I know money is the key priority to them, and they're bound to lose money by closing channels. But seriously, in my opinion, it just cheapens the UKTV brand when they have programmes on channels that really shouldn't be there. And my stance probably won't change until I stop seeing The Two Ronnies on a channel dedicated to history documentaries.
In all fairness though, that sort of situation has occurred before on other networks and tends to be trend related. Music channels are a good example of this when MTV and friends cut back dramatically on actually airing any music in favour of cheap reality crap. The sister channels did move back towards music eventually though, whereas MTV has pretty much committed itself to anything but music.
Pretty much like 4Music really, which is effectively E4 in different colours these days. Why they don't just rebrand the damn thing I really don't know as I can't remember the last time it played any music.
