Tuesday Results (please note corrected "Voice" results):

For the first time in eight years, NBC has won the opening two Tuesdays of the season among the Big 4 networks in adults 18-49. Last night, NBC swept all six half-hours among those networks with the #1 show of the night, "The Voice," teamed with "Chicago Fire," which is currently reporting series-record ratings.

NBC also swept the Monday half-hours among ABC, CBS, NBC and Fox in 18-49 and has now won 12 of 12 half-hour among those networks so far this week.

· From 8-10:01 p.m. ET, "The Voice" (4.4 rating, 13 share in adults 18-49, 14.2 million viewers overall from 8-10:01 p.m. ET) is #1 for the two-hour time period in adults 18-49, and virtually all other key demographics and is the #1 show of the night in 18-49 and other measures. "The Voice" is running within 4% of last week's fast-affiliate rating in 18-49 (4.4 vs. 4.6) and up slightly in total viewers (14.204 million vs. 14.137 million). Official nationals for last Tuesday were 4.7/13 and 14.351 million.

· From its first half-hour to its fourth, "The Voice" grew 1.8 rating points or 53% in 18-49 rating (to a 5.2 from a 3.4) and up 42% or nearly 4.9 million persons in total viewers (16.5 million vs. 11.7 million).

· "Chicago Fire" (2.8/8 in 18-49, 9.000 million viewers from 10:01-11 p.m. ET) once again dominated the 10 p.m. ET slot among ABC, CBS and NBC in 18-49, with a 40% margin of victory over CBS's #2 "Person of Interest" (2.8 vs. 2.0).

The 2.8 rating is NBC's top 18-49 result in this time period with in-season regular programming since May 24, 2011 ("The Voice").
