"Faith of the Heart"). Some of the most prominent composers of 20th- and 21st-century film music have written film scores and television scores for Star Trek. These include Jay Chattaway, Cliff Eidelman, Michael Giacchino, Jerry Goldsmith, James Horner, Dennis McCarthy and Leonard Rosenman. A subgenre of Star Trek fandom has developed, specifically for the music of Star Trek, which includes music lovers who are not otherwise interested in Star Trek fandom. Dozens of commercially produced musical recordings of performances of Star Trek music exist—unrelated to the performance of screen Star Trek itself—evidencing the intrinsic cultural value and influence of the music of Star Trek. A concert series, Star Trek: The Music, by Erich Kunzel and the Cincinnati Pops Orchestra, played in several US and Canadian cities between 2007 and 2010. Science fiction, fantasy and television The first television series with comparable storyline and set-up to Star Trek (aside from the genre rival Doctor Who) was the 1990s series Babylon 5. When pitching the series, the producer J. Michael Straczynski had hoped that television executives would think Trek had opened up the market for science-fiction on television. However, he was told that Star Trek only created a market for more Star Trek and that the prospects for non-Trek related science fiction were seen as bleak. Eventually, Babylon 5 was greenlit. Three script writers who had worked for the original Trek series were to write for Babylon 5 (including D. C. Fontana who had written for three different Trek series), and Star Trek actor Walter Koenig was cast in a recurring role. All this, and the strong similarities of the series' premise to Star Trek: Deep Space Nine invited comparison to Star Trek. In addition, Babylon 5 was the first television series since Star Trek to get nominated for or win the Hugo award for best science fiction drama, which had only recognized feature films in the media category since Star Trek. Gene Roddenberry's widow and Star Trek actress, Majel Barrett-Roddenberry, publicly stated that her decision to do a guest star appearance on Babylon 5 was to stop the feuding and bickering among hardline fans of the two series, which broke out occasionally at science fiction conventions. Ultimately, the series ran for its intended length of five seasons, making it the longest running American space oriented futuristic television series outside of the Star Trek franchise.
