SURVIVOR APRIL 16On a night of a lot of repeats on the networks, it was primetime battle between veteran reality shows last night. And though Survivor (2.2/8) dipped 8% from last week, the CBS show again was the reality TV victor. With 9.28 million viewers watching between 8-9 PM, the 28-season-strong series topped the 8.25 million total viewers and 1.9 rating among adults 18-49 American Idol had in their common hour. This is the fourth week in a row Survivor has beaten Idol in viewership and the sixth consecutive week the CBS show has come out on top in the demo in the 8 PM slot. Still, it wasn’t a stain-free victory march — as the numbers stand now, Survivor has hit a series low. That could change when the final numbers come in later today. Otherwise, CBS was all encores with Criminal Minds (1.4/4) and CSI (1.2/4).

With visits from former X Factor judge Demi Lovato and Terry Bradshaw among others, last night’s Idol was almost all performance with the remaining seven contestants choosing the tunes for each other to sing. With a 1.9/6 rating in adults 18-49 and little bit of Radiohead, some Ed Sheeran and a duet of the Stones’ Gimme Shelter among the songs, Wednesday’s two-hour live show slipped 5% from last week. With that close a margin and the flexibility Idol has shown repeatedly in the final numbers, an adjustment upward is probably in the offing. Overall, Fox won the night in the demo with a 1.9/6 rating and among total viewers with 8.38 million.

Back with its first original in two weeks, the CW’s Arrow (0.7/2) hit a target it probably wished to miss. The DC Comics-based superhero series was down 13% from its April 2 episode to tie a series low. Arrow tends to have a certain resilience in the final numbers so an adjustment out of that low would not be unexpected. On the other hand, newbie The 100 (0.6/2) probably like their result just the way it is. After hitting a low last week, the post-apocalyptic drama leaped up 20% last night from its April 9 airing.

NBC was all encores last night as was ABC, except a new Mixology (1.2/3). Like last week, the floundering freshman was alone in the network’s lineup but was spared additional misery as it stayed even with last week’s low.
