In Nielsen’s metered-market overnights, “Tonight” averaged a 4.5 household rating/12 share, followed in the 11:35 p.m. timeslot by CBS’ “Late Show With David Letterman” (2.2/6) and ABC’s “Jimmy Kimmel Live” (2.1/6). While the 4.5 represents a low for “Tonight” under Fallon (it was above a 5 every night during the Olympics), it’s 55% above the program’s non-Olympics average this season (2.9).

“Fast official” Nielsen estimates, including overall viewer estimates, were expected later Tuesday morning.

In the 25 markets with Local People Meters, “Tonight Show” averaged a 2.1/10, roughly doubling the combined tallies of “Kimmel” (0.6/3) and “Late Show” (0.5/2). This is the best “Tonight” score for a non-Olympics Monday since Conan O’Brien’s premiere in June 2009 (3.9).

For ABC, “Jimmy Kimmel Live” was up over the previous Monday to match its top score since Feb. 3. CBS’ “Late Show” was also up a bit from last Monday, which was Fallon’s debut on “Tonight.”

Fallon premiered to a 2.3 overnight household rating on “Late Night” in its 2009 debut.

The 2.6 topped the combined ratings in the timeslot of ABC’s “Nightline” (1.4/5 for the first half-hour of the time period) and CBS’ “Late Late Show With Craig Ferguson” (1.0/4).

In the 25 markets with Local People Meters, “Late Night With Seth Meyers” averaged a 1.2 rating/8 share in adults 18-49, also the best for “Late Night” since the O’Brien premiere on “Tonight” in 2009. “Nightline” did a 0.4/2 in the demo from 12:35-1:05 a.m., and “Late Late Show” pulled a 0.2/2 from 12:35-1:35 a.m.
