There would be few if any commercial interruptions, there would be a ticker-tape along the bottom of the screen updating the facts as they came in, and there would be no dramatic soundtrack accompanying the news broadcast. For viewers to experience a television programme as if it were a live television news broadcast, they would have to suspend all of this knowledge about these different formats, something that is very difficult to do.
