No joke: CBS’ The Late Show with Stephen Colbert kicked off the week of April 1, 2024 with a Nielsen ratings win, beating the late night competition on Monday both in total viewers and among Adults 18-49.

CBS’ 11:35 p.m. late-night offering averaged 2,217,000 total viewers and 309,000 P18-49 viewers on Monday, April 1, per Nielsen live-plus-same-day data. In addition to being No. 1 in both measurements, The Late Show gained +4% in total viewers and a solid +38% in P18-49 viewers from the previous Monday episode (March 25, 2024).

Matt Damon, and Hannah Waddingham were Colbert’s Late Show guests this past Monday, April 1.

After a week off, ABC’s Jimmy Kimmel Live! returned on Monday with a new episode, which averaged 1,404 total viewers and 195,000 P18-49 viewers. That’s No. 2 at 11:35 p.m. in both key audience measurements.

Billy Crystal, J.B. Smoove, and SiR were Kimmel’s Monday, April 1, 2024 guests.

Despite a guest appearance from Hillary Clinton, NBC’s The Tonight Show Starring Jimmy Fallon finished third in P18-49 viewers (192,000), and third in total viewers (1,129,000) this past Monday. The program shed -12% in total viewers and -10% in P18-49 viewers from the prior Monday’s original episode.

In addition to the former Sec. of State and 2016 presidential candidate, other April 1 Tonight Show guests included Jonathan Groff, and Sasha Alex Sloan.

NBC’s Late Night with Seth Meyers and CBS’ After Midnight split first place at 12:37 a.m., and each delivered week-to-week gains.

Late Night averaged 787,000 total viewers but only 117,000 P18-49 viewers this past Monday, up +7% and up +8%, respectively from the prior Monday episode. After Midnight averaged 690,000 total viewers and 153,000 P18-49 viewers this past Monday. That’s up +10% in total viewers and a solid +46% in P18-49 viewers from the prior Monday episode.

Jeremy Strong, Amber Ruffin, and Fred Armisen were Meyers’ guests on Monday’s Late Night. Jourdain Fisher, Arden Myrin, and Zach Zimmerman appeared on Taylor Tomlinson’s After Midnight.

ABC News’ half-hour offering Nightline aired an original episode this past Monday which averaged 735,000 total viewers and 108,000 P18-49 viewers at 12:37 a.m. That’s -19% in total viewers and -16% in P18-49 viewers from the previous Monday episode.

Jon Stewart returned to The Daily Show on Monday, but viewers didn’t necessarily travel with him. Featuring Federal Trade Commission chair Lina Khan as guest, the April 1, 2024 Daily Show drew the smallest Stewart Monday audience since his part-time return to the anchor desk this past February. The April 1 episode averaged just 693,000 total viewers and 165,000 P18-49 viewers, per live-plus-same-day data. That’s a -18% decline in total viewers, but only a -1% decline in P18-49 demo viewers relative to the most-recent Monday Daily Show original. Despite the drop-off, Stewart Mondays continue to haul in a far larger audience than what The Daily Show averages when its correspondents are at the desk.
