EastEnders
"EastEnders" is often filmed on location, away from the studios in Borehamwood. Sometimes an entire quartet is filmed on location, which has a practical function and are the result of "EastEnders" making a "double bank", when an extra week's worth of episodes are recorded at the same time as the regular schedule, enabling the production of the programme to stop for a two-week break at Christmas. These episodes often air in late June or early July and again in late October or early November. The first time this happened was in December 1985 when Pauline (Wendy Richard) and Arthur Fowler (Bill Treacher) travelled to the Southend-on-Sea to find their son Mark, who had run away from home. In 1986, "EastEnders" filmed overseas for the first time, in Venice, and this was also the first time it was not filmed on videotape, as a union rule at the time prevented producers taking a video crew abroad and a film crew had to be used instead. In 2011, it was reported that eight per cent of the series is filmed on location.
BBC Three
Numerous popular series were either repeated on the channel or have spin-offs created from them. In early 2003, viewers could watch episodes of popular BBC soap opera "EastEnders" on BBC Three before they were broadcast on BBC One. This programming decision coincided with the relaunch of the channel and helped it break the one million viewers milestone for the first time. An episode of "EastEnders Revealed", which was commissioned for BBC Three and looking behind the scenes of the programme, attracted 611,000 viewers. In 2005, BBC Three commissioned the documentary series "Doctor Who Confidential", which was shown immediately after episodes of the new series of "Doctor Who" had been screened on BBC One. This was followed up in July 2005, when it began to screen repeats of both programmes.
