NEW YORK — The Dallas Cowboys' victory over the New York Giants drew the most viewers ever for a "Sunday Night Football" game.

The Cowboys' 20-8 win Sunday on NBC attracted 23.1 million viewers, the network said Tuesday. The game earned a 13.7 rating and 21 share to make it the third-highest rated "Sunday Night Football" game; there are more potential viewers now, so even a lower rating can mean a record audience.

The rating is the percentage watching a program among homes with televisions, and the share is the percentage tuned into the broadcast among those households with TVs on at the time.
