The week to week see saw between Fox and CBS is substantially due to whichever network has the Sunday late NFL game each week, and since Fox had it last week it easily led all broadcast networks in week 11 of the broadcast season (ending December 4) with adults 18-49 with a 3.0 , ahead of NBC's 2.3 adults 18-49 rating. CBS was third with a 2.2 adults 18-49 rating. ABC was fourth with a 1.8 rating followed by Univision with a 1.4 rating. The CW finished sixth with a 0.6 adults 18-49 rating average.
CBS won the week with total viewers averaging 8.95 million viewers, ahead of second place FOX's 8.62 million average. NBC was third with 7.27 million, followed by ABC with 6.45m, Univision with 3.43m, and the CW with 1.62m.
Each adults 18-49 rating point is a percentage of the adults 18-49 US TV population and equals 1.279 million adults 18-49.
