometimes it will have a copyright notice (as recycled from the 2008-2009 Nickelodeon Productions "Lightbulb" logo cheaply added in).
Starting in 2021 with the SpongeBob SquarePants episode "Under the Small Top/Squidward's Sick Daze" along with Kamp Koral: SpongeBob's Under Years and The Patrick Star Show, a comma is placed inbetween "Pictures" and "Inc.".

Technique: Live-action footage.

Audio: The closing theme.

Audio Variants:

On split-screen credits airings of SpongeBob on Nickelodeon and Nicktoons from 2001-2014 along with MTV prints of the show, it's the sound of crashing waves and seagulls (the same sounds from the very end of the SpongeBob theme) that continues into the Nickelodeon logo until 2009.
On non-split-screen airings of the SpongeBob SquarePants episodes "Texas"/"Walking Small", cows (presumably from the episode's closing theme, which is Junior Brown performing the show's theme) are heard in the background.
On early SpongeBob video releases and The Patrick Star Show, it's silent.
On the November 2012 CBS airing of the SpongeBob SquarePants episode "It's a SpongeBob Christmas!", CBS' generic theme is heard.
On some seasons 8 and 9 episodes of SpongeBob, part of the 2009 Nickelodeon theme plays near the end before continuing into said logo.

Availability: Seen on SpongeBob SquarePants, and its two spin-offs, The Patrick Star Show and Kamp Koral: SpongeBob's Under Years (both which were produced prior to Hillenburg's death in 2018).

Strangely, when the episode "Wet Painters"/"Krusty Krab Training Video" aired in 2002, due to an editing error on Nick's part, the Klasky Csupo "Splaat" logo was shown in place of this on airings with split-screen credits.
On November 30, 2011, during an airing of the episode "Pest of the West", this was replaced with the Rainbow S.r.l logo. This was fixed in later airings.
The final episode to use the original version of the logo was "Hello Bikini Bottom!". The enhanced version was first seen at the end of the episode "It's a SpongeBob Christmas!", as well as all episodes beginning with "Extreme Spots"/"Squirrel Record".
The audio variant was last seen when MTV aired the show in February 2016; instead of using the show's original credits, it used split-screen credits that Nickelodeon used from September 2009 until June 2012. It made surprise re-appearances on a June 2018 Nickelodeon airing of the episode "The Hot Shot", a November 2018 airing of the episode "Truth or Square" and December 2022 airings of the episodes "Truth or Square" and "Atlantis SquarePantis" respectively, as Nickelodeon messed up the three episodes' credits and the split-screen credits template was used.
This logo doesn't appear on any of the SpongeBob SquarePants films, as they use an in-credit notice instead.

Legacy: With its reputation as one of the most memorable vanity cards, even outside the logo community, this card is a favorite for many SpongeBob fans worldwide.
