Im sorry. Im not being funny or anything.... What is the point of leaving pretty much everything the same and but there is just a change to the font? Most viewers are hardly going to notice.
You either give a show a new look to freshen it up, or you don't.
Very few people will notice a change in font, so whatever money they've spent, I can't really see the point.
So you don't think an organisation should use the same typeface throughout? What about consistent branding of any kind? Should they just have different BBC logos for each channel, or even programme? Why not different music for each BBC News bulletin?
Of course not. There is such a cluttered marketplace nowadays that a strong and consistent brand is essential - and more and more a key part of that is the typeface.
BBC Reith is, in my view, a beautiful typeface and it makes total sense for the BBC to use it across all its services.
