million second quiz premiere ratings TV ratings: 'Million Second Quiz' has OK start Monday, 'Mistresses' ends on high noteFast National ratings for Monday, Sept. 9, 2013

The premiere of NBC’s game show “The Million Second Quiz” scored decent but not great ratings Monday night, improving a bit the numbers for previous timeslot occupant “American Ninja Warrior.” It led its hour across the board but didn’t crack a 2.0 rating among adults 18-49.

Also Monday, the season finale of ABC’s “Mistresses” scored its biggest total audience of the summer and matched its best 18-49 rating. The U.S. Open men’s final ran well into primetime on CBS in much of the country, pushing everything else back. “Under the Dome” began airing at 10:30 p.m. ET.

CBS led the night with just over 6 million viewers and a 4.0 rating/6 share in households, pending updates for the U.S. Open runover. ABC (5.2 million, 3.5/6) came in second in viewers, beating NBC (4.6 million, 2.9/5). FOX drew 3.4 million viewers and a 2.1/3 to finish fourth. The CW (555,000, 0.4/1) was well off the pace.

ABC and CBS tied for the lead among adults 18-49 at 1.4. NBC was right behind with a 1.3 rating. FOX scored a 0.8 in the demographic and The CW a 0.2.
