...and all broadcasters would be proud of their regions.
May be there'd be some in-vision continuity. If it was done from "around the region" it would give viewers a reason to watch.
I'm not sure at the end of the day it would make any difference.
Granada used to use loads of in-vision continuity, but it didn't stop Granada Media from axing it and sending it out of vision across the pennines.
So if Central wasn't purchased by Carlton, they'd probably still end up dropping the cake logo in the end etc.
Also its not the 'organisation' which makes these decisions, its the people within them, presumably the bloke who retained Granada's in-vision retired or moved on, and his replacement didn't want it so axed it, and the rest of the board didn't care either way
Look at Bruce Gyngell, the whole Channel 3 North East debacle seemed to be his doing, not known before his reign, and scrapped soon after
