Which BBC channel aired The Office (UK) Christmas specials?

The Office (UK) Christmas specials aired on BBC One.

The two-part specials were broadcast in the United Kingdom on 26 and 27 December 2003. The regular series had originally aired on BBC Two, but the Christmas episodes were moved to BBC One to reach a larger audience after the programme’s growing popularity.

The specials served as the sitcom’s series finale after creators Ricky Gervais and Stephen Merchant decided not to make a third full series. Their documentary-style story revisits the Wernham Hogg employees after the events of Series 2, including David Brent’s failed post-redundancy career and Tim Canterbury’s continuing relationship with Dawn Tinsley.

This scheduling change is a common source of confusion: BBC Two was the home of the first two series, while BBC One carried the Christmas conclusion. The move worked commercially, with the first part attracting more than seven million viewers and the second more than six million.
