At the time, I lived in the Border region, and I remember the Border logo that sits in the V, but I don't remember the ITV logo.
I was only little, though, so I wouldn't trust my memory too much. I'm mainly remembering it from Border Birthdays.
In the early 90s, Border actually made their own idents using versions of the 1989 ITV logo as seen in promos - and used them alongside the original 1989 ident.
The logo itself is fairly timeless and wasn't bettered by them until the current one was introduced. It wasn't that flexible, though the best adaptation of it was one Christmas when the triangle in the V was turned upside down and turned into a Christmas tree.
When Thames unveiled its second triangular logo in around 1991, they incorporated triangles into other elements of presentation and local news titles and sets. In hindsight, ITV could have made more use of the triangular ‘V’ in a similar way in 1989 - if the technology was there, promos could have used the V in a similar way to the “dot” in 2013, with the filmed content appearing and disappearing into the V, or the V showing an element of the programme being promoted.
Actually Scottish got rid of invision during the summer 1998 and created a new black idents to help fill the gap, ie it operated along side the 89 ident.
Did Grampian discontinue or reduce IVC when their 1998 logo was introduced? I remember seeing the saltaire quite a bit when I visited the Highlands in the late 90s.
