Ben 10 was created by "Man of Action" and was produced by Cartoon Network Studios. Man of Action is a group consisting of comic book creators Duncan Rouleau, Joe Casey, Joe Kelly, and Steven T. Seagle. The group worked on Ben 10's concept roughly 3 years before Cartoon Network picked up the series. Dave Johnson also helped in the design development.[4]

Early on in development, it was decided that a villain would be within the Omnitrix. After Ghostfreak was created the creators added dialogue into the first season to give the audience that there is something more to Ghostfreak.[5] Originally Cannonbolt the 11th alien transformation in the series, was going to be in the original set of aliens, but was replaced with Ghostfreak.[5]

When doing test animations for the series the first alien transformation to be tested was Four Arms. It was the most popular transformation out of all the aliens for "Man of Action".[5] Many of the unused designs for Upchuck were recycled in the episode "Ben 10,000" as two of Ben's aliens "Spitter" and "Articguana", and as villain Sploot.

Steven E. Gordon worked on an early version of the show. His concept work reveals that Ben Tennyson was originally going to be a red-headed young boy. Gordon also has early designs of the Omnitrix which look more like a watch than the final version, as well as different designs and names for the alien transformations.[6] Some of the early names for the transformations were "StrongGuy", "Inferno", "RazorJaws", "Dragonfly", "Plantguy", and "Digger". Some of the early designs for the aliens are more human and superheroic, similar to Dial H for Hero.[6]

Sunmin Image Pictures, Dong Woo Animation and Lotto Animation, Inc. contributed some of the animation for this series.

The theme song for the series was written by Andy Sturmer and sung by Mz. Moxy.[7] The main title were created by Renegade Animation, who was well known for Hi Hi Puffy AmiYumi, which was created by Ben 10's executive producer Sam Register. The flash animated sequence during the main title was designed to let the audience know that the show is going to be fun and not just an action show.[8] The opening credits were altered in the third season and beyond to reflect that Ghostfreak was no longer to be used, and was replaced by Cannonbolt as the ninth alien.

Kris Zimmerman was in charge of casting and was the voice director. Tara Strong voices the title character Ben Tennyson, Upgrade, Benwolf, Lucy Mann-Tennyson, Ken Tennyson, and Sandra Tennyson. She also voices Future Gwen and Buzzshock in "Ben 10,000". Meagan Smith voices Ben's cousin Gwen Tennyson, and Paul Eiding voices Grandpa Max and his version of Upgrade.

Steven Blum voices Ben's alien transformations Heatblast and Ghostfreak, as well as the series' main villain Vilgax. Dee Bradley Baker voices Ben's transformations Stinkfly, Eye Guy, and Wildmutt, Baker also voices Ben's school bully/friend Cash Murray, and many of his enemies such as The Limax, SixSix, Acid Breath, and the character Elsgood. Baker is also notable for voicing various characters and aliens. Richard Steven Horvitz voices Ben's Grey Matter transformation and the villain Sublimino. Richard McGonagle voices Ben's Four Arms transformation, and the villain Exo-Skull. Fred Tatasciore voices Ben's aliens Ripjaws, Cannonbolt, and Way Big, Tatasciore also voices a future version of Ben in "Ben 10,000". And Jim Ward voices the transformations Diamondhead, XLR8, and Wildvine, and the character Gordon Tennyson.

Two Ben 10 films have been released at different times during 2007 and 2008. The first is a regular animated feature called Secret of the Omnitrix, in which the Omnitrix is accidentally set to self-destruct and Ben must track down its creator to stop it. A trailer of the film was released with the film Billy & Mandy: Wrath of the Spider Queen, and it aired August 10, 2007. Michael Ouweleen described the film's villain, which was actually Vilgax, as "like Darth Vader without the sense of humor."[9] A different version of Secrets of the Omnitrix, which introduced a different alien (Eye Guy) to the one in the original (Heatblast), aired on September 1, 2007. A third version (in which XLR8 was featured) aired on October 20, 2007. It was stated during the premiere of Alien Force that Secret of the Omnitrix was intended to be the chronological finale of Ben 10, even though it was broadcast long before the last episode, which was not canon.

A CGI movie titled Ben 10: Destroy All Aliens was first released on March 11, 2012, in Asia[10] and on March 23, 2012[11][12] in the US. The movie focuses on a 10-year-old Ben returning to school after the summer.[13][14] The movie was released in 2 different versions on Asia. The Filipino viewers heard the Philippine winners while the rest of Southeast Asia heard the Malaysian kids.[15]

Ben 10: Race Against Time is the first film in the series. It revolves around Ben (Graham Phillips), Gwen (Haley Ramm) and Grandpa Max (Lee Majors) returning to their hometown of Bellwood and attempting to adjust to being ‘normal’ again. Unfortunately, their lives are once again disrupted by a mysterious alien known as Eon (Christien Anholt), who has an unexpected connection to the Omnitrix.

Ben 10: Alien Force is the sequel to the show set five years after the original series. As an indirect result, this series is darker in tone compared to its predecessor. The series premiered on Cartoon Network on April 18, 2008, and ended on March 26, 2010. It has since been premiered in Canada, on Teletoon.[16] A video game of the show is now out for the Nintendo DS, Wii, PlayStation 2 and PlayStation Portable.[17]

Another sequel series, Ben 10: Ultimate Alien, premiered on April 23, 2010, and takes place 3–4 weeks after the finale of Alien Force.[18]

Ben 10: Protector of Earth is the first Ben 10 video game, released in autumn 2007.

Following the success of the Ben 10 animated TV series and films, various Ben 10 merchandise has been released for general sale. These items include Ben 10 books, action figures, card games such as Top Trumps, toys, video games – notably Ben 10: Protector of Earth, bedding, and footwear.

Ben 10 appears in Cartoon Network's online MMO FusionFall. The character design for Ben Tennyson was changed when the original Ben 10 series ended and was replaced by Ben 10: Alien Force. In the game, he serves as a "Player Guide" offering guide-based missions and special items that can only be used with certain guides.
