The ratings for the inaugural episode...drew a respectable 226,000 viewers
Online, and particularly YouTube, where “SNL” skits tend to have their most successful half-life, Fey’s opening monologue attracted over 1.6 million views in less than 48 hours, followed by the Keir Starmer cold open with 1 million views.
It's interesting because those YouTube views are roughly in line with the viewership of SNL in the US (on YouTube).
I wonder if the same people are watching both series.
