NBC’s new latenight combo of Jimmy Fallon and Seth Meyers continues to shine in the ratings well into their second month together.

According to Nielsen estimates for March 24-28, “The Tonight Show Starring Jimmy Fallon” averaged a 1.33 rating in adults 18-49 last week (roughly 1.7 million in this age group), beating the combined 18-49 scores of ABC’s “Jimmy Kimmel Live” (0.65) and CBS’ “Late Show With David Letterman” (three-night average of 0.53 due to college basketball overruns on Thursday and Friday).

And in total viewers, its 4.306 million kept it comfortably on top of both Letterman (2.856 million) and Kimmel (2.694 million).

Despite being this deep into its run, “Tonight” under Fallon is delivering considerable viewers in key demos than it did at this time a year ago with Jay Leno. Its 1.33 rating for week 6, which was just lower than slightly lower than the 1.35 for Week 5, is 75% bigger than the comparable week of 2013, and its 1.00 rating in adults 18-34 is more than double last year’s 0.46. In total viewers, it was up 20% from last year.

On Wednesday of the current week, ABC’s “Jimmy Kimmel Live” scored stronger than usual ratings as President Clinton visited for the first time. It matched a six-month high in household overnights (2.4/6) and beat NBC’s “Tonight” in New York and Los Angeles in young adults, but the Peacock program still won the night across the country.

At 12:35 a.m., NBC’s “Late Night With Seth Meyers” hit three-week highs last week, with its 0.70 rating in adults 18-49 and 1.995 million total viewers up vs. the prior week by 4% and 8% respectively. In 18-49, it outdelivered CBS’ “Late Late Show With Craig Ferguson” by 79% (0.70 vs. 0.39) and ABC’s “Nightline” by 95% for their common half-hour (0.80 vs. 0.41).

Meyers outperformed the comparable year-ago “Late Night” hour with Fallon as host by 43% in adults 18-49 (0.70 vs. 0.49) and 20% in total viewers (1.995 million vs. 1.663 million).

Perhaps most impressive is that Meyers last week drew more young adults than the Letterman and Kimmel shows airing one hour earlier.
