I don't have the comparisons to last season's comparable date's ratings, but SNL was down a tenth of a HH ratings point vs. last Saturday.
Directly from NBC:
In late-night metered-market households Saturday night:
- SATURDAY NIGHT LIVE (4.6/11 in metered-market households), hosted by Drew Barrymore and featuring musical guest Regina Spektor, dominated its time period.
- SATURDAY NIGHT LIVE delivered the #1 non-sports rating of the night in the metered markets, topping all primetime entertainment telecasts on all the major networks. In fact, SNL outscored every Saturday primetime non-sports telecast on every major network over the past four months (since June 6).
