One of the big four TV broadcast networks had some November sweeps ratings news to crow about today. ABC sent out a press release announcing that it won all four Thursdays in November for the first time in “at least 23 years.”

The results are in the key demo of adults 18-49, based on Nielsen Live + Same Day ratings. ABC accomplished the feat for the first time since at least November 1991, the earliest sweeps period in the Nielsen database.

The Alphabet Network is thriving on Thursdays — traditionally a key night for broadcasters for advertising revenues — with its “all-Shonda Rhimes” lineup of “Scandal,” “Grey’s Anatomy” and “How to Get Away With Murder.” In Thursday results for this week, “Scandal” and “Murder” both delivered preliminary 3.1 average ratings in 18-49 while “Grey’s” pulled a 2.4. ABC easily won the night in the metric with an average rating of 2.9, ahead of CBS (2.1 average), Univision (2.0), NBC (1.6), Fox (1.0) and CW (0.6).

ABC also won the night in total viewers, averaging 9.37 million to lead CBS (8.90 million), Univision (4.49 million), NBC (4.42 million), Fox (4.22 million) and CW (1.41 million).

The network noted that “Murder” hit a six-week high in 18-49 and topped the combined drama competition from NBC (“Parenthood,” 1.5 average) and CBS (“Elementary,” 1.0) in the 10 p.m. hour.
