Fast National ratings for Sunday, September 21, 2014.

CBS' overrun from a Broncos-Seahawks overtime Super Bowl rematch and NBC's Sunday Night Football telecast dominated primetime in all measures, overshadowing CBS' premieres for "Madam Secretary" and "The Good Wife."

In preliminary numbers, "Madam Secretary" got a good sampling with 14.28 million viewers, but did only a lackluster 1.9 key demo rating, while "The Good Wife" then sunk to 9.95 million and a 1.3 key demo rating, but since football extended roughly 64 minutes into CBS primetime for much of the country each total includes four minutes of the previous program and everybody should know better than to take much stock in the Fast National numbers.

I'll have more analysis either this afternoon with Finals, or bundled into Monday night ratings analysis tomorrow afternoon.
