Fortune: Of the four major networks, Comcast’s NBC has the most new shows scheduled this fall — six, compared with five each from ABC, CBS and Fox. Still, NBC has scaled back its new programs. After running out a disappointing lineup of new comedies last fall, the network canceled eight of its 11 new shows from last year and loaded up on dramas for this fall, with four of its six new shows in that category. While NBC has had plenty of recent ratings success, the network has had difficulty developing hit new shows over the past few years.
