We can never know, of course, but I'm skeptical that the locker-room controversy had any meaningful impact on NHL viewership.
Now, I concede that's based on vibe, not data. I think I'm probably more of the demographic that would be likely to watch an NHL game - white, straight, male, and so forth, and it didn't impact my viewership at all. Didn't watch before, won't watch now. My guess is that the people most upset about the locker room are in a different demographic - one that is less likely to watch hockey, and I'm not sure I believe that demographic included a significant number of budding fans who would have become rabid viewers, absent the controversy. The real question in my mind is whether existing fans have ceased their support.
I know my friend
@el henry is a hockey fan, and I'm curious whether she's still watching and supporting her team. And, I don't mean to put her on the spot - but I don't actually know many hockey fans in real life outside my sister, and NOTHING is keeping her from watching her hockey games, in person or on television. And, of course, if El continues to support her NHL favorite, it doesn't imply anything about her feelings surrounding the controversy. Conversely, if she's stopped, that doesn't imply anything either.
Of course, there are always exceptions, and I'm sure that the NHL would prefer as many butts in seats as possible.
