I should clarify that Line-up graphics are different to a Next Promo. They’re run at different times.
Line-up graphics and station idents were typically run in between two programs, where as the “NEXT” & “LATER” graphics are typically run at the tail end of an ad break.
Nine still run “NEXT” promos in their ad breaks.
What I was referring to specifically is the junction point between programs. In the past these used to be on the hour or half hour. It was were people used to change the channel for different shows and you could set your watch to it on the ABC. These are where idents and line-up signposts used to run. In pre-digital and pre-watermark days, idents also confirmed which channel you’d tuned into.
These days junctions, however, aren’t as strict or obvious anymore and it’s done on purpose. If they’re noticeable it distracts people, makes them realise they have an opportunity to change channel and that they don’t actually have to watch anymore.
I personally like it a lot better when one program flows from one to the other, and it actually makes me watch shows I may not choose to watch otherwise.
A channel’s brand is shown in after-break animations, watermarks and station promos in ad breaks too, it’s not exclusive to an ident. Consistent ratings throughout the night and audiences attract advertisers more than an ident will.
Have you ever tried to organise a station’s pool of talent to turn up on a single day to shoot such an exercise? Add in planning, scripting, shooting, graphics, editing, post production audio, colour grading, approvals, etc etc.
It’s not a cheap exercise, especially when there’s actually no financial return to having them - the promos they produce now already advertise the shows these personalities are on and, where the block is concerned, have sponsors attached.
I don’t think a decent line up will work in flash frames like that. Plus they’re actually illegal, quite irritating and costly - just as ten about the Aria awards a few decades ago.
