Sitting in the NPR broadcast booth at Pepsi arena, looking down at the podium, you are struck at how bright, crisp, and arresting the speaker's dais is. Reports are that the major news networks poured millions into making the DNC widescreen-plasma worthy. The money paid off. Even to the naked eye, high above the convention floor, this is the first HD convention. Of course, Barack Obama won't accept the nomination here. He'll give his major speech at Invesco Field at Mile High. And the set there, I hear, isn't quite as widescreen-plasma worthy.
