Paced by Sunday Night Football, The Voice and freshman drama Blindspot — which is tied as the top new series this season — NBC won the November primetime Nielsen sweep in the demo, marking its fourth consecutive win.

Blindspot (NBC)With three nights left to count, NBC is delivering a 21% margin of victory in 18-49, which is the biggest November ratings edge in 19 years. The four wins in a row represent NBC’s longest November streak since the network took four straight from 2000-03.

CBS is on track to be the most-watched network of the sweep, with an average of 9.57 million to NBC’s 8.13 million, which put it in second place.

According to Live+Same Day results through 25 of the month’s 28 nights, NBC ranks No. 1 among the Big 4 networks in every key demo, including adults, men and women 18-34, 18-49 and 25-54.

NBC did so by ranking No. 1 on The Voice nights of Mondays, Tuesdays and on Sundays with football. If its numbers in the demo hold when final stats come in, it would mark the biggest percentage win for any network in a November sweep in 19 years, since NBC in 1996. Last year’s NBC margin for the November derby’s full 28 nights was 15%.

NBC has retained 99% in total viewers (8.13 million vs. 8.24 million) with three nights yet to count.
