I would like some fresh ideas, and a return to a proper full 6 hours.
Good Luck with that. But, I'd like to draw your attention to two minor points.
1 - 'Fresh Ideas'. A total vauge meaningless phrase. And even if someone came up with a 'fresh idea', whoever created it will have subconciously used part of an existing format.
Try it - pitch something you'd thought of that is totally new, fresh, orginal and has not been tried, used (in full or part) in the UK or anywhere in the world before. Difficult, isn't it?
2- Create a schedule to run a full 6 hours? And who, in this modern multi-channel fragmenent market and audience age is going to watch an 'appointment to view' schedule for a full 6 hours in one go? At most 2 hours and then bail out and cherry pick and timeshift the rest of it.
If you asked the question, the honest answer is less than 0.1% of the audience.
Although, as programme junctions are your thing - you'd probably like a schedule for 6 hours, with upto 6-8 idents, so you could come on here and bitch about how they've reused a ident 3 hours after it was last aired.
