The segment creators include David Fain, Tim Hill, Steve Holman, Emily Hubley, Mark Marek, Mike Pearlstein, Mo Willems, and Cote Zellers. The theme song and all of the original background music on the show was provided by the Moon Ska Stompers, a band composed of King Django, Victor Rice, and members of The Toasters and The New York Ska-Jazz Ensemble. The bulk of the soundtrack was 30-second instrumental clips of songs from The Toasters' album D.L.T.B.G.Y.D., while the theme song itself is a shortened version of the Toasters song "2-Tone Army". Tracks from the Associated Production Music library were also utilized.

KaBlam! was the first show to be spun off of All That. It was pitched to Nickelodeon in 1994 and aired two years later. Some of its shorts were originally stand-alone shorts during Nickelodeon commercial breaks. The pilot episode, "Your Real Best Friend", was created in 1995 and finished in 1996. In 1996, The Off-Beats, one of the many shorts on the show, were released on a Rugrats videotape entitled "Tommy Troubles."

The show began production in 1996 and premiered October 11. The show ran for four seasons. The last episode was broadcast on May 27, 2000. Reruns CONTINUED to show on Nickelodeon until 2001. In 2002, Nicktoons was launched, and the channel began airing reruns of the PROGRAM, though not all episodes were aired. During commercial breaks, various shorts from the show would play, not including any shorts involving Henry and June or music videos. In August 2005, Nicktoons changed its appearance and schedule, and canceled many shows in the process, including KaBlam!. After the show was cancelled, the "KaBlam! Presents:" shorts would continue to be shown, until 2008 when the channel did away with all of their in-between shorts, for more commercial space. The program hasn't been shown since then until 2016, not even when Nick had a marathon of the first episodes of each Nicktoon on Thanksgiving Day 2007, despite having Henry and June on the cover of the now-defunct Nickelodeon Magazine. It reaired on The Splatlight night in October, airing only Your Real Best Friend, It's Flavorific, and Not Just For People Anymore.

A French-dubbed version has been broadcast in France on television channel GameOne and other versions of the show are on other Nickelodeon channels around Europe.It also was shown in the United Kingdom from 1997 to 2000, and in Poland from 1999 to 2002. The show played onYTV in Canada.
