If the D.O.G. burn into screen on every channel that has a DOG
then we will end up with a lot of DOGs over each other. Unreadable
So they will then need to move them from the left to the right of the screen (as with Channel4 +1)
Then when the top left and right of the screen is ruined/unreadable they will move them to the bottom corners (as with USA TV)
And then stick them in the center of the screen.
Perhaps they should have a DOG that moves from corner to corner and flashes between black and white.
That would fix the screen burning problem.
BBC1 HD and ITV1 HD has a DOG, but BBC1 SD and ITV1 SD is dogless.
