GMB will probably gain some viewers today thanks to this very poorly implemented "revamp" of Breakfast.
I doubt the number will be that high, but I'm sure at least a few will jump ship.
EDIT: Looking on Twitter, reaction is minimal. As I said, likely to have little effect on ratings.
Does the general viewer really think "I'm no longer watching BBC Breakfast because they don't have a decent title sequence / inconsistent presentation?". I know it's disappointing to many on here (myself included) but I'd put money on the general, sizeable audience for BBC Breakfast not giving two hoots about it and continuing to watch as they did.
Not that there's much to give two hoots about this morning...
