The return of Elliot Stabler to New York was good for NBC on Thursday.

The 10 p.m. debut of “Law & Order: Organized Crime” delivered a 1.6 rating in the adults 18-49 demographic and an average of 7.9 million viewers in Nielsen’s live same-day preliminary ratings. The series marks the return of Christopher Meloni to the “Law & Order” franchise in the detective character he played for 12 seasons on “Law & Order: SVU.”

“Organized Crime” launched as a crossover event episode paired with “SVU” at 9 p.m., which averaged 1.7 rating in adults 18-49 and 8 million viewers. The crossover storyline that reintroduced the Stabler character to viewers nearly doubled the “SVU’s” average ratings for originals this season, which have come in at 0.6 in the demo and 3.7 million viewers.

In the adults 25-54 demo, “SVU” climbed to 2.1 rating while “Organized Crime” hit held at a 2.0. In the adults 35-49 measure, “SVU” delivered a 2.4 to “Organized Crime’s” 2.3.

Elsewhere in primetime, CBS had a more modest start for comedy “The United States of Al,” which grabbed 5.3 million viewers and and 0.6 in adults 18-49 in its 8:30 p.m. debut behind “Young Sheldon,” which pulled in 6.4 million and 0.7 in the demo. CBS predicts “Al” will increase to 6.2 million in L7 ratings when seven days of time-shifted viewing is factored in.

The “Law & Order” double-header took a toll on ABC’s “Grey’s Anatomy,” despite a heavily promoted episode featuring the return of long-gone characters played by Chyler Leigh and Eric Dane. “Grey’s” averaged 4.6 million viewers and 0.9 in the demo. ABC’s 8 p.m. drama “Station 19” opened the night for the network with 4.8 million viewers and 0.8 in 18-49.

Overall, NBC handily won the night with an average of 6.6 million viewers and 1.3 in adults 18-49.
