The national broadcast window on Fox on Sunday earned a 17.6 rating and 30 share. The network said Tuesday that was the best since an 18.4/32 mainly for Steelers-Patriots four years ago.
Most viewers saw the Packers-Giants game in the window, with some parts of the country getting Cowboys-Cardinals or Rams-49ers.
