1982–1991: early years

Klasky-Csupo, Inc., got its start in 1982.^[4] It was founded in the spare bedroom of a Hollywood apartment where Arlene Klasky and Gábor Csupó were living during their marriage. 1 year later, Klasky-Csupo expanded and moved to a new location at 729 Seward Street,^[5][6][7] (Bob Clampett's studio) opening its first facility in Hollywood.

Klasky Csupo was initially distinguished by its work on logo designs, commercials, feature film trailers, TV show titles, promos and ident spots for a wide variety of clients, in the process earning a reputation as the industry's most imaginative and innovative studio. Building on its success, the studio left Seward Street to open its second facility in Hollywood in 1988 at the corner of Fountain and Highland Avenues. The studio soon grew to include six buildings that have become well known in Hollywood—in true Klasky Csupo style, the exterior walls of the buildings are decorated with large murals of its characters.

The studio's first big break came in 1987 when James L. Brooks of Gracie Films commissioned the studio to produce the title sequence for a comedy series titled The Tracey Ullman Show. In addition to the main title, Klasky Csupo was given the opportunity to produce and animate a new series of one-minute cartoons which featured a family called the Simpsons, created by Matt Groening. Klasky Csupo produced and animated all 48 shorts, and when it became one of the most popular segments on the show, Fox began airing a weekly half-hour series entitled The Simpsons. Klasky Csupo oversaw and animated every episode of the first three seasons of the series, resulting in the studio sharing the 1989–1990 and 1990–1991 Primetime Emmy Award for Outstanding Animated Program, with Gracie Films.

In addition, Klasky Csupo produced the hit video "Do the Bartman". Klasky Csupo animator and colorist "Georgie" Gyorgyi Kovacs Peluce (Kovács Györgyike)^{[8][9][10][11][12][13]} conceived the idea of The Simpsons characters having yellow skin, and Marge Simpson having blue hair, opting for something which "didn't look like anything that had come before."^[14][15][16] Klasky Csupo was also responsible for an error during the episode "Homer's Odyssey", in which Waylon Smithers was colorized as black with blue hair.^[17]

In 1992, Gracie Films switched domestic production of The Simpsons to Film Roman from 1992 to 2016.^[18] Csupó was "asked [by Gracie Films] if they could bring in their own producer [to oversee the animation production]," but declined, stating "they wanted to tell me how to run my business."^[18] Sharon Bernstein of The Los Angeles Times wrote that "Gracie executives had been unhappy with the producer Csupo had assigned to The Simpsons and said the company also hoped to obtain better wages and working conditions for animators at Film Roman."^[18] Of the 110 people he employed to animate The Simpsons, Csupó laid off 75.^[18]

1991–2005: major success with animated series

In 1991, Klasky Csupo created Rugrats, one of the first animated shows for Nickelodeon - known as "Nicktoons" - which was inspired by the couple's two sons and the idea of what they would do if they could speak.^[19][20] Their next major series was Duckman for the USA Network, which revolved around the home life and adventures of a dim-witted and lascivious private detective duck named Eric Duckman. The series ran from 1994 to 1997. During the same time, Nickelodeon released Klasky Csupo's second Nicktoon series, Aaahh!!! Real Monsters. During this time, Klasky Csupo originally ended production on Rugrats due to the network's since-outdated 65-episode rule.^[21] However, when Rugrats went into syndication, it exploded in popularity with ratings skyrocketing and advertising deals taking off, prompting Nickelodeon and Klasky Csupo to resume production on the series. The show was cited as "a show like the Simpsons, but for children".

In 1993, Klasky Csupo worked with comedian Lily Tomlin and her partner Jane Wagner to bring the irascible little girl, Edith Ann, to television in two half-hour animated specials for ABC. The first, A Few Pieces of the Puzzle, aired in January 1994 and received critical acclaim, and the second, Homeless Go Home, aired in May 1994 to even better response and ratings.

In 1995, the studio debuted Santo Bugito, the first Saturday morning animated comedy on television. Created by Arlene Klasky and Gabor Csupo for CBS, Santo Bugito tells the story of a small town of 64 million insects located on the border of Texas and Mexico. Music-driven and Latin-influenced, the series stars Cheech Marin, Joan Van Ark, Tony Plana, William Sanderson, George Kennedy, Marabina Jaimes and David Paymer, and is highlighted by a distinctive look and the music of Mark Mothersbaugh, the Devo keyboardist who also composed the music of Rugrats.

The same year, Klasky Csupo established Klasky Csupo Commercials (rebranded as Class-Key Chew-Po Commercials in 1998), helmed by John Andrews, in order to continue the successful commercial animation business that had grown from the company's initial work in main titles and graphics. Class-Key Chew-Po had been an immediate success, building an impressive client list with work for companies like 1-800-COLLECT, Oscar Mayer, Taco Bell, Kraft, and Nickelodeon. In 2001, the company founded Ka-Chew!, a live-action commercial division.

The company was also active in producing recorded music with the record labels Tone Casualties and Casual Tonalities. Gabor Csupo was a good friend of Frank Zappa and occasionally collaborates with Mark Mothersbaugh. After Duckman and Aaahh!!! Real Monsters' were both cancelled in 1997, Klasky Csupo began producing The Wild Thornberrys for Nickelodeon, which premiered the following year; the story revolved around a girl named Eliza Thornberry who could talk to animals.^[22][23]

In 1998, Klasky Csupo produced its first feature-length film, The Rugrats Movie, which opened in the United States on November 20, 1998 as the #1 film in the country and grossed $141 million worldwide, becoming the first non-Disney animated film to gross over $100 million in the United States. It was then followed by two sequels, Rugrats in Paris: The Movie (2000) and Rugrats Go Wild (2003), the latter of which was a crossover with The Wild Thornberrys. The Wild Thornberrys later got its own feature-length film in 2002.

