Which in itself would cost a heck of a lot of money, which they simply don't have at this time. In my not so qualified opinion, they've not had a more strategic plan moving forward and stability in the schedule for many years - without serious funding they are limited to how much they can do and how much they can grow. Strategic spending and investment in the right areas might sound like some marketing spin to you or others, but that's the harsh reality for the network right now - call it cheap if you will but it is what it is.
Whilst I do agree with you on some of what you've said, the reality is that I believe (I don't agree with absolutely every decision they make, but in the bigger picture) they are doing just about everything they can to build and strengthen the network back up, retain & produce an (arguably) quality flagship news bulletin most evenings and offer a slate of new year round programming which is different & engaging than its other two commercial rivals which they can then build and expand on as finances allow.
Now, back on topic..
