From a CSN press release I just saw:
Last night’s Flyers-Bruins contest on Comcast SportsNet delivered the largest-ever Flyers audience for the network. This breaks the previous high, set on May 9, 2000 when with Brian Boucher in goal, the Flyers defeated the Pittsburgh Penguins in Game Six to move on to the Eastern Conference Finals. Last night’s defeat of the Bruins, to force a Game 7, averaged a 10.1 rating (300,000 households) and peaked at a 14 rating (417,000 HHs) at 10:30 p.m.
Think people are hyped up for this series? In a few minutes, we'll have a post on the atmosphere down at the Wachovia Center last night. Elsewhere, FSN Pittsburgh had its highest ever ratings for a regional sports live telecast for last night's game 7 between the Pens and Canadiens.