That same year, Klasky Csupo was commissioned by McDonald's to develop The Wacky Adventures of Ronald McDonald, a series of six animated videos featuring the company's mascot, Ronald McDonald, which were distributed directly to consumers via participating McDonald's restaurants on VHS. On December 23, 1998, CEO Terry Thoren concluded an eleven-month negotiation with the car industry Mercedes-Benz and moved the company into the state-of-the-art studio in Los Angeles.^[24]

In the late 1990s and early 2000s, Klasky Csupo began producing two more shows for Nickelodeon: Rocket Power and As Told by Ginger. They also produced the first series of Stressed Eric, BBC Two's first adult-oriented animated series.

In 2001, in honor of the tenth anniversary of Rugrats, Klasky Csupo released a two-part television special entitled All Growed Up, which featured all of the titular babies as teens.^[25] It was popular enough that Nick commissioned a series based on that special, titled All Grown Up!, which ran on the channel from 2003 to 2008. On September 29, 2001, Class-Key Chew-Po signed animation director Chris Prynoski and his company Titmouse, Inc. for commercial representation.

In 2003, Klasky Csupo and Titmouse, Inc. were commissioned by Cartoon Network to produce a music video by the band They Might Be Giants for their song "Dee Dee and Dexter", which features characters from Dexter's Laboratory drawn by the studio in anime style. Class-Key Chew-Po Animated Commercials and Broadcast Design were then folded into Ka-Chew! the following year.

Also in 2003, the studio began work on The Way the Dead Love, a theatrical film that was set to adapt seven short stories from German-American writer Charles Bukowski from a script penned by Bruce Wagner.^[26] The film was developed under the studio's Global Tantrum division, with Winchester Films being tapped to co-produce the film with the studio, as well as providing sales for the film.^[26] It was to be directed by Igor Kovalyov and Laslo Nosek, with names like Radiohead and Peter Gabriel being attached to compose the feature. Slated for a 2006 release,^[27] the year came and went without it. The project was then revived that same year at Warner Independent Pictures,^[28] with Johnny Depp being attached to co-produce and serve as the voice of the film's main character.^[29] Once again, the project was silently scrapped. Had it been completed, the film would have been the first R-rated feature from the studio.^[27]

In 2005, the company again worked for Cartoon Network on the shorts Oogloo + Anju, Food Court Diaries, and The Topside Rag for Sunday Pants under Ka-Chew!.

2006–2011: decline

In the mid-2000s, Klasky Csupo ceased production on their Nickelodeon shows, as Nickelodeon executives became tired of the studio's style of animation and soon ended their long-running partnership. In 2006, the longtime CEO of the company, Terry Thoren, left the studio and they dissolved the remainder of their 401(k) program, leading them to a period of dormancy and inactivity.

In fall 2006, Klasky Csupo announced the development of 28 new animated cartoon pilots that were to be up for sale at a later date.^[30] Each pilot was animated in different designs, instead of the typical style the studio was famous for. As of 2010, some of the cartoons had yet to be finished. Gabor Csupo would later post the remains of the cartoons on his YouTube channel. One of the pilots, Chicken Town, was picked up as a series by French company Ellipsanime, though Klasky Csupo was not involved with it.^[31]

In 2007, Paul Demeyer left Klasky Csupo to found Wild Canary, taking some of Ka-Chew!'s clients with him. In 2008, Ka-Chew! celebrated its 10th anniversary by expanding its roster of directors,^[32] before being absorbed into 6 Point Media in April 2011.^[33] In the same year, the studio released its final film to date, Immigrants, which was originally produced as an unaired animated series for Spike TV.

2012–present: return of the company with new projects

In 2012, Arlene Klasky and Gabor Csupo reopened the company after nearly four years of dormancy. Along with Craig Singer, the studio created its first new project in four years, Ollie Mongo, a digital comic book about a teenage skateboarding zombie who lives 200 years in the future.^[34] In 2015, the company announced that they were working on RoboSplaat!, a web series featuring the character with a robotic voice from their 1998 on-screen logo, given the name "Splaat" (currently voiced by Greg Cipes). The logo featuring him was retired in 2008, but was revived in 2021 along with the premiere of the Rugrats revival; the logo continues to appear on productions from the company. The web series premiered on December 21, 2016^[35] and an app based on the web series is also currently in development.^[36] That same year, Klasky Csupo also announced that they were working on some "top secret projects".^[37]

On September 2, 2015, it was announced that Nickelodeon may "seek to experiment with retooled versions of classics" that could include Rugrats.^[38] The following day, The Independent announced that Rugrats "could soon be back on our screens too".^[39] At San Diego Comic-Con in 2016, Arlene Klasky explained that she would be willing to work on a revival of the series along with co-creators Gábor Csupó and Paul Germain.^[40]

On July 16, 2018, Nickelodeon announced a revival/reboot of Rugrats consisting of a 26-episode order. Arlene Klasky and Gábor Csupó would return as executive producers for the revived series.^[41] Using CGI animation rather than traditional hand-drawn animation used in the original series, the new Rugrats premiered on Paramount+, the streaming service for Nickelodeon parent Paramount Global, on May 27, 2021.^[42]

In April 2022, Gabor Csupo launched an NFT project titled Cosa Monstra.^[43]
