Since then, "Return of Nick Cotton" (2000), "Ricky & Bianca" (2002), "Dot's Story" (2003), "Perfectly Frank" (2003) and "Pat and Mo" (2004) have all been broadcast, each episode looking into lives of various characters and revealing part of their backstories or lives since leaving EastEnders. In 1993, the two-part story "Dimensions in Time", a charity cross-over with Doctor Who, was shown.
  In 1998, EastEnders Revealed was launched on BBC Choice (now BBC Three). The show takes a look behind the scenes of the EastEnders and investigates particular places, characters or families within EastEnders. An episode of EastEnders Revealed that was commissioned for BBC Three attracted 611,000 viewers. As part of the BBC's digital push, EastEnders Xtra was introduced in 2005. The show was presented by Angellica Bell and was available to digital viewers at 8:30 pm on Monday nights. It was also shown after the Sunday omnibus. The series went behind the scenes of the show and spoke to some of the cast members. A new breed of behind-the-scenes programmes have been broadcast on BBC Three since 1 December 2006. These are all documentaries related to current storylines in EastEnders, in a similar format to EastEnders Revealed, though not using the EastEnders Revealed name.
