The "West of England" telly region isn't very big, right?
And, given the amount of overlaps with other regions (e.g. Southwest/South/WMids), and the fact that - allegedly - a lot of viewers in those overlap areas may be more likely to prefer the "not West" option, the area that
definately recieves nothing but "West" telly
is really small indeed.
So much so, that... is there any point in a "West of England" telly region even existing? Couldn't one or more neighbouring region(s) have its/their official patch extended?
Politically, isn't the "West" actually part of the wider "South West"? So couldn't the area just have a "North sub-region" variant of BBC Spotlight/ITV Westcountry? Perhaps Calendar-style (i.e. main programme only, all short bulletins pan-regional from Plymouth)? Or something?
It doesn't seem to really warrant being a region in its own right, IMHO.
Also, it's so far south, that it's not actually the "
West
" of England at all!

If Wales were a region of England, rather than a different nation, then it would have the best claim to the "West of England" name, being as it is, er, on the exact opposite side of "The Midlands" to where "East Anglia" is!
So, as Wales exists, England doesn't naturally have a "West" (unless we slimmed down our definition of "Midlands", in which case Shropshire/Herefordshire etc would have the best claim to the "West of England" description).
