I think that BBC regional news has always been terrible for not being consistent even within a single region.
There was a time when the main 18:30 Midlands Today had a weekly feature (possibly on Wednesdays?) called "Newsmakers", which would be a story being covered due to a viewer phoning in to say they had a story (often community / human interest bibble).
IIRC, the "Newsmakers" feature was first introduced during MT's final ever non-generic style circa 1999 (the gaudy multi-coloured "stained glass window / patchwork quilt" era). The story would be prefaced with a "Newsmakers" sting in that colourful style.
The "Newsmakers" sting was NEVER updated to match the subsequent Lambie Nairn "maps" era branding of the programme. The old-style sting continued to be used well into the "maps" era, despite it matching nothing else. I think that the whole "Newsmakers" feature ended by the time that Generic Look Mk2 arrived (China Red etc), so we were thankfully spared from a two-revamps-ago sting still being in use.
This kind of p*ss-poor (lack of) sense of "branding" is something that one inherently associates with BBC regional news as a whole.
I'm still a European.
