After the usual recap show (1.5/5) at 8 PM, Wednesday’s live America’s Got Talent (2.5/7) got down to the business of elimination at 9 PM as another round of 12 were cut down to four. With a performance by Jason Derulo and a very bright suit worn by host Nick Cannon, the American Spouses Choir, singer Jonathan Allen, dancer/martial artist Kenichi Ebina and dance troupe Chicago Boyz all made the cut and moved on to this season’s semifinals. AGT itself made the cut too with a 4% rise from its season low July 31 show. As is typical with live shows like last night’s AGT was on the East Coast, expect an adjustment later in the final numbers. The highest-rated and most watched show of the night with 10.03 million viewers, Wednesday’s AGT was up a solid 25% from the comparable results show from last year on July 18, 2012. AGT’s lead-out Camp (1.2/4) also saw a rise. The Australian dramedy was up 9% among adults 18-49 for a three-week high of its own. NBC won the night among adults 18-49 with a 1.7/5 and in total viewers with 6.790 million watching. Fox was No. 2 in the demo on Wednesday with a 1.6/5 while CBS was second in viewers with an audience of 5.628 million.

On Fox’s MasterChef (2.2/6) at 9PM, judges Gordon Ramsay, Graham Elliot and Joe Bastianich set down a challenge with sunny-side eggs and a salmon dinner. They also mixed it up a bit with a whole lot of broken plates and some Season 4 contestants returning to get back in the kitchen as the cooking competition heads toward its live rounds. The second-highest-rated show of the night, MasterChef slipped 4% from last week.

Despite the continuing blackout to 3.2 million Time Warner Cable subscribers in NY, LA and Dallas, CBS saw last night’s Big Brother (2.1/7) remain even with last week. Its repeats of CSI (1.1/3) and Criminal Minds (1.1/3) stayed the same and even rose from July 31’s 1.0 result in the key demo respectively.

Except for a new Nightline: The Lookout (0.9/3), ABC was all encores last night. The news magazine show was even with its July 31 performance.
