TV Ratings: 'iZombie' Gets a Good Start, 'Undateable' Jumps With New Lead-in

The NBC comedy jumps with new neighbor 'The Voice,' while 'One Big Happy' has a solid premiere.

The CW launched its latest series iZombie on Tuesday night. With a lead-in from freshman hit The Flash, it pulled a solid 0.9 rating among adults 18-49 and 2.3 million viewers. That's in line with how The 100 premiered last midseason. Meanwhile, its lead-in was a bit humbled with The Flash off three-tenths of a point from its last original at a 1.2 among adults.

The Voice pulled a 3.1 rating in the same demo in its one-hour outing, down 9 percent from the same period last week. Undateable (1.9 adults) got off to a promising start for its second season, rising 46 percent with the new Voice intro. One Big Happy debuted with a 1.6 rating in the key demo, while Chicago Fire (1.6 adults) dropped half of a point.

With many repeats on the rest of the broadcast networks, the night's only new outings, ABC's Agents of SHIELD (1.6 adults) and Fox's Hell's Kitchen (1.3 adults) and The Mindy Project (0.9 adults), all held steady.
