The Vikings' loss at Green Bay on Sunday was the most-watched and highest-rated game in the five years that NBC has been carrying the "Sunday Night Football" package.

The Packers' victory had 25.7 million views and the rating was a 15.4, a figure that means there were almost 18 million households watching. It isn't the first time Brett Favre playing against his former team has meant big television ratings.

Favre's return to Green Bay on Nov. 1 last season had a 17.4 rating and 29.8 million viewers on Fox, meaning the football game had more viewers than Game 4 of the World Series between the Phillies and Yankees. The World Series had a 13.5 rating and 22.8 million viewers.

That game delivered Fox its largest audience for a Sunday NFL telecast in 14 years.
