On the morning shows today, ABC led with Terri Schiavo, and CBS made it number 3 (after steroids and the David Letterman child-napping threat.) Both gave it serious news time. But NBC did only a couple of quick anchor reads. NBC beat the stuffing out of the steroids issue this morning instead. They also had more time for an interviews promoting the NBC drama “Crossing Jordan” and the Broadway satire “Spamalot” than they did for a woman on the verge of being executed.
