TV Ratings: 'Undateable' Live Run Starts Soft, 'Dr. Ken' Holds in Week 2

The NBC comedy shifts to Friday with an hour-long premiere, averaging a 0.8 rating in the key demo.

NBC's stretch of all-live Undateable episodes kicked off Friday night with the comedy's third season premiere.

The one-hour outing, which had to be a bit of an endurance challenge for its cast, averaged a 0.8 rating among adults 18-49 and 2.6 million viewers. Soft, for sure, that's down from the recent season premiere — though there's really no comparison to be made, as that episode got a lead-in from an original episode of The Voice.

Stacked against the night's other comedies, with which Undateable was in direct competition, the series trailed. Last Man Standing, averaged a steady 1.3 rating in the key demo. And Dr. Ken, which managed an impressive 2.0 rating among adults 18-49 in its first live-plus-three day showing, was down only two-tenths of a point from last week's live-plus-same debut a 1.3 rating in the demo as well.

Elsewhere on ABC, which topped the night in the key demo, Shark Tank (1.5 adults) and 20/20 (1.0 adults), while CBS had new episodes of The Amazing Race (1.1 adults), Hawaii Five-0 (1.1 adults) and Blue Bloods (1.2 adults).

The CW saw Reign move to Fridays, averaging a 0.3 rating among adults 18-49, before a new America's Next Top Model (0.3 adults).

Dateline, which had a two-hour episode on NBC, averaged a 0.9 rating and 4.5 million viewers — slightly better than Undateable.
