That whole look of a bit of a map, which often was really identifiable as anywhere in particular, flying around a bit, was bloody awful.
IIRC, the shapes for the English Regions each "rounded up" and/or "rounded down" to whole counties, so weren't a totally accurate representation of the scope of each region. This was balanced by the selection of "destinations" giving a more accurate indication.
For example, the region shape on Points West included
all
of Somerset (right up to the Devon border within Exmoor), but I'm sure it didn't feature any place names that would be firmly Spotlight-only territory.
Conversely, the South Today map titles (both in their original form, and when they were revised due to the break-up of Newsroom South East) did not include any part of Wiltshire or Surrey in the shape, and yet mentioned e.g. Salisbury and Crawley. In their latter form, they no longer included any part of the East Sussex county in the shape but continued to list Brighton & Hove.
