Night and Day is a British mystery soap opera, produced by Granada Television for LWT, that first broadcast on 6 November 2001 on ITV, and ran until 5 June 2003.

The series was written and created by screenwriter Caleb Ranson, with other contributors to the series including John Jackson, Jessica Townsend, Cris Cole, Elizabeth Delaney, Jeff Dodds, Robert Fraser, Adrian Hewitt, Martha Jay, Charles Lambert, Ed McCardie, Adrian Pagan, Bradley Quirk, Tony Ramsay and Catherine Stedman.

However, as the series storylines became more bizarre and complex, it began to rate poorly, only gaining a small, cult fanbase, and was pushed to a later timeslot due to the lack of mainstream interest.

Over the next year, the lives of six families in the street become further intertwined as a tangled web of secrets and lies threaten to boil to the surface, and Jane's disappearance continues to have a devastating effect.

The episode then flashed forward to four years later and looked at one day in the very different lives of the residents of Greenwich, as Jane was seemingly released from prison and came to discover what had happened since.

Speaking of the decision to axe the teatime episodes, Tony Woods, then head of continuing drama at ITV, stated that "The series has already established itself as cult viewing for young adults, and re-positioning it with a debut broadcast in the evening will build on its appeal".

It originally aired at 6pm on weeknights, as a lead into the evening news, but the later episodes were predominantly screened very late at night, in a similar fashion to the UK broadcast; although these retained the thirty-minute format.

[citation needed] With the loss of Home and Away to Channel 5 in early 2000, the ITV network centre decided to tender bids from various UK production companies for a new British soap to replace it.

[4] Further in to development, the working title of the series change to "Trafalgar Road", which was later abandoned due to an existing street having that name in the filming location of Greenwich.

The sheer number of songs used on the soundtrack throughout the series would make a DVD release financially impractical as each artist would need to be paid a royalty fee.
