Despite getting little support from NBC’s primetime lineup, “Tonight Show With Jay Leno” stayed on top in the latenight ratings race during the February sweep, edging out CBS’ “Late Show with David Letterman” and also besting timeslot newcomer “Jimmy Kimmel Live” on ABC.
According to Nielsen estimates for the Jan. 31-Feb. 27 sweep period, Leno’s show won the 11:35 p.m. hour in adults 18-49 with an average audience in the demo of 1.003 million to 929,000 for Letterman and 898,000 for Kimmel. The advantage for “Tonight” in the demo (8%) was up from a 2% margin in February 2012 and up from a 6% advantage last November.
In total viewers, Leno’s 3.51 million edged out Letterman’s 3.29 and was well ahead of Kimmel’s 2.53 million. In his first sweep airing at the earlier time of 11:35 p.m., Kimmel logged its most-watched sweeps month to date, topping the 2.12 million it drew last November when it started at midnight.
The victory for Leno is more impressive considering the lack of primetime circulation for NBC during the month, as the net’s performance in the 10:30 p.m. half-hour leading into the late local news lagged well behind that of CBS and ABC.
In their common half-hour, Fallon also beat ABC’s “Nightline” — by 31% in adults 18-49 (683,000 to 520,000), by 13% in adults 25-54 (795,000 to 701,000) and by 17% in total viewers (1.81 million to 1.55 million). For its full duration (12:35-1:05 a.m.), “Nightline” averaged 527,000 adults 18-49, 716,000 adults 25-54 and 1.605 million viewers overall — well down, as expected, from when it aired from 11:35 p.m. to midnight.
