Blackadder

Blackadder was an Earth comedy deemed to be of merit by the Doctor's Five Hundred Year Diary.

According to the Doctor's Five Hundred Year Diary, The Doomsday Contract did not make it to television because John Lloyd's interests "had instead moved on to spearheading every single Earth comedy of merit that would appear over the next three decades", which apparently had "little to no impact on his standing with the association of tennis professionals". These Earth comedies included Blackadder, Spitting Image, and Not the Nine O'Clock News. (NOTVALID: Tom Baker stars in John Lloyd's lost Doctor Who adventure, The Doomsday Contract)

Behind the scenes
The title character (or 'characters') of the show, "the Black Adder", was portrayed by Rowan Atkinson, who also portrayed a version of the Ninth Doctor in 1999's TV: The Curse of Fatal Death. Incidentally, that same year saw the production of Blackadder: Back and Forth, featuring a Blackadder who invented a box-like time machine.

Blackadder also featured Brian Blessed as King Richard IV, Tom Baker, and Stephen Fry. The Christmas special Blackadder's Christmas Carol featured Miriam Margolyes and Jim Broadbent, both of whom had played other roles in the television series, appearing respectively as Queen Victoria and Prince Albert, as well as Nicola Bryant.

Much like Doctor Who, Blackadder was a television series created by the BBC.
