SpongeBob Squarepants is the longest running Nicktoon in history, with 205 episodes created thus far. The show debuted in 1999, but only fourteen episodes actually debuted that year.
Due to its popularity, the show has been subject to both criticism and parody. It is seen by fans of 80s/90s Nick as marking a change in Nickelodeon's style.
The show was known for combining live action and animation in unique ways. The show mainly took place in the town of Bikini Bottoms.
- SpongeBob SquarePants- a cheery sea sponge (who actually looks like a common sink sponge) who will gladly work anywhere for peanuts. He works at the Krusty Krab fast food hamburger restaurant as their fry cook (although he grills all the Krabby Patties he prepares). In the first episode, he manages to help the Krusty Krab deal with being overrun with anchovies. He lives in a pineapple house. His parents resemble actual sea sponges.
- Squidward Tentacle- SpongeBob's glum, easily annoyed, octopus neighbor who also works at the Krusty Krab as the cashier (although he hates working there). He lives in a house made out of a Moai statue. He loves playing his clarinet, although he isn't very good at it.
- Patrick Star- a pink, dimwitted sea star who is SpongeBob's best friend. He lives under a rock (partially a reference to the phrase "Have you been living under a rock?", implying that the person is stupidly clueless).
- Mr. Krabs- owner of the Krusty Krab, Mr. Krabs' main obsession is money. He has a stereotypical pirate accent and resembles a pirate to some extent.
- Sandy Cheeks- a squirrel living in an underwater vivarium who wears a sea outfit when not at home. She is from Texas. She is never seen using air tanks, despite being a land mammal.
- Plankton- a one eyed plankton bent on ruling the world. He works at the Chum Bucket (made from a literal bucket), the Krusty Krab's only competition.
- The narrator- a man with a stereotypical French accent.
- Pearl Krabs- Mr. Krabs' daughter, although she is a whale rather than a crab. Despite her being a mammal, she never needs to surface.
Countless SpongeBob video games have been released to many video game consoles over the years, including a racing game.
It has been revealed that sexual references can be found in several episodes.

- The intro makes several allusions to classic TV shows.
- The portrait saying "Are you ready, kids?" and the kids responding "Aye aye, captain!" alludes to such shows as Howdy Doody.
- The portrait also has a real mouth superimposed on its animated face, using a technique introduced in Clutch Cargo.
- In one episode, a few of the characters are on a fishing trip attempting to catch "Moby Dollar" (an allusion to the classic literary novel Moby Dick). When the dollar in question appears, dramatic music similar to the Jaws theme plays.
- One character is a ghost named The Flying Dutchman, which is actually a ghost ship.
- The character Mermaid Man is mostly a parody of Aquaman of the DC universe. However, he is partially a parody of the 1960s Batman.
- Adam West, who played Batman in the original TV series, voiced the young version of Mermaid Man.
- Barnacle Boy is supposed to be a parody of Aqualad, but is partially a parody of the 1960s Robin.
- Burt Ward, who played Robin in the original Batman series, voiced a young Barnacle Boy.
- Despite the characters living underwater, gravity is not affected. All actions requiring air are also possible (except for Sandy Cheeks requiring a diving suit to survive).
- David Glen Eisley performed "Sweet Victory" in the episode Band Geeks.
- During that segment, Raiders fans can be seen crying in the audience.
- One customer orders a "Diet Dr. Kelp", a reference to Diet Dr. Pepper.
- One episode implies that "karate" is sometimes pronounced "ker-rah-TAY". This is incorrect. The traditional Japanese pronunciation is "kuh-RAW-tay" and the common English pronunciation is "ker-RAW-tee".
At least two films have been released since the show's debut.
