On t'other side, they don't say "this is BBC News Midlands Today", it's "Welcome to Midlands Today from the BBC" so why can't ITV badge their regional news programmes more sensibly, e.g. "This is Central News, part of the ITV Network" ?
Erm... because the
names of the programmes actually are e.g. "ITV News Meridian" etc, as is clearly how the programme names are written on-screen!
Conversely, the BBC regions' logos clearly aren't meant to be read literally (or else the official programme names would be e.g. "BBC South Today BBC News" etc, which is clearly way too daft to be the intention).
The ITV regions' logos
have "ITV" (and/or "ITV News" ) written on screen twice simultaneously. Granted, the standardised title form can be a bit cumbersome and inelegant (especially when "ITV News Tyne Tees & Border" was a thing!), but there's nothing as messy as the BBC's red box logo being at the bottom and yet you're not supposed to read/perceive it as being part of the actual programme name.
I could charm the vultures off a corpse.
