Carly Fiorina Helps NBC’s ‘Tonight Show’ Dominate Late-Night Ratings Monday

NBC’s “The Tonight Show Starring Jimmy Fallon” opened the 2015-16 season a big winner last night, as guests Carly Fiorina and Ryan Reynolds lifted the program to its top Monday overnight score in 18 months. The show also doubled the demo delivery of CBS’ “Late Show With Stephen Colbert” and tripled the score of ABC’s “Jimmy Kimmel Live.”

In Nielsen’s metered markets, “Tonight” averaged a 3.2 household rating/8 share, followed by “Late Show” (2.5/7) and “Jimmy Kimmel” (1.9/5). The NBC program likely was aided by the network’s winning primetime lineup, but it also got a bump from the first late-night appearance of Fiorina, coming on the heels of a strong performance in the most recent GOP primary debate that vaulted her in the most recent polls.

Colbert’s guests included another of the Republican presidential hopefuls, Ted Cruz, while Kimmel’s guests included Bill O’Reilly of Fox News Channel and Kermit and Miss Piggy of ABC’s new comedy “The Muppets.”

Last night’s 3.2 rating for “Tonight” is below the 3.6 overnight rating generated by Donald Trump’s visit on Sept. 11, but it matches the top Monday score for “Tonight” since March 2014. Both “Late Show” and “Kimmel” were in line with their averages of last week.

In the 25 markets with Local People Meters, “Tonight Show” averaged a 1.2 rating, jumping 19% above its 2014-15 average prior to Colbert’s debut (3.2 vs. 2.7). It beat the combined scores of CBS’ “Late Show” (0.6) and ABC’s “Kimmel” (0.4).

After Colbert’s premiere-night ratings triumph on Sept. 8, NBC’s “Tonight Show” has been the late-night leader in adults 18-49 on each of the last nine nights.

From 12:35 to 1:35 a.m., NBC’s “Late Night With Seth Meyers” notched its highest Monday overnight household rating (1.4) since early March, easily topping CBS’ “Late Late Show with James Corden” (1.0) and also beating the half-hour average of ABC’s “Nightline” (1.2). In 18-49, “Late Night” (0.5) more than doubled “Late, Late Show” (0.2) and also beat “Nightline” (0.3).
