scandalRemember when Thursday was the biggest night on television with the top networks drawing 18-49 ratings in the double digits? That was all a distant memory last night. With CBS’ regular lineup led by The Big Bang Theory benched for NCAA basketball, the highest-rated broadcast network Thursday night was ABC with a 2.0 average in 18-49. Only two series — ABC dramas Grey’s Anatomy (2.4, up 0.1 from last week) and Scandal (2.9, +0.2) — crossed the 2.0 demo rating threshold.

Among those that didn’t was Fox’s American Idol (1.9), its first time ever below 2.0. The singing competition continued its downward spiral, off 14% from last Thursday and this Wednesday’s series low to a new series low. Its lead-in, Hell’s Kitchen (1.7), was down 11% in its second week.

NBC’s Community (1.1) saw a 0.1 week-to-week pump, while Parks And Recreation (1.2) and Parenthood (1.2) were flat. Good news for Hollywood Game Night: While it has been soft in its regular-season run, the game show showcased its good repeatability last night with a 0.9 rating for a rerun — off just by a tenth from last Thursday’s original. Elsewhere last night, Once Upon A Time In Wonderland (0.8) was even, while CBS’ opening night of NCAA hoops coverage logged a 1.1 in the non-time-zone-adjusted fast nationals, down 31% from the comparable rating last year. CW’s The Vampire Diaries (1.0) was even with its most recent new episode on March 6. Reign jumped 40% to a 0.7.
