Controversial opinion time (and one I doubt Mumoss will like either), but I always thought the 1991 BBC1 globe seemed dated even at the time it was introduced, and certainly was well past it by 1997, with them having to rely entirely on trailers (and sometimes stings) to bring much to the brand for most of the 90s.
I think it's the font of the number "1" that does it. If they'd changed the font to the same as that of BBC2's "2", then it might have looked considerably more modern but still maintaining a tradition.
They tried it with a modern 1 to begin with and it looked awful. I think the trouble is a 1 isn't that interesting a shape so it needed to be as stylised as it was, and it worked well in most guises at the time.
Did the surrounding presentation based around the 1 appear from launch or was that introduced a couple of years down the line.
I do think BBC2 shows that if done well there is still a place for classic style idents and as someone said on Twitter "Oneness" is actually essentially a return to quiet idents.
Not sure if they're still up in the gallery but always felt the globe idents by pip2 were the best idents BBC1 never had.
Stay Local. Stay Safe. Stay Alive.
