The IT Crowd is a British television sitcom originally broadcast by Channel 4, created, written, and directed by Graham Linehan, produced by Ash Atalla and starring Chris O'Dowd, Richard Ayoade, Katherine Parkinson, and Matt Berry. Set in the offices of the fictional Reynholm Industries in London, the series revolves around the staff of its IT (Information Technology) department: technical genius Maurice Moss (Ayoade); work-shy Roy Trenneman (O'Dowd); and Jen Barber (Parkinson), the department head/relationship manager who knows nothing about IT. The show also focuses on the bosses of Reynholm Industries: Denholm Reynholm (Chris Morris) and, later, his son Douglas (Matt Berry). Goth IT technician Richmond Avenal (Noel Fielding), who resides in the server room, also appears in several episodes.

The comedy premiered on Channel 4 on 3 February 2006 and ran for four series of six episodes each. Although a fifth series was commissioned, it was not produced. The series finale was broadcast on 27 September 2013. The IT Crowd was critically acclaimed and has a cult following.
