Are there any shows which have killed a comedy genre dead or at least knocked it out cold?
A good example would be Trigger Happy TV. Since then there's been very little hidden camera shows which were any good. This is, in my opinion, because Trigger Happy TV was so good there's no point making something similar. Day Today and Brass Eye are two other shows which have done this.
Then on the shite side of the spectrum we have shows that are so crap, predictable and 'safe' that they breed comedy offspring like rabbits. E.g. Little Britain begat Catherine Tate Show (I know it was before but who cares), Titty Bang Bang, Adam and Shelly, Marc Wooten. Basically every rubbish thing BBC Three produce that isn't Two Pints.
Then in the middle we have the slow burners such as, I would argue, The Young Ones leading indirectly to the Mighty Boosh via several Reeves and Mortimer shows.
So which shows either kill off the genre, ruin the genre for everyone or keep the genre going?
