With upfronts happening in NYC this week, it feels like a lot of the TV action is occurring off-screen. But the reality wars and multiple finales Monday proved the small screen still has a lot of moving and shaking going on. Coming off three nights last week of the live playoff round and a season low, The Voice (3.6/10) took a hit last night — and not just because the AC wasn’t working in the studio for the first part of the show. The Voice was down 12% to hit a performance low for this season, and while it was the night’s top-rated show, CBS’ How I Met Your Mother bested it for the first time in their overlapping half hour. Of course, with a live show expect to see those numbers adjusted in final ratings. The Voice’s lead-out Revolution (1.9/5) was also down, but only 5% from last week. NBC still won in the adults 18-49 demo, while ABC was tops in total viewers.
