Three years running, the Super Bowl has set a TV viewership record. CBS is hoping that happens again on Sunday.
Last year, NBC's broadcast hit an average audience of 111.3 million people.
But ratings are a mere point of pride for CBS heading into kickoff. The ads have already been sold (some at more than $4 million a pop), so the network can now only hope to put forth its best broadcast and redirect as much of the Super Bowl glow toward its other programs and its cable sports network.
Telecasters Jim Nantz and Phil Simms will call the game while more than 60 cameras cover the action - with at least one keeping an eye on the parents of 49ers coach Jim Harbaugh and Baltimore Ravens coach John Harbaugh.
