When Butch Hartman first developed the idea for a new show, it was originally titled "Danny Phantom and the Spector Detectors", and it was supposed to be a show about a young (human) ghost fighter and a team of others who hunted and fought ghosts. However, Hartman later determined it would be cooler if the teen was a ghost, thus changing it just to "Danny Phantom". Among the other ideas that were considered before being rejected was the existence of a telepathic connection between the characters Danny and Samantha. He reunited with Tara Strong, Rob Paulsen, Grey Delisle, Jim Ward, Daran Norris, Dee Bradley Baker, and Susan Blakeslee, along with Guy Moon and Bob Boyle, who did most of the voices on his other show. The designs were helped by veteran character designer Stephen Silver, helping Hartman adding his own touches. All Danny Phantom characters have necks and five digits on each hand. The majority of the stories are usually written by Steve Marmel with input from Mark Banker, Butch Hartman, Marty Isenberg, and Sib Ventress. As with Hartman's show The Fairly OddParents, the music for Danny Phantom was written by Guy Moon. It has also been stated that the theme song was inspired by Queen's 1989 song "The Invisible Man". Only 53 episodes have been purchased by Nickelodeon. On January 24, 2006, Nickelodeon announced that it has ended support for new episodes of the series. Butch Hartman has said that although no new episodes would be made, the show would still continue to be broadcast "for years to come". Fans of the show expressed outrage at the cancellation, citing Butch Hartman's admission on his forums that he wished to create more episodes, however his initial public statement on his personal forum that though he is willing to make more episodes if the show is picked up again. The series ended with the episode Phantom Planet. The show premiered on Nicktoons Network on June 1, 2007.
