Information from invalid sources
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. (WC: )
