The NHL has made consistent effort to turn their opening night into a somewhat small-scale edition of what the NFL does. With events such as Kings of Leon playing a pregame concert in Montreal, and the banner-raising in Chicago, they have certainly succeeded in those efforts. Perhaps, then, it is a bonus that the league's opening night has progressively turned into a larger and larger ratings draw.
NBCSN's first telecast of the season, a high-scoring showdown between the champion Chicago Blackhawks and Alexander Ovechkin's Washington Capitals, drew an 0.70 rating and 935,000 viewers via Son of the Bronx. The rating was a record for NBCSN's opening night telecasts (NBC televised the opening game in the truncated 2012-13 season) and the viewership figures made it the second-most watched NHL regular season game in network history.
In the local markets, Chicago naturally dominated, with a 7.1 rating. According to NBC, that's the highest-rated regular season game ever on NBCSN. In Washington, the game hit a respectable 2.2, though it did get beaten by the competing NL Wild Card Game (3.0).
