Tuesday Results:

NBC is #1 Tuesday night among ABC, CBS, NBC and Fox in adults 18-49 and total viewers and #1 or tied for #1 among those nets in all other key measures, led by the #1 show of the night in 18-49, total viewers and all other key categories, "America's Got Talent."

· From 9-11 p.m. ET, "America's Got Talent" (2.6/8 in 18-49, 10.0 million viewers overall) is the #1 telecast of the night on ABC, CBS, NBC and Fox in 18-49, total viewers and all other key categories, with a margin of 63% versus the #2 show in 18-49 (2.6 vs. 1.6 for Fox's "So You Think You Can Dance" from 8-10 p.m.). "Talent" is #1 in the slot among ABC, CBS, NBC and Fox in every key ratings category

· "Talent" built by 23% from its first half-hour to its fourth in adults 18-49 (to a 2.7 rating from a 2.2). In total viewers, "Talent" grew by 20% or more than 1.7 million persons (10.6 million vs. 8.8 million). For its second hour from 10-11 p.m., "Talent" topped the encore-drama competition on ABC and CBS combined in every key category -- adults, men and women 18-34, 18-49 and 25-54, plus total viewers.

· In the 10:30 lead-in to local news, "Talent" delivered a 183% margin of victory among ABC, CBS and NBC in the key news demo of adults 25-54 (with a 3.4 rating vs. a 1.2 for CBS's second-place "Person of Interest" encore).
