I don't know. I live in Southern Ontario, so people live and breathe hockey here, and the people who don't have surely been exposed to it enough to know whether they like it or not. No minor changes to the sport are really going to alter their opinion on it. Whether hockey gets more popular or not is dependent on expansion into foreign markets.
I don't know how reliable any data is considering people wear shirts who've never seen a game, team record ticket sales to tickets they've sold to organizations who give out their tickets to employees, and people stream so much that views are indicative of anything. So yeah, ask someone from a non-market if they've seen more people getting into the sport.
