I am in total sympathy with the OP. It is so frustrating, and not limited to ITV. I first noticed this over 30 years ago with US programmes. They must be much faster readers than we are. Whatever happened to the good old slow-scrolling credits? Incidentally, if you ever get a chance to see again Airplane, or other Leslie Nielson films, watch the credits with close attention. There are probably more jokes there than in the films themselves.
