TV Ratings: Decent ‘Undateable’ start helps NBC Tuesday, ‘iZombie’ is OK too

Fast National ratings for Tuesday, March 17, 2015.

While it was “The Voice” and “Chicago Fire” that really paved the way for NBC's Tuesday wins, the “Undateable”/”One Big Happy” comedy block got off to an OK start and certainly didn't prevent those Tuesday wins.

“Undateable” and “One Big Happy” took advantage of a 9 p.m. hour in which “NCIS: New Orleans” and “New Girl” were in repeats, but still came in below the fall premieres for “Marry Me” and “About a Boy,” though they were in line with the second week for those comedies, so we'll see how the numbers look next Tuesday.

Without a new “NCIS: New Orleans,” ABC's “Marvel's Agents of S.H.I.E.L.D.” ticked up week-to-week.

Tuesday's other big premiere was The CW's “iZombie,” which had a low-ish “Flash” return as its lead-in, but debuted to numbers comparable to what “Supernatural” had been doing in the time period. Helped by all of the competing repeats, The CW spent a rare night in second place among young viewers.

On to the Tuesday ratings…

Among adults 18-49, NBC averaged a 2.2 rating for Tuesday night, doubling up second place The CW's 1.1 rating in the key demographic. ABC, NBC and FOX all averaged a 1.0 key demo rating for the night.
