..... or even many other nights?
Just reading the TV guide and from 6 pm to 10:30 pm only Pointless, Casualty and The Voice get a rating over 5.0 out of 10, and then only just - 5.5, 5.4 and 5.4. The rest don't even get above 2.0 and one, First & Last only gets 0.7.
Only C4 and C5 seem to bother, but for anything else you have to dig down into the minor channels of Freeview. No wonder Sky, Netflix, Prime, Disney, Now and so on are doing so well.
