According to a breaking story at
DRUDGE REPORT, "FOX TV topper Sandy Grushow relieved of duties, DRUDGE has learned, Murdoch concerned with direction of net, ratings..."
Grushow was responsible for not green-lighting Tom DeSanto's "Battlestar Galactica" show, instead opting for "Firefly" which was ill-placed within the FOX television lineup (which faced poor scheduling and marketing which ultimately doomed that show).
