I believe the local ident package used by Yorkshire was introduced for all programming shortly before the hearts package, so I imagine when Granada imposed the hearts package on them they were allowed to keep their package for local programming given how new it was and the investment that would have gone in to the it. Here's a video of the complete package:
I'm 99% certain that local Yorkshire ident package didn't appear on screen prior to the hearts, or before network programmes – IIRC, it launched at the same time as the hearts.
I do remember reading (probably on here) though that the intention was that the package would be used across the board for every junction - hence why they made so many of them (as seen here
). But then the hearts came along after they'd been made, and they were relegated to local junctions.
I have heard that Yorkshire's package was intended to be used across all the GMG north regions before the decision was made to use the hearts package instead. A christmas version of this package was used across all the GMG north regions after the hearts were introduced, can't remember which year exactly, but I want to say 1999.
There were versions of the same spinning cut-out logo background used for regional trailers for Tyne Tees and Granada, plus an image has been posted of an unbroadcast LWT one. Not sure if there were idents made in the same style for them.
I do though remember seeing an image of an unused Granada ident from around the same time with an updated logo, designed by YTV's in-house graphics department. From memory, the classic 'Giro G' had had the vertical stroke of the arrow removed, so it looked a bit like a G with a circumflex accent over it. I can't find it anywhere though - has anyone got a copy to prove I'm not going mad?
