In late-night metered market ratings (via NBC's press release):

· A March 21 encore edition of "Saturday Night Live," with host JJ Watt and musical guest Luke Combs, has averaged a 2.9 rating in "live plus same day" household results from 44 local markets metered by Nielsen Media Research and a 0.9 rating in adults 18-49 in the 25 markets with local people meters.

· Last night's "Saturday Night Live" is tied as the #2 highest-rated "SNL" encore in metered-market households among the 11 aired in this timeslot since Nielsen revised its metered-market methodology on Oct. 5, 2019, trailing over that span only the Jan. 11 rebroadcast (3.1 in metered-market households with host and musical guest Harry Styles). The Feb. 15 "SNL" encore (with host Eddie Murphy and musical guest Lizzo) also scored a 2.9 in metered-market households.

· Versus primetime programming on the Big 4 networks last night, the "SNL" rebroadcast is the #1 show of the night in metered-market households and in 18-49 in the local people meters.

· Note that current metered-market results are not compatible with data issued before Oct. 5 due to changes in Nielsen methodology.
