Yesterday’s action-packed Wednesday Rivalry Night game between the Philadelphia Flyers and Pittsburgh Penguins produced a .55 household rating, the highest regular season mark in NBC Sports Network history.

That 6-5 Flyers win also drew the second highest average of viewers in the network’s history, only following another Wednesday Rivalry Night game (Boston Bruins-New York Rangers on Jan. 23) for the top spot in that category. Wednesday Rivalry Night has clearly been a hit so far, as the short-running special claimed four of the five regular season averages for viewership in NBC Sports Network history:

Rangers-Bruins, Jan. 23, 2013: 956K viewers
Flyers-Penguins, Feb. 20, 2013: 901K viewers
Flyers-Bruins, Oct. 6, 2011: 874K viewers (the only game on this list that wasn’t a Wednesday Rivalry Night match)
