NBC scores record 'Sunday Night Football' opener

Another NFL game, another record for NBC.

Last night's "Sunday Night Football" had the best opening overnight rating for any Sunday or Monday primetime game in 13 years.

The Cowboys vs. Redskins game was up 24% from last year's opener, drawing 16.6 HH rating.

The numbers suggest last week's similarly titanic season kickoff may not have been a one-time fluke. The two-game average of Thursday and Sunday's game (17.1) is the highest since the start of the scheduling format in 2002.

Also Sunday: CBS "Big Brother" (6.7 million viewers, 2.1 preliminary adults 18-49 rating) was down 13% against the increased competition and hit a Sunday low. ABC's "The Gates" (2.1 million, 0.7) was low.
