Two of NBC's new shows are the latest casualties of the Fall TV season. Welcome to the Family, the comedy starring Mike O'Malley, and Ironside, Blair Underwood's police procedural, have been canceled. Neither show was doing well in the ratings department, so this doesn't come as a huge surprise. Dateline will take over Ironside's primetime spot and Parks and Recreation reruns will fill the void left by Welcome to the Family. Better luck next time, guys.
