Quite frankly MOST British shows are short lived although they may not be very well known to Americans. Looking at comedy:
Monty Python’s Flying Circus (1969) is well known but still only managed 4 seasons, 45 episodes, the final season without John Cleese and only the first 2 seasons are really “pure” Python. And that show’s the outlier!
Monty Python alumni (John Cleese) went on to do Fawlty Towers (1975) which had 2 seasons of 6 episodes each.
Meanwhile does America know Ripping Yarns (1976)? The Pythons Michael Palin and Terry Jones spoof boy’s literature of the 1920s and managed 2 seasons. One of 6 episodes and the second “season” just 3 episodes.
Eric Idle did Rutland Weekend Television (1975) spoofing a small TV station. Managed 2 seasons, the first 6 episodes the second 7 episodes. However one sketch took off. A clear spoof of the Beatles, the Rutles led to a fake TV spinoff film and album with involvement by long time Python fan and supporter George Harrison.
More recent but I’m guessing less well known to Americans would be
The Day Today (1994). Spun off from a radio show, it lasted one season of 6 episodes. It was a sketch show parodying modern news reporting. It won numerous comedy awards and introduced to the (UK) mainstream the Alan Partridge character.
It’s main creative force was Chris Morris who went on to do Brass Eye (1997) which also lasted one season of 7 episodes. This show parodied investigative TV journalism and gained notoriety in the UK when various celebrities were duped into recording pieces condemning, for example, fake drugs. The celebrities and politicians solemnly intoning the dangers…
Morris then did one season, 6 episodes of the challenging Jam (2000) which occupied a strange area somewhere between comedy, surrealism and horror.
Back to The Day Today and the character of Alan Partridge (portrayed by Steve Coogan) was successful leading to 6 episodes of Knowing Me, Knowing You (1994), 2 seasons of I’m Alan Partridge (1997 and 2002), a book and later a film Alan Partridge: Alpha Papa (2013.)
But Coogan also did 2 seasons, 13 episodes of Saxondale about a former roadie turned pest controller (pest exterminator.) That was 2006.
Coogan’s production company also got behind the Julia Davis 2004 black comedy Nighty Night about an incredibly self centred woman who sees her husband’s terminal cancer as an opportunity to start an affair with her next door neighbour’s husband. The usual 2 seasons and 12 episodes.
Then there was The Office (2001) which is a good example of the British way versus the rest of the world. The original UK version ran for just 14 episodes from 2 seasons of 6 episodes and a 2 episode Christmas special. Took a while to take off (as it were) but was incredibly successful when Ricky Gervais ended it. The US version ran to over 200 episodes and 9 seasons plus there are many, foreign versions, which have lasted longer than the UK version.
Gervais also did Extras (2005) for 2 seasons and 13 episodes and recently he did Derek (2012) for 2 seasons and 14 episodes and Life’s Too Short (2011) which only went to 1 season of 7 episodes.
One more. **The Inbetweeners **(2008) ran for a mighty 3 seasons and 28 episodes before spinning off 2 cinema released films. Interestingly this one was remade by the Americans (2012) but failed to go beyond one, 12 episode season.
There are many more shows I could name but I guess they would be increasingly obscure for the US readers so I’ll stop there. However I must point out all of the shows I have mentioned here were critically acclaimed, award winning if not outright popular hits on UK Television. Indeed many have been remade or have been considered for remaking for US and other foreign markets. It’s the UK way.
