Is satire a dying art?

I appeared on Radio 4 a couple of weeks ago to discuss the age-old question of whether political satire is dead. I don’t think it is, but it has lost a good deal of vitality in recent years and the role of satire in the general election campaign is a case in point. There has been no shortage of ‘satirical’ television programmes, but none of them have cut through. The only sign of life has been the flurry of photoshopped images on Twitter that have followed each misstep of the parties’ campaigns, such as Ed Miliband’s decision to carve Labour’s election pledges on to an eight-foot stone slab. If Stanley Kubrick was still alive he’d be suing people for illegally reproducing images from the opening scene of 2001: A Space Odyssey.

What accounts for satire’s declining health? I don’t hold with the textbook explanation, which is that standards in public life have sunk so low that nothing a satirist could come up with could be as bad as the reality.
