Agreed, now it feels like it is aiming for a higher demographic, but some programmes lean towards a younger demographic, which makes it feel a bit lost in the middle. I think they are now trying to rejuvenate it to become a more older skewing channel, with some programmes for younger viewers.
When the main TV channels eventually close down, C5 will inevitably be the first.
