AI April 9Last night on American Idol (2.0/6) the ’80s were truly back in force. The two-hour live performance show saw the Top 8 belt out tunes from Blondie, Journey, Joan Jett, and Cyndi Lauper among others, some advice from Season 7 winner David Cook, a new hairdo from judge Keith Urban, plus an impromptu Madonna tune from Harry Connick Jr. It also saw the long-running reality competition series remain pretty steady with last week in adults 18-49 with a 5% dip and even with its total viewership of 8.8 million on April 2.

Idol again came up short against Survivor (2.4/8) in their common hour. Airing between 8-9 PM and the highest-rated show of the night, the veteran CBS competition series bopped up 4% from last week in the key demo. The Fox show drew a 1.9 among the 18-49s in the one-hour overlap. That’s the worst Idol has done against Survivor in adults 18-survivor april 949. The CBS show topped the Fox show for the first time ever in the common hour on March 12. The victory lap continued March 19 and saw Survivor beating Idol in total viewers in the 8 PM slot for the first time. On March 26, the one-hour Survivor bested the 2-hour Idol in total viewers overall.

CBS won the night with a 2.1/7 rating and 9.48 million viewers overall. But the rest of the network’s Wednesday did not enjoy the rise Survivor saw. Criminal Minds (2.3/7) was the night’s most-watched show with 9.81 million viewers, but it was down 12% from last week, and CSI (1.7/5) slipped 6% from its April 2 episode. Looking at the results of Idol in the 9 PM common hour against Criminal Minds, the Fox show garnered a 2.1 among adults 18-49 and 9.04 million total viewers.

The only original on ABC last night was Mixology (1.1/3 which, without any new shows as lead-in, took a free-fall of 31% compared with last week. That’s a new low for the struggling freshman. The CW’s only original show was The 100 (0.5/2). Without a new Arrow as a lead-in, the new drama was down a tenth to also hit a low.

It was a good collar for Law & Order: SVU (2.0/6) on NBC. Without having to face a new Modern Family, the procedural drama snagged an 18% rise over last week. Actually that’s the second double-digit jump in as many weeks for SVU. Last night’s episode was the best result the show has had since the 2.0 of February 26 and just behind the 2.1 the series pulled in January 8. Lead-out Chicago P.D. (1.6/5) was flat with its April 2 episode.
