ABC's Kingdom Hospital has claimed another victim: Susan Lyne has stepped down as the network's entertainment president. The move comes two weeks after Lloyd Braun exited his post as network chairman, four weeks after Stephen King's Kingdom Hospital was put on life support, six months after the arrival of It's All Relative and more than a year since Are You Hot? crashed and burned. So, who's minding the store now? Touchstone Television president Stephen McPherson, the dude responsible for such shows as Scrubs and Alias. I like him already.
