I have our marketing people send everything to the graphics department to be redrawn into vector artwork in Illustrator so I avoid explaining everything to the same guy 38 times...this is the same guy that always wants frame grabs of our stuff to use in print publications - and for years we've been trying to explain why that's a bad idea - you basically get a photo that's 720x486 at 72dpi. So while you are correct about the 72dpdi - it's a decent way of explaining to non-tv-pros how much detail NTSC SD television has and why 13" tv's look so much better than the big screens...of course with all the changes in televsion these days, this simplified explanation will change.
