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

· A Feb. 18 encore of "Saturday Night Live," with host Dave Chappelle and musical guest A Tribe Called Quest, has averaged a 3.6 share, 9 share in households in Nielsen's 56 metered markets and a 1.3/7 in 18-49 in the 25 markets with local people meters.

· Excluding the Jan. 7 rebroadcast, which benefited from an NFL Playoff overrun, it's the highest-rated "Saturday Night Live" encore in two years in metered-market households (since Feb. 14, 2015, with an encore of the "SNL" series premiere with host George Carlin and musical guests Janis Ian and Billy Preston, 3.8).

· Versus what the show averaged last year with February encores, the Feb. 18 "SNL" is up +20% in metered-market households (3.6 vs. 3.0) and up +8% in 18-49 in the local people meters (1.3 vs. 1.2).

· Last night's "Saturday Night Live" encore was the #1 telecast of the night on the broadcast networks in metered-market households and 18-49 in the local people meters, outrating every Saturday primetime telecast on those nets in both categories.
