HolbyBlue is a British police procedural television series that aired between 8 May 2007 and 5 June 2008 on BBC One. The programme was created by Tony Jordan as a spin-off from the established BBC medical drama Holby City, which in turn is a spin-off from the medical drama Casualty. All three programmes are set in the fictional city of Holby. HolbyBlue follows the professional and personal lives of police staff at Holby South police station. The show ran for two series, the first of which was eight episodes long. The second series was twelve episodes long, and began with a Holby City crossover episode. In August 2008, it was announced that the show had been axed by the BBC and would not be returning for a third series. The first series aired on Tuesday nights at 8 pm, in the regular Holby City timeslot. Holby City was moved to Thursdays for the duration of HolbyBlue's run. The show moved to Thursday nights for the second season.
