This is all a bit of a pitiful nonsense. The BBC is, to a degree, recession proof. Yes, it's had its budget frozen, but it has been wasting money through a combination of self-indulgent projects and simple wastefulness and mismanagement for years.
Comedy always seems to be regarded as some kind of optional extra. Well it isn't. Comedy was one of the key reasons that BBC radio, and later television, became such a massive success. It is not a financial burden when compared with drama, live sport or news gathering. The prejudice that some in broadcasting have against comedy is that it is a hard genre to satisfy an audience with, that it requires great skill to make, and that management is generally ill-equipped to understand and shepherd comedy well (even those with the word "comedy" in their job title). Far, far easier and safer to spend the cash on another generic cop drama, or a banal reality show.
And cutting the number of shows won't, perversely, improve the quality of those which are selected. That's not how TV works. The standard will actually diminish.
