The singing competition did see an uptick of 4 million viewers from the first half hour to the second during Thursday’s broadcast, however, and it propelled FOX to an overall win with 16.8 million viewers and a 9.4 rating/15 share.

Coming in second was CBS with 13.6 million viewers and an 8.3/13. NBC’s three-hour, six-show comedy extravaganza was good for eking out third place with 5.43 million and a 3.2/5, while ABC was right behind with 5.42 million viewers and a 3.3/5, though “Grey’s Anatomy” and “Private Practice” were reruns. The CW drew 1.34 million and a 0.8/1, but was also in reruns.

In the 18-49 demo, FOX also led with a 5.7. CBS (3.1) took second, but NBC at 2.8 had a much wider lead over ABC at 1.7 in the demo than the total viewers. The CW earned 0.5.
