They got it done in the first half against an Oakland Raiders defense that had been giving up only 20.5 points a game.
The New England Patriots held the record with 589 points in 2007. When Manning connected with Demaryius Thomas on a 63-yard touchdown play in the second quarter, the Broncos had eclipsed the mark by four points in extending their lead to 21-0 over Oakland. Denver eventually built a 31-0 lead by halftime.
Manning, who eclipsed Brady's single-season touchdown passing mark of 50 last week and is up to 55 with four more by halftime Sunday, set the single-season passing yardage record in the second quarter on a five-yard scoring pass to Thomas. He eclipsed the mark of 5,476 yards set in 2011 by Drew Brees of the New Orleans Saints.
Here are the top six teams with the most points in a season:
Denver Broncos (603 and counting in 2013); New England Patriots (589 in 2007); Green Bay Packers (560 in 2011); Patriots (557 in 2012); Minnesota Vikings (556 in 1998); New Orleans Saints (547 in 2011).
