Origin and development On February 16, 2005,
Kids' WB's unveiling of its new fall schedule for the
2005–2006 television season was announced by
The WB Television Network, featuring its returning series
Yu-Gi-Oh!,
Pokémon,
The Batman, and
Xiaolin Showdown, alongside four new series:
Loonatics Unleashed, ''
Coconut Fred's Fruit Salad Island!, Transformers: Cybertron, and Johnny Test''. The aforementioned schedule was announced by The WB/Kids' WB Entertainment President David Janollari, Kids' WB Senior Vice President and General Manager Betsy McGowen, speaking to advertisers and the media press during the Kids' WB
upfront sales presentation in New York.
Johnny Test was created and executively produced by
Scott Fellows, who also created the
Nickelodeon live action series ''
Ned's Declassified School Survival Guide and would later create Big Time Rush, and 100 Things to Do Before High School; Fellows had also served as the head writer for The Fairly OddParents''. The show premiered on September 17, 2005, on Kids' WB's
Saturday morning lineup of its weekly fall schedule, alongside
Loonatics Unleashed and ''Coconut Fred's Fruit Salad Island!''. The episode pair "Johnny to the Center of the Earth" and "Johnny X" marked the series premiere. When the show first aired on Kids' WB, it performed very well in the Nielsen ratings. It ranked as the #1 broadcast program in Boys 2-11 (garnering 2.4/11), ranked as the #2 broadcast series in Kids 2-11 (gaining 2.2/10 in the process) and Girls 6-11 (2.3/11), and ultimately ranking #3 in Kids 6-11 (receiving 3.0/14). Its second season averaged slightly more viewers in the United States: 2.6 million per episode. Its 3rd season's average number of viewers in the United States was 3.1 million viewers. Its 4th season got an average number of about 4.3 million viewers per episode in the United States. Its 5th premiere attracted over 4.7 million viewers in the United States. The series was developed for television by
Aaron Simpson, with a brief, slightly longer pre-existing pilot short produced by Simpson as well, before the show was picked up as a full series by Kids' WB. Based on Episode 1A "Johnny to the Center of the Earth", the pilot episode was animated roughly in
Adobe Flash, but retaining the same plot, used the same color schemes as the aforementioned episode, and was recorded with an American voice cast (retaining
James Arnold Taylor as the voice of Johnny Test) instead. The original production design (including character designs, prop designs, and backgrounds) was created and provided by
Matt Danner and Marc Perry, and later refined by producer
Chris Savino and art director Paul Stec at season 1. Fellows, the creator of the series who had interested the network in the series' premise, based the titular character on himself when he was a young boy; he based Johnny's twin sisters, Susan and Mary, on his own two sisters, also named Susan and Mary. In the original pilot and early promotional material of the show, Dukey was referred to as "Poochie". James Arnold Taylor said that he was not Fellows' original choice for the role of Johnny Test; he had previously voiced the lead character in the initial test pilot. After the show got picked up by Kids' WB! as a series, he was initially going to be replaced by a different voice actor, with a Canadian voice cast instead, but the studio had trouble finding Johnny's initial voice convincing for the first six episodes, so they gave Taylor back the role to redub his dialog for the rest of the first season and managed to keep him on the cast for the rest of the series. Chris Battle, Casey Mitchum, Pat Ventura,
John Derevlany, J.C. Cheng,
Aliki Theofilopoulos, George Cox III, Frederick J. Gardner III, Allan Penny, Justin Schultz, Christopher D. Lozinski, Dane Taylor, and Rita Cooper. The original version of the show's
theme song and all of its
underscores were both written, composed, and conducted by
Kevin Manthei, with creator Scott Fellows having written and provided the
lyrics to the theme song.
Voice recording was provided by
Voicebox Productions, with voice direction by
Terry Klassen. The merger of
UPN and
The WB into
The CW Television Network resulted in significant budget cuts for the show, placing it on hiatus.
Cookie Jar Entertainment, another Canada-based entertainment company, under their then-new action-adventure brand Coliseum, who previously had production assistance in the first season, decided to take control of the series' production. Due to this change, the writers, storyboarders, and art crew who worked on the first season were let go, resulting in an entirely new crew managing the show. As the budget of the show dropped dramatically, seasons two and three of the show were animated in
Adobe Flash by
Collideascope Digital Productions. The show's opening theme was later changed for the rest of the series, with it being made of recycled episode footage. On March 1, 2008, the episode pair "Johnny X: A New Beginning" and "Johnny X: The Final Ending" aired. It was originally intended as the series finale; however, the series was later picked up by Cartoon Network for a fourth season. Although Warner Bros. left the series' production, the trademark of Johnny Test still remains at Warner Bros. The fourth season was animated at
Atomic Cartoons with animation assistance from Seventoon Inc. and Philippine Animators Group Inc., which are both located in the
Philippines. It finally premiered in high-definition on Teletoon on September 10, 2009, and on Cartoon Network in the U.S. on November 9, 2009. Later, on August 24, 2010, it was announced that the
Johnny Test was renewed for a fifth season. As the fourth season before it, it would be a full set of 26 episodes with a 27th episode added to the end; the renewal brought the series total to 92 episodes. The fifth season premiered on Cartoon Network in America on June 13, 2011, along with a new theme sequence with the same song used from seasons 2–4. Starting with the fifth season, Trevor Devall would become the new voice of Dukey, due to Louis Chirillo leaving the series. Similarly, Ashleigh Ball retired as the voice of Mary, Sissy, and Missy at the end of the 4th season, due to her work on
My Little Pony: Friendship Is Magic as the voice of Applejack and Rainbow Dash; as a result, she was replaced by Brittney Wilson, Mary's original voice. On March 12, 2012, it was announced that the show had been renewed for a sixth season. Like the fourth and fifth season before it, it would again be a full set of 26 episodes; the renewal brought the series total to 117 episodes. Ashleigh Ball also returned for the roles in this season. The sixth season premiered in the United States on
Boomerang on April 3, 2013, and on Cartoon Network on April 23, 2013. With this season, the show reached its 100th episode (and 200th segment), making it one of Teletoon's longest-running original series (
Total Drama had produced 117 episodes and two specials, while
Totally Spies! was co-produced between seasons 3–5). ==Revivals==
