NBC snagged the biggest total audience on Wednesday night thanks to "America's Got Talent," but FOX earned the best demographic numbers thanks to "MasterChef."

NBC averaged 6.85 million viewers and a 4.2 rating/7 share for the night, narrowly beating CBS (6.5 million, 4.2/7) for the top spot. FOX (5 million, 3.0/5) came in third. ABC finished fourth with 3.7 million viewers and a 2.5/4, a good bit ahead of The CW's 1.4 million viewers and 0.9/2.

FOX's 2.1 rating was good enough to lead the night in the adults 18-49 demo (despite the fact that "Masterchef" didn't win either of its hours). CBS and NBC tied for second at 1.8. ABC drew a 1.1, followed by The CW at 0.5.
