Coupling is a British television sitcom written by Steven Moffat that aired on BBC2 from May 2000 to June 2004. Produced by Hartswood Films for the BBC, the show centres on the dating and sexual adventures and mishaps of six friends in their thirties, often depicting the three women and the three men each talking among themselves about the same events, but in entirely different terms.

The series was inspired by Moffat’s relationship with producer Sue Vertue, to the extent that they gave their names to two of the characters. Coupling is an example of the “group-genre”, an ensemble show that had proven popular at the time. Critics compared the show to the American sitcoms Friends and Seinfeld.

The critical reaction was largely positive, and the show was named “Best TV Comedy” at the 2003 British Comedy Awards. The show debuted to unimpressive ratings, but its popularity soon increased and by the end of the third series the show had achieved decent ratings in the UK. The series began airing on PBS stations and on BBC America in the United States in late 2002 and quickly gained a devoted fanbase there as well. The show is syndicated around the world. Short-lived American and Greek adaptations were briefly produced in 2003 and 2007 respectively.

Rachel Carson, a best-selling crime novelist, is devastated and filled with guilt over the accidental death of her son. Hoping that a change of scenery will help alleviate her suffering, she leaves her home in the city and moves into a vacant country house owned by a friend and begins a relationship with charming local Angus. But, just as her life is taking a turn for the better, Rachel realizes she’s being romanced by a ghost, leading her to doubt her own sanity.
