NBC’s coverage of Saturday’s NHL Western Conference Final Game 7 notched a ratings milestone for a hockey game: the network’s highest overnight numbers in history for an NHL game other than a Stanley Cup Final.

NBC announced that the game, in which the Chicago Blackhawks knocked off the Anaheim Ducks to advance to the Stanley Cup Final, delivered a 3.27 household rating in metered markets, based on Nielsen data.

The Blackhawks skated to a 5-3 win to reach the Stanley Cup Final for the third time in the past six years.

“The 3.27 overnight rating for Blackhawks-Ducks Game 7, in which the Blackhawks never had less than a two-goal cushion after taking a 4-0 lead in the second period, was also up slightly from last year’s Kings-Blackhawks overtime Game 7 on NBCSN (3.17),” NBC reported.

The announcement adds: “Locally, the Chicago market delivered a 26.6 HH rating, its highest ever for a non-Stanley Cup Final Blackhawks game on NBC and its third-highest overall. The Los Angeles market produced a 3.9 HH rating, its highest ever for a non-Stanley Cup Final Ducks game on NBC and its second-highest overall, trailing only the Cup-clinching Game 5 of the 2007 Stanley Cup Final (vs. Ottawa, 6.0).”
