The veteran and the rookie led the entertainment pack last night as Fox’s The Simpsons, the longest-running primetime scripted series on air, tied newcomer Once Upon A Time as the highest-rated non-sports program with a 3.7/9 in adults 18-49. For ABC’s Once Upon A Time, this is a modest 5% dip from last week; The Simpsons too was down slightly from last week’s Treehouse of Horror (8%).
